AAFCO Dog Food Nutrient Profiles

Share

The following items represent some of The Dog Food Advisor’s most frequently asked questions about AAFCO dog food nutrient profiles.

What is AAFCO?

AAFCO is an acronym for the Association of American Feed Control Officials. AAFCO is a non-profit organization that sets standards for both animal feeds and pet foods in the United States.

What are AAFCO dog food nutrient profiles?

In order for a dog food to be marketed as “complete and balanced”, it must meet the nutritional standards established by AAFCO.

These nutritional adequacy standards are defined by two nutrient profiles based upon a dog’s stage of life…

  • Adult maintenance
  • Growth and reproduction

What does growth and reproduction mean?

Dog foods rated for “growth and reproduction” are designed for puppies and pregnant or lactating females.

How can a manufacturer claim a particular product meets one of the two AAFCO nutrient profiles?

In order for any dog food company to claim a product is “complete and balanced” for a specific life stage, that claim must first have been validated in one of two ways…

  • Laboratory analysis only
  • Laboratory analysis plus actual feeding trials

How can a consumer know which method was used to verify AAFCO nutritional adequacy?

The first method uses laboratory analysis of a sample to verify the food meets AAFCO nutritional standards. The label will read…

“(Name of product) is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles”

The second not only uses laboratory analysis but also proves that nutritional adequacy by conducting actual feeding trials with real dogs. This type of adequacy statement will probably read…

“Animal feeding tests using AAFCO procedures substantiate that (name of product) provides complete and balanced nutrition”

What if a dog food cannot meet either of the AAFCO nutrient profiles?

Any product that cannot meet either the AAFCO adult maintenance or growth and reproduction standards must state…

“This product is intended for intermittent or supplemental feeding only”

In other words, a product not intended for long-term use.

How can I tell if a particular dog food is OK for my puppy?

Any dog food that claims to meet AAFCO nutrient profiles for either “growth” or “all life stages” should be fine for your puppy.

Is it OK to feed a puppy a dog food claiming to be suitable for “all life stages”?

AAFCO only recognizes two dog food nutrient profiles

  • Adult maintenance
  • Growth and reproduction

However, manufacturers are permitted to market a dog food as suitable for “all life stages” so long as it meets the more stringent guidelines for “growth and reproduction”.

In other words, any dog food suitable for “all life stages” is also suitable for puppies, too.

    yes I tried a very gradual switch with Acana and used honest kitchen perfect form but stopped as I thought it was just masking his diarrhea and as soon as I stopped he would go back to having it again. Shouldn’t a very gradual transition not require any digestive enzymes or pumpkin? I was feeding him 2 cups ideal balance and 1/4 cup acana and he had very loose stools. With the hills ideal balance he was fine on it right away. Is it possible that he just requires a food that has a higher percentage of grains? I am looking into simply nourish as it has good ratings on this website.

  • Hound Dog Mom

    Did you do a gradual transition? Did you try supplementing with probiotics and digestive enzymes and adding a spoonful of plain canned pumpkin during the switch? Loose stools are to be expected when switching foods, especially with puppies, often a very gradual transition and the addition of the supplements I mentioned can help.

  • Susanne

    I chose the science diet because that is what the breeder had him on when I got him and he did fine on that so that is what I went back to but I tried Fromm Gold Holistic Large Breed Puppy Dry Dog Food, and Horizon Complete LB Puppy. I bought a sample bag of the Acana chicken and burbank potato but that gives him very loose stools like the others. I really want to have him on a good food but am not sure if trying so many new foods is better than just keeping him on the ideal balance. I saw that it gets 3.5 stars from dogfoodadvisor.

  • Hound Dog Mom

    You say that “the only food I could find that his stomach can handle is Science Diet Ideal Balance Puppy” – what other foods have you tried besides Orijen?

  • Susanne

    I originally had my lab puppy on orijen lb puppy but his stomach could not handle grain free. The only food I could find that his stomach can handle is science diet ideal balance puppy but I do not really want to keep him on this brand. I know acana has the chicken and potato formula that is labeled adult/all life stages. Should I try and switch my 6month old puppy to the acana or stick with ideal balance until he is older?

    I STARTED USING THE 4HEALTH FOOD FROM TRACTOR SUPPLY STORE, MY DOGS LOVE IT,I LIKE THE INGREDIENTS AND THEY GIVE YOU A HUGE BAG FREE TO TRY IT.

  • Pattyvaughn

    Not that I disagree with you, except that it isn’t two different recalls. It’s one recall that was expanded TWO more times. That is the way recalls work.

  • leo

    EVO is excellent. weight mgmt is 52 % protein .. unheard of. low carb. no grains etc. but just recalled for the 2nd time in one mo. bought out by proctor r and gamble…. problem? the hi prot keeps them feeling full longer..deciding if should switch due to recalls…???

  • Hound Dog Mom

    Hi Meagan –

    A food that’s labeled as “All Life Stages” or “Growth and Maintenance” has met the AAFCO’s more stringent nutrient requirements for growth and is, therefore, acceptable to feed to any age of dog. Fromm Classics would be acceptable to feed to a puppy, however, it’s pretty low in protein (23%) – hardly over the minimum requirement for growth (22%). If you go with a food this low in protein I’d suggest adding a high quality canned food topper to boost the protein levels.

  • http://www.dfwpugs.com/ sandy

    Yes. Growth covers the puppy stage but this food is also for adults and even when your puppy turns into a senior.

  • Meagan

    Mike would growth and maintenance be ok for a puppy? That is what Fromm Classics states.

  • Pattyvaughn

    I think they are slightly more reputable, but still cheap. Quality is not their biggest concern.

  • http://www.facebook.com/profile.php?id=1140685339 Betsy Greer

    Yeah, gotcha. I had this idea that somehow PMI was more reputable, but I still wasn’t totally confident. I appreciate your opinion.

  • Pattyvaughn

    Yeah, my gut tells me don’t try it. These are people who believe ingredients don’t matter, only nutrient analysis, so I have to assume that they use the worst quality ingredient that they can get away with. Not to mention that it is against my morals to support a company like that.

  • Pattyvaughn

    Yuck!

  • http://www.facebook.com/profile.php?id=1140685339 Betsy Greer

    Hey Patty, Does your gut tell you the same thing about Purina Mills? I tried Infinia with good success and was thinking I might try some of the other Infinia varieties, but am just getting hung up on the Purina name being part of the equation.

  • Kate

    I did a search and the only thing that came up was Alpo prime cuts. Blah.

  • Pattyvaughn

    In general, when I hear the name Purina, my automatic answer is no. But I can hope that they come out with something good finally. Is it new? I’ve never heard of it. What are the ingredients?

  • jane

    Purina Prime (turkey Is it good quality

  • http://www.facebook.com/profile.php?id=1140685339 Betsy Greer

    Hi Nina,

    There are lots of great foods that are inexpensive. You’re making a great decision moving away from the Purina products you’ve been using. I recently convinced a co-worker to switch from Purina to NutriSource. While the bag of NutriSource originally cost more, my friend quickly realized that the NutriSource was going to be less expensive for her to feed because she’s feeding less of it.

    NutriSource and Earthborn are two of my favorite budget friendly foods. Dr. Tim’s is a bit more than the other two, but still affordable. People are talking a lot about the new grain free 4Health food available at TSC. Start your search by taking a look at the four and five star food lists and compare prices at an online retailer ~ I frequently shop at wag.com and petflow.com.

    Ideally, you should fine two or three foods that your dogs do well on and rotate between them to avoid prolonged exposure to less desirable ingredients and to round out exposure to varying protein sources.

    Puppy food is a growth formula and is recommended to be used until your puppy has achieved at least 80% of their adult weight. However, “puppy” food really isn’t necessary ~ foods that are labeled all life stages and meet AAFCO guidelines to be labeled as such are appropriate for puppies as well as adult dogs.

  • Nina

    I”m trying to find a dog food for my two dogs. I have a year and a half lab/american bull dog mix who is an extremely difficult eater. She does not do well with chicken based foods. I also have a 19 week old husky. They were on Purina but I noticed that my older dog was having a hard time going to the bathroom where as the puppy had horrible gas and stool. I switched to the exclusive brand and they have been on it for a few weeks but it’s been giving them runny and soft stool. Are there any not so expensive brands that are good that I can try? And how long should my puppy be on puppy food?

  • losul

    It likely has a different mineral profile in it (mostly higher) and especially sodium and chloride.

  • Pattyvaughn

    No, puppy food is good for all life stages. Puppy food is usually made to higher standards than adult food.

  • blessedmae

    We have 4 toy poodles, 2- just about 3 yrs old, 2 4 mo. old. We feed them all puppy food – good stuff, Is this bad for the older
    ones ??? Please advise. Thank you

  • JellyCat

    It’s only rated one star because it is made of corn, corn by-products and soy. There is virtually no meat in this food and what there is slaughter house waste. In addition, this food contains 4 artificial food colors, and menadione sodium bisulfite complex, all of which are proven to potentially cause negative health effects.

  • Hound Dog Mom

    Belinda –

    Dad’s hasn’t been recalled for anything to my knowledge.It’s rated 1 star because it’s an extremely low quality food with many questionable ingredients.

  • http://www.facebook.com/ibdogluvr091 Belinda Mosteller

    i buy my dogs dads bite size and was wondering why i havent seen any recalls or anything bad from this food has there been and why is it only rated one star?

  • aimee

     losul,

    This is likely not the best definition but how I understand it. Systematics is the field of science which classifies, studies and defines relationships between species. Systemalists are those scientists in that field.

    Yes coyote are carnivores as they are in the Order Carnivora. However most members of Carnivora are omnivores. There is no taxonomic classification Omnivora : )

    As that classroom activity I linked to points out, coyotes are classified as omnivores. Their dentition, like that of the dog, is classified as non specialized. (Isn’t that your criteria of  what constitutes an omnivore?)  The pic I linked to awhile back elucidates this.

    Sigh.. yes corn starch is a fractionated component from the corn kernel and that required processing to separate it out. By raw I meant non cooked. She ate it straight from the ARGO box. And yes she did shuck and eat corn right off the cob too, when she stole it off the counter and that starch in whole corn was just as highly digestible. Coyotes also eat corn.

    Raw (uncooked) rice is highly digestible as well ( over 90%) NRC 2006.
         
    Again losul I’m not the one who is saying dogs are omnivores I’m only reporting what the experts have classified them as. Honestly, I don’t have anything else to say about the subject. 

  • losul

    respectfully Aimee

    I haven’t a clue of which “systemalists you speak of.

    “Considering my dog was raised on raw cornstarch I know things don’t have to be processed to be well used.”

    What is raw cornstarch????  Honestly Aimee, you must have the world’s smartest dog if it goes and picks his corn on the cob, shucks it, removes from the cob, and then does the following to it;

    The corn is steeped for 30 to 48 hours, which ferments it slightly. The germ is separated from the endosperm and those two components are ground separately (still soaked). Next the starch is removed from each by washing. The starch is separated from the corn steep liquor, the cereal germ, the fibers and the corn gluten mostly in hydrocyclones and centrifuges, and then dried. (The residue from every stage is used in animal feed and to make corn oil or other applications.) This process is called wet milling. Finally, the starch may be modified for specific purposes.[3]

  • aimee

     Ok then.. In the “losul system” of classification  dogs coyotes and jackals are all carnivores. It isn’t how systemalists currently classify animals but who knows maybe your system will catch on : )

    Yes they found 2-15 times as many copies but then they looked at gene expression and that is where I got the 28X’s from. It seems to be intrepreted as 28X more amylase in the pancreas ???

    “Specifically, dogs carry extra copies of the gene for amylase—an
    intestinal enzyme that cuts starch into maltose—and now produce 28 times
    more of the protein than their wolf counterparts.” The protein being amylase.

    http://www.the-scientist.com/?articles.view/articleNo/34095/title/Dogs-Adapted-to-Agriculture/

    Considering my dog was raised on raw cornstarch I know things don’t have to be processed to be well used. Similarly, fruit needn’t be rotted to be well utilized.

  • losul

    Aimee, not trying to confuse.

    I’m not calling a coyote an omnivore. I’m just saying that they can and do have a more omnivorous diet than wolves. I have no problem calling a coyote a facultative carnivore.

    But I do have a problem calling a wolf or even a dog a facultative carnivore. While wolves and dogs are able to process to limited extent some rotting fruits like apples and berries on their own, I think left to their own devices, they would have a great deal of difficulty processing things like raw potatoes, sweet or not, other tubers, carrots, corn, grains and alfalfa, brassica like broccoli and cabbage, leafy greens, shrubbery, lichens etc. In the absence of humans to grind and pulverize, cook, etc. IMO, dogs would be forced to revert back to more wolfish ways or perish. So I would have a real problem calling dogs facultative carnivores. Maybe in enough time, with humans by their sides preparing their plant material, and with natural selection doing it’s thing, dogs will more the way you wish.

    I brought the article up because it does strengthen your argument, but I didn’t read it exactly the way you did. I read it as of the dogs tested, they had between 2X and 14X the copies of a gene for pancreatic amylase production vs the wolves tested;

    “The change is at least partly the consequence of dogs having multiple copies of a gene for amylase, an enzyme made by the pancreas that is involved in the first step of starch digestion. Wolves have two copies; dogs have four to 30.”"As it happens, amylase “gene duplication” is also a feature of human evolution. Humans carry more copies of the amylase gene than their primate ancestors. People also produce the enzyme in saliva, which allows the first steps of digestion to occur while food is still in the mouth. That, in turn, rewards chewing and increases the palatability of food.”"In dogs, however, the increased amylase activity occurs only in the pancreas. The enzyme isn’t at work in their mouths, probably because the food doesn’t stay there long enough. Dogs may be able to eat human food, but they still wolf it down.”

  • aimee

     Nah…losul… The kids exercise wasn’t a jibe. Just what came up in google search. : )

     The changes in the perio skull are pretty darn impressive!

    I have to say I think you just like to confuse me! LOL
    To recap, you believe that omnivores don’t have any specializations. Yet you classify coyotes as omnivores, even though they have all the specializations that you listed which you say make a wolf a carnivore.

    I read the full text article in Nature. If I’m understanding it right dogs make 28 times more amylase as wolves???

     How about you call a dog a facultative carnivore which is essentially saying they are omnivores without using the “O” word ; )

  • losul

    Hello Aimee,

    I said previously that i would tend to agree with you more if we were talking foxes or coyotes. They do obviously have an omnivorous diet. Coyotes and foxes are adaptable survivors. They have been able to adapt and survive massive human hunting, urban spread, etc., against the odds. They still survive in great numbers throughout their original range. Wolves have not been so lucky. they have not been able to adapt near as well to a more agricultural surroundings, and life near humans. They have been wiped out through much of their original range.Was the kid’s exercise put out there as a jibe? hehe.Likewise, I have very much enjoyed our chatHere is the skull of a dog with periodontal disease just for the heck of it;http://www.skullsunlimited.com/record_variant.php?id=4774

  • aimee

     Hi losul,

    Yes Coyotes and Jackals, Maned wolves are all taxonomical classified as carnivores. All have specializations to capture and eat prey.

    By your criteria, they are all carnivores. Yet these species all eat a significant amount of plant material. “Jackals are *********. They eat 54% meat and 46% plants and have a very
    varied diet.”  http://www.blueplanetbiomes.org/golden_jackal.htmYou would fill the blank with carnivore because they have specializations to capture prey. I would fill it in with omnivore which is the original text : ) So yes we will have to agree to disagree : )I’m only providing information, the experts whose job is to classify judge by different parameters, some of which I have previously posted. I’m not saying dogs are omnivores the experts are.

    Here is a link to a kids science exercise to tell the difference between herbivore, carnivore and omnivore based on skulls. http://www.desertmuseum.org/center/edu/docs/3-4_Hunters_skulls.pdf   I’ve very much enjoyed chatting with you.

  • losul

    Aimee,

    these are what i would call carnivore specializations n wolves

    1) Obtaining the food-Cardiovascular system designed for endurance. Jaw structure designed for biting, gripping. Specialized vision system to aid proficient hunting by detecting motion. Heightened smelling and hearing for tracking prey. Social pack animals for the purpose of cooperative hunting.

    2) Eating the food-jaws hinged to move in vertical plane only. dentition designed for tearing, ripping, shredding.

    3) Digesting the food-Very large elastic stomach (about 60% of the total digestive system) to enable engorgement of a kill. Strong stomach acids and enzymes for digesting meat-carbs/starches do not even really begin to be digested until reaching the small intestine.

    As I feel that dogs are not so far removed from wolves in adaptations, I maintain that dogs are still mostly carnivorous by design, whereas they have become a bit more omniverous by intervention. That’s about as much as I can give up, sorry. I just can’t quite feel comfortable calling a dog an omnivore. Aimee, I think we’ll probably just have to agree to disagree!

  • aimee

     losul,

    You didn’t answer the question ; ) What  “carnivore specialization” do wolves/dogs possess that cause you to classify them as carnivores vs omnivores as the coyotes and jackels are classified?

    I really think that emotionally people just have a hard time saying the dog is an omnivore because they think the classification will be used as “evidence” that dogs SHOULD be feed carbohydrates and that goes against their beliefs. JMO   

    Losul, It isn’t me that is saying the dog is an omnivore, it is the phylogeneticists,  molecular systematic ecologists, systematic ecologists, evolutionary biologists…Heck I don’t even really understand well what those fields are! But those are the people whose fields of study are to classify. I’m only reporting what I have read. I’m comfortable saying the dog is an omnivore.

    “Cats originate from a family comprised only of strict carnivores whereas dogs are omnivorous” NRC 2006

     I haven’t seen it reported that to be classified as an omnivore a species has to be able to ingest/digest all types of plant material. The Maned Wolf for example takes 50% of it’s diet from one type of fruit. Dogs can digest fruits without processing.  Will they get much out of grass?? No but then again either would I : ) 

    I don’t know in absolute numbers what percentage of species are carnivores, again I’m not the one classifying them, but among mammals, felids, mustalids, seals, and killer whales come to mind. 

     

     

  • losul

    Wow Aimee,

    I’m beginning to feel like a single dog separated from the pack and trying to take on a Polar Bear, hehe.

    I would think you would have to concede that dogs, without human intervention, have a great deal of trouble digesting most plant matter. By human intervention, I mean grinding, pulverizing, cooking, freezing, separating, treating, adding enzymes, etc.

    In your previous posts, you seem to believe that dogs ancestors were more omnivorous and time and environment has adapted then to become more carnivorous. I see it just EXACTLY the opposite.

    If we were to completely disregard all the herbivores, it seems to me that you would classify 99.9% of all the remaining species as omnivores. Which was a point I brought up earlier in the thread.

  • aimee

     losul,
    Ok…I’m still getting stuck on your proposal that omnivores don’t have any specializations.  So I’ll ask what are the carnivorous specializations that the wolf/dog have which separate them from Coyote and Jackals which are omnivores?

    Then there is this: “Dogs also possess a posteriorly recurved coronoid margin to the
    ascending process of the lower jaw, which all wolves lack, except for
    the Chinese C. l. chanco known from Mongolia and China. This form of the coronoid is characteristic of omnivorous CARNIVORES (bears, raccoons, etc)”

    http://www.thecanadianencyclopedia.com/articles/wolf

    Yes Polar Bears eat a carnivorous diet but does that make them a carnivore or are they simply omnivores ( as are all the other bears) who don’t have access to vegetation by virtue of their environment.  I think they are the later. The Inuit eat very little plant matter, but they are still omnivores.

     Look at how this zoo feeds it’s Polar Bears. ”

    At the Zoo, just one of our polar bears can consume one to five pounds
    of mackerel and ground meat and four pounds of omnivore biscuit (a chow
    specially formulated for bears) a day.
    Forage foods are also provided and can include apples, raisins, peanut
    butter, honey and dehydrated fruit.”  

    Are wolves true carnivores or are they metabolic omnivores, as dogs are, who by virtue of their environment eat primarily meat? I have seen it written that wolves would likely eat a much more varied diet if they weren’t restricted to the areas that we have restricted them to.
     
    More food for thought?

  • losul

    hehe, and i am sorry I missed yours. ( well maybe not too sorry after reading Kateicy’s post today with this link, so I’ve softened my thinking somewhat). Very good article I think.

    http://www.washingtonpost.com/national/health-science/learning-to-love-cereal-was-key-to-the-evolution-of-dogs/2013/01/23/30c47500-6510-11e2-85f5-a8a9228e55e7_story.html

    No, i don’t believe real omnivores have any specializations one way or the other.

    I still don’t think that dogs are so far removed from their ancestors that they don’t retain much of the wolves carnivorous specializations. Dogs (feral) left to fend for themselves will still often form packs and hunt  prey (and scavenge as neccesary for survival). A dog can still quickly digest animal matter, whereas plant matter and carbohydrates, especially raw, can be a real challenge. No doubt they have adapted somewhat to living with humans. I’d have to think about more.

    Polar bears eat an almost absolute carnivorous diet, so I wouldn’t call them an omnivore. Perhaps brown and black bears have evolved more to a omnivorous diet.

    So I agree that dogs certainly have some flexiiblity in their requirements, but not very much without human intervention. To me, a dog is still basically a carnivore.

  • aimee

     Hi losul,

    Sorry I missed your reply.

     Interesting way of approaching it. Does an omnivore not have any specializations  for eating plants and animals or do they have specializations for consuming both plants and animals?

     What do you consider to be specialization?  Is the large canine tooth is a carnivore specialization?  Bears, a poster child omnivore, have large canines.

    So sure dogs have “specializations”  for  eating prey. But does this make them specialized? The dentition of the cat is considered specialized while the dentition of the dog is considered non specialized.

    The take home message is that dogs have flexibility in their requirements. They are generalists, whereas cats are not.

  • losul

    Sandy, 

    I had no idea you could do that, tried it and thanks, very helpful.

  • losul

    This would’ve been a great place to have this discussion;

    http://www.dogfoodadvisor.com/canine-nutrition/dogs-carnivores-omnivores/

  • losul

    Hello Aimee,

    As usual, you bring excellent and interesting points to the discussion.

    Nevertheless, I would tend to agree with you more if dogs were more closely related to coyotes or foxes rather than wolves.

    Regardless of any taxonomic classifications (dogs and wolves are classified as carnivores), I prefer to think in terms of these definitions;

    1) A Herbivore is an animal that has specializations/adaptations for eating plant matter.
    2) A Carnivore has specializations/adaptations for eating animal matter.
    3) An Omnivore has no specializations for eating either plant or animal.

    Which begs my next question;

    Do you believe that dogs (or wolves) have no carnivore specializations?

    P.S. I really wish there was a way to move the entire discussion to the proper place. I find the topic fascinating, especially when discussing with you.

    All you have to do is look at the higher rated foods here. And you can find some of these foods fairly easily. Ordering online is easy and you can find free shipping, but if you must go to a store PetCo carries a few of ‘em.

  • Ibdogluvr091

    i have a question to ask being dads dog food is only rated one star is it good for dogs and why is it every dog food has corn and corn gluten in it which is bad for dogs so what kind of food is safe and doesnt have these things in it?

  • aimee

     Hi Pattyvaughn,

    I’m glad you found the post interesting. It is another way of looking at the issue.

  • Pattyvaughn

    I think that’s what I did.  It just took me all day long to think to try to find it that way:-}  One of these days I’ll learn…

  • http://www.dfwpugs.com/ sandy

    you can also go to “comment history” and see more posts that way.

  • Pattyvaughn

    I’ve been looking for this post all day because I couldn’t remember which thread we were on and it finally occured to me after 9:00PM that I could look at my posting history to find the thread.  I,ve been trying to remember that I wanted to come back here and reply to this post because I wanted to say that this argument for dogs being omnivores is the best one you have come up with yet and I enjoyed reading it very much.  Even when I don’t agree with you, I love to learn from you, and I respect you.  Who knows, with a little more time to ponder, I may come to agree with you, but I still know my dogs have done best eating like carnivores and I’ve fed both ways, mostly for omnivores. 

  • aimee

     Hi losul,

    I likely take a more evolutionary approach than others. I classify dogs as omnivore with carnivorous bias based on the retention of omnivorous traits.

     As animals become more and more specialized in their diet they lose metabolic pathways for which there are no pressures to maintain. Carnivores eat a nutritionally complete diet and so have maintained fewer metabolic pathways than a dietary generalist, the omnivore.
     
    Metabolically dogs are flexible which is a trait of omnivores.  Dogs can synthesize Vit. A  from carotene, they can convert tryptophan to niacin, cysteine to taurine etc. All pathways lost in the carnivore  the cat.

    Dogs can up regulate and down regulate protein metabolism allowing them to adjust to various dietary protein levels. Carnivores, always eating a high protein diet have lost this flexibility.

    Carnivores, always eating a complete diet had no evolutionary pressure to maintain the ability to select diet based on nutritional adequacy. Cats can not select a diet based on need. They readily will eat a diet devoid of protein when given a choice between a diet with adequate protein and one with no protein at all,  they can’t discriminate. Dogs when offered diets of differing protein will select and choose to eat about 30% of calories as protein, same as the omnivore the rat.

    Dogs can detect sweet allowing them to choose easy sources of energy and they preferentially choose sweet foods. Sweet foods are usually “safe” foods to eat. Cats didn’t maintain this ability to detect sweet, no pressure to maintain it as they don’t select a varied diet as omnivores do.  Dogs intestines are rich in enzymes which break down carbohydrates as opposed to carnivores .

    Omnivores are expected to have various detox pathways in the liver to degrade plant based toxins. Carnivores don’t encounter such toxins. Dogs have a pattern consistent with other omnivores whereas cats, a carnivore have few.

    But dogs have lost some omnivore traits which is why I say they have a carnivorous bias. They don’t detect salt well and they don’t synthesize Vit. D

    So I see the dog as having drifted a bit away from a omnivore prototype but maintain far too many omnivore traits and abilities to classify them as a carnivore.

     Hi Pattyvaughn,

    Yes dogs do lack all of those things….. so do bears which are omnivores.

    These pics hopefully will illustrate what I mean by flattened molars in dogs vs pointy ,molars in cats. 

  • http://www.thegreedypinstripes.com/ BryanV21

    I believe a dog is a carnivore with omnivore tendencies. Everything about them points to carnivore, but they have been known to eat fruits and vegetables in the wild. 

    What some people refuse to understand is that there are different types of carnivores. Just another example of people living in a black and white world, and ignoring the gray areas.

  • losul

    Oh boy, this conversation we should have took to the forums.

    Would it be more right to say a dog is a carnivore with some omnivorous tendencies, or a dog is an omnivore with some carnivorous tendencies?

    Hi Aimee

    Dogs lack all these things not just one.  Your dogs teeth may be flattened, but mine aren’t, they all are pointed and have no pockets that food can rest in to be crushed in chewing.  And herbivores don’t need to produce cellulase if they are designed to carry the bacteria that break down cellulose, that has nothing to do with omnivores.  I also know that it doesn’t matter what I or anybody else here says, you believe dogs are omnivores.  I disagree, they have too many exceptions to the things that define an omnivore.  I haven’t heard any evidence of anything that contradicts the definition of a carnivore.

    I think you have an incredible knowledge base and I really respect your ability to apply that knowledge, but that doesn’t mean I can agree with you.  So we will just have to agree to disagree.

  • losul

    I don’t have any argument with that, my argument is that you’re calling a dog an omnivore, when they are primarily carnivorous by design.

  • aimee

     Hi losul,

     I have posted here before about deer eating birds and rabbits eating lizards as examples of why I don’t think it is valid to classify an animal as herbivore omnivore or carnivore solely based on what they are seen to eat.  

  • losul

    But Aimee if you want to call dogs omnivores with a dietary slant, you just as well call ALL animals omnivores with dietary slants one way or the other, don’t you think? What is a carnivore then? Or maybe there should be a reclassification for dogs to a cornivore? Bad joke I know.

    Would you call a deer, an omnivore with a plant based dietary slant? They are known to occaisonally root through gut piles for fat, possibly even bone tidbits. Some have been reported to eat eggs out of nests, and it’s well documented that they sometimes even eat the wings and legs off birds, especially males that need more calcium. Even so, I wouldn’t call them omnivores with a plant based dietary slant.

    Speaking of deer, many animals considered herbivores or primarily herbivores will chew on shed deer antlers for the mineral content. Shed antlers never last long in the wild.

    Antelope will occaisonally eat lizards and rodents. The same with squirrels.

    Some parts of the world, especially where phosphorous is deficient in soils, cows have been known to chew on animal bones and carcasses to satisfy that craving for phosphorous and/or protein, even though they sometimes die from botulism, or other disease they weren’t really able to or meant to cope with. And what about the bugs they eat along with the mouthful of grass?

  • aimee

     To say dogs are not omnivores because they lack salivary amylase implies that salivary amylase is a criteria or a trait of omnivorous animals. It is not. All omnivores do not have salivary amylase.

    Ditto for the argument that they are not omnivores because they lack significant side to side lower jaw movement. Most omnivores have a simple hinge joint.

    Dentition can be seen as mixed, as the molars are flattened.

    True, dogs do not produce cellulase but then again herbivores don’t either.

    Many omnivores have a bias toward either a plant based or animal based diet. Dogs are omnivores with an animal based dietary slant.

  • LabsRawesome

     Toni I think you meant obligate carnivore not “obligatory”.

  • http://www.thegreedypinstripes.com/ BryanV21

    Dogs are not “true” omnivores. Just because they CAN eat fruits and vegetables, does not mean they can live off of them. Being an omnivore means one can live off of either animal or plant-based foods, not that they can “do alright for a while as vegetarians”.

  • Pattyvaughn

    Seriously?  Dogs are not omnivores.  They lack salivary amylase to start the breakdown of starch in the chewing process, oh wait, they lack the teeth to chew plant matter at all.  They also don’t produce cellulase, which is necessary to break down plant cell walls.  They can survive on the plant material in kibble because of how it is processed, not because dogs were made to eat plants.  Remember how scientist, doctors, and nutritionists are always telling us to stay away from processed foods because they are unhealthy for you?  Kibble is about the most processed food in the world.  Dogs are carnivores and made to eat meat.

  • Toni

     Do yourself a favor and switch to Blue Buffalo.

  • Toni

     Dogs are omnivorous, and can do alright for a while as vegetarians, but should have meat in their diet. Cats on the other hand are obligatory carnivores which means, “they MUST eat MEAT.” They should be restricted in their carb intake, and fed as close to pure protein as possible. This is not routinely done, and it is probably why we see so many sick cats.

  • Toni

    Yeah, read “Food Pets Die For” by Ann Martin. You WILL find it GROSS what is done to not only our animal pets, but the food chain in general. It is only a matter of time before people in the US start contracting BSE.

  • Jrandall1258

    I read a lot about that and wondered why our three dogs never experienced any problems.   They had been eating California Natural Lamb and Rice for over five years at the time that Proctor and Greedy bought Naturapet.  I recently very slowly transitioned them to grain free chicken and rice and haven’t seen any problems.  My long term goal is to feed my dogs regular food. I’m currently reading “Raw and Natural Nutrition for Dogs” The Definitive Guide to Homemade Meals by Lew Olson, PhD.  We should all feed homemade and put the greedy corporations out of business.

  • LuvCowDogz

    A word of advice. Evo is owned by Proctor & Gamble now. They bought out Naturapet a couple of years ago. They said they weren’t going to change anything prior to the take over, however I’ve read reviews from long time buyers of some of the foods they now own saying their pets have GI issues, gas, etc. So just be aware of this. Always look at the legal documentation to see who “really” manufactures the diets.

  • Pattyvaughn

    Dogs have no carb requirement at all.  People have been feeding low to no carb diets to dogs for many years and they thrive on it.  Yes, they can survive on a vegetarian diet, but I can survive on a diet of candy bars.  That doesn’t mean that is what I should eat or that I’d be particularly healthy on it.

  • BryanV21

     No, because dogs are primarily carnivorous.

  • Cworthen12

    Is anyone concerned about the fact that dogs are primarily omnivorous, and must have a carb:protein ratio of 2 or 3 to one? They can even do well on a vegetarian diet (tho might get a bit gassy).

    Is there a no salt/very low salt dog food I can try for my 11 yr. old Boston.She also loves treats,are there any that wouldn’t cause problems with her congestive heart failure ?

  • Annette

    my dog’s eat blue basics. has any one heard of calcium build up, from this food?

  • BryanV21

     I didn’t mean to imply you didn’t know, just wanted to add that to the conversation as it seemed to fit.

  • Hound Dog Mom

    Yes, I’m aware of how to calculate the carbohydrate content of food. :)

    What I’m saying is calories in a food are comprised of three components: protein, fat, and carbohydrates. A food has to have a high protein and fat content in order to have a low carbohydrate content. Moisture and ash levels are fairly similar from kibble to kibble so for comparative purposes it’s quickest to compare protein and fat levels.

  • BryanV21

    The good Dr. here has a formula for figuring out the carb level of foods. Add up the protein, fat, moisture, and then add 8 for the average amount of ash in a dry food (he says 6-8%, but uses 8). Take that amount and subtract it from 100, and that is the carb content of the food.

  • Hound Dog Mom

    John –

    The following foods have the highest level of protein that I know of for dry foods (could have missed a food, but I think this list is pretty accurate):

    Wysong Epigen 60%

    EVO 42-52%

    Premium Edge Healthy Weight I 44%

    Artemis Fresh Mix Maximal 42%

    Pinnacle Peak Protein 42%

    Nature’s Variety Instinct 35-42%

    Solid Gold Barking at the Moon 41%

    Wysong Optimal Performance 40%

    Orijen 38-40%

    I agree with Storm’s Mom that checking out raw and canned foods will increase your options. All dry foods are going to be fairly carb heavy – even the higher protein ones. 

    Generally the higher the protein level the lower the carb level, although fat levels need to be considered as well. Protein, fat, and carb percentages comprise 100% of a food so, for example, if two foods have the same exact protein content the food with the higher level of fat will have less carbs.

  • Storm’s Mom

    You’ll find a lot of the higher-protein (though not necessary low carb) ones here:

    http://www.dogfoodadvisor.com/best-dog-foods/best-grain-free-dog-foods/best-grain-free-dog-foods-dry/

    You might also want to check out the Best Wet Dog Foods, too, as wet food is much higher in protein than dry food, so you could feed a lower protein dry food and top it with a wet food to get an overall higher protein meal.  

    Hope this helps!

  • John

    I really appreciate this site, but I have found 1 flaw with it.  I wish there was a way that you could search the dogfoods by what your looking for.  I have been hunting for almost a full day trying to find a “low carb” high protien food. If anyone has a suggestion please let me know.

  • jim

    Why no reviews of the leading dog foods? And why do all the same stores show up when I search for dealers?

  • Alexiswyo

     There are also a few other companies who use European vitamin packs-Nutro Ultra and Annamaet are two that I know of.

    How do the AAFCO standards compare with the NRC guidelines?

  • Cookie_346

    Am using Blue Buffalo seinor as I took two bags of TOTW that was on the recall list. I have 4 dogs and all four had diharria . My yard is double fenced to keep out other animals and since the dogs did not want to eat the TOTW food I knew that something was wrong. Yesterday On HLN I saw that TOTW had also been recalled, both bage that I had was on the list.
      My male shelty had bloody diharriah for a week. My vet, yes people, I have over four hundred dollars in vet bills because of this mess and I most certanly did take my dogs to their vet.
      I even added cooked boneless, skinless chicken breast and white rice to the dry food to get them to eat it. I feel blessed now that I kniow what it was that I did not loose any of my dogs. I am 66 years old and they are like my children. I really am tempted to start feeding them what I can cook if this recall continues to grow. God Bless our Fur Babies.

    Hi Jaime,

    I’m sorry you feel this FAQ “confuses the customer”. For that was certainly not my intention when I wrote it.

    Nowhere on this page do I claim AAFCO “authorize, certify, test or otherwise approve animal feeds”.

    It only publishes guidelines detailed in its only two nutritional profiles – which is clearly explained in this document.

  • Jaime

    Your web page confuse the customer specially with the AFFCO information. I suggest to you to to AFFCO web page, below some findings:
    Does AAFCO certify products?

    No.  AAFCO has no regulatory authority to regulate feeds (and pet foods).  AAFCO also does not authorize, certify, test or otherwise approve animal feed. Only the individual states have the authority to approve animal feed to be distributed in their state under the authority of their state feed law. All of the states except Alaska have a commercial feed law. While each state (except for Alaska) has their own feed law and regulations, the labeling requirements of most states are similar and closely resemble AAFCO’s model regulations; however, some state laws can be very dated and others may be more up-to-date. For this reason, many companies find it easier to label their products according to the AAFCO models rather than try to comply with all of the different versions of the feed laws and regulations adopted by the states. If you follow the AAFCO Model Pet Food Regulations, you will probably meet all the states’ requirements”

  • Jan_Mom2Cavs

    In my opinion, I would feed both the Shih-Poo and the Yorkie Innova over the Iams.  If the Innova doesn’t agree with them, there are plenty of 4-5 star, and even some 3 star, foods that should be healthy foods for them.

  • Prazhm4

    I have a 2mo old yorkie and I have started him on Innova, I have a shih-poo as well. Yorkie was eating shih-poo’s Iams and I was told not to buy Iams for him, start him on the Innova. My question is what food would be best for my yorkie?

    Thanks,
    Elizabeth

     yes, Vitamins are too toxic to to create which means its too expensive to make in the US. There are some manufacturers in Europe, but they are too expensive to put in dog food unless its Ziwi Peak (but a 10# bag of Ziwi retails for $125.00)

    Hi Massweet,

    The answer to your question may be found in my article, “Still Think Your Dog’s Food Is 100% China Free?“.

    Hope this helps.

  • Massweet

    What about the vitamins. Are they imported from China as I have been told?
