Garlic in Dog Food — Good or Bad for Your Pet?

Share

Garlic is widely regarded as a safe and healthy supplement. So, it’s frequently added to many commercial dog foods and treats. Garlic’s claimed benefits include:
Garlic Bulb and Cloves

  • Anti-bacterial properties
  • Flea and worm control
  • Digestive support

However, some warn that garlic is toxic to dogs and should never be added to an animal’s diet.

With so much at stake, it’s important to question both the positive and negative effects of garlic — before deciding whether or not to make it a staple in your dog’s daily menu.

The Case for Garlic

In the following video, Dr. Deva Khalsa, a holistic vet, presents the argument for garlic. And even though she’s obviously promoting her nutritional supplements, Dr. Khalsa makes a solid case for feeding controlled amounts of garlic to a dog.

Questionable Benefits

However, many pro-garlic claims have never been proven — and are only considered possible benefits for humans.

Take, for example, garlic’s most popular homeopathic claim that it naturally prevents fleas, worms and other parasites.1

Despite the abundance of products that utilize garlic as a means to control fleas, research supporting its effectiveness is lacking.

Toxic in Large Doses

There are also specific health risks associated with garlic. That’s because like other species in the Allium family, onions and garlic contain aliphatic sulfides.

And when eaten by a dog, these same sulfides can produce telltale inclusions of denatured hemoglobin — the oxygen transport molecule — found within the animal’s red blood cells.

These so-called Heinz bodies can burst and decrease the numbers of red blood cells in the animal — a dangerous condition known as hemolytic anemia.2

And in acute cases, garlic poisoning can lead to nausea, vomiting, diarrhea, elevated heart rate, weakness or even collapse.3

That’s why garlic is considered toxic to dogs and cats by the…

Invisible Damage
to Blood Cells

Fans of garlic would argue that it can take a significant amount of the ingredient to produce the kinds of clinical effects seen with this type of anemia.

And that’s true — at least for clinical signs. Keep in mind — these are the signs of disease that can be easily seen with the naked eye.

However, what about subclinical signs — the invisible damage seen only with the help of a microscope or lab tests?

In this video, Dr. John Tegzes, a veterinary toxicologist, warns about the damage that can be done to a dog’s red blood cells:

According to another vet toxicologist, Dr. Sharon Gwaltney-Brant, even in small amounts, garlic has demonstrated a proven ability to cause subclinical damage to a dog’s red blood cells.4

And in a peer-reviewed article, Allium poisoning was found to not only follow the consumption of a single large amount of material but also after repeated smaller doses.5

The Bottom Line

When used in larger doses, no one will argue that garlic and onions can be toxic to dogs. Yet one must also think about the potential health risks in feeding smaller amounts, too.

On the other hand, with many years of safe use behind it, garlic’s universal acceptance among pet lovers cannot be ignored.

So, be sure to consider the pros and the cons of feeding garlic on a daily basis when making your next dog food purchase.

    Do you understand the stupidity of your comment? Both cooked or raw bones will splinter. Clearly you’ve never had to chop a whole chicken into 1-2 inch pieces for a curry. I do this with a meat cleaver at least once a month. Raw bones splinter the same. So what now? Any more unfounded excuses to demonize something you have no clue about? First garlic. Then chicken bones. What next!?!

    P.s. also mostly of what I give are breast plates, backbone and wing bones. My butcher has no use for these. I tell him to phone me as soon as he gets to 12 pounds, freeze it and I buy it from him.

  • John Tetreault

    That’s the difference. Cooked bones splinter and are dangerous. Ever seen a pack of wild dogs cooking their kill over a campfire? Yes they evolved eating bones. RAW bones. Not cooked

  • Pitlove

    Hi Sadie-

    Garlic toxicity can cause inclusions on red blood cells called Heinz Bodies. They will only be seen during a manual differential under the microscope by the vet or vet tech. Blood work results printed out from say an Idexx catalyst won’t reveal them.

  • Marie Peppers

    oh the turkey is good as it’s a lean meat. Just be careful on beef or organ meats with seniors. Also, make sure you add a good quality supplement to their program daily. We use this one and we add it to the food AFTER the food is cooked, See here http://www.nuvet.com/81098 ( nuvet plus in powder or wafers)

  • disqus_SBl7sCuYS7

    heinz body anemia

  • disqus_SBl7sCuYS7

    I can tell you that raw garlic gives me terrible heartburn, so, I have to watch my intake.
    It also causes me to have an offensive body odor 🙁

  • disqus_SBl7sCuYS7

    Addendum:
    A few years ago, I believed what some homeopathic vets had to say. So, I was giving my 20 pound terrier miniscule amounts of fresh garlic for flea/tick control (totally ineffective btw)
    After about 2 weeks he had a couple of episodes of nausea/vomiting, a visit to the vet ruled out pancreatitis and his other labs were normal.
    I stopped all fresh garlic and he never had an episode like this again, it’s been 4 years. I was too embarrassed to tell the vet I had been feeding garlic, but I suspect that was the cause.
    I don’t think the minute, over processed amount of garlic added to some kibbles bothers them much though.

  • disqus_SBl7sCuYS7

    It could have a slow cumulative effect.
    More info here: http://skeptvet.com/Blog/2012/02/garlic-for-pets-whats-it-good-for/
    Excerpt below, click on link for full article, the comments are informative too.
    Bottom Line
    In vitro and lab animal research suggests a number of potential uses for garlic. The same level of research suggests some potential danger to garlic use in dogs and cats. There is almost no clinical research to substantiate any of the claims made for garlic use in pets. Traditional use suggests almost every pant is a cure-all, and the majority of such claims have yet to pass the test of scientific study. So at this point, hysterical claims of garlic as a “miracle food” are totally unjustified. The potential benefits deserve to be investigated, but they are mostly theoretical and unproven. The risks are probably low overall, but some individuals have been harmed by eating garlic, and we are currently unable to predict accurately which patients will be adversely affected.

  • Sadie

    If a dog were to be unlucky and have toxic signs from garlic consumption, how might this show up in their labs? I hope mine are all doing fine but would like to take a closer look at this since they are all tiny.

  • Sadie

    Marie, i add lean and extra lean boiled turkey to their base mix, Kindly. I do tend to give them a little more meat than the recommendation but not much. My four dogs are seniors, two are senior seniors. Do you think some seniors need less protein? Thanks

  • Marie Peppers

    it may be you are feeding too much protein. Try one with less protein if possible or a lower fat protein

  • Marie Peppers

    Garlic and your dog; Yes you can give garlic to dogs in moderation, See here for suggested dosages on Garlic for dogs, http://bulldogvitamins.blogspot.com/2016/02/the-good-and-bad-of-dog-flea-treatment.html

  • Calife

    I saw a video where a really young vet (like someone from Scrubs) was lambasting onions and garlic and my gut instinct & decades of experience was telling me “this must be pure hokum.” Glad I found this page i.e. bad in large doses!

    The other thing internet people like to criticize is roasted chicken carcass. I mean seriously, who throws away their KFC bones? I even buy hot wings for my dogs on their bday! I won’t deny that there are stupid dogs out there (so you need to cut up the bones or whatever) but my dogs have zero problems. To me, we should remember that dogs used to be wild creatures – didn’t even eat cooked meals back then. Lived in the cold and rain. Now they are fed cooked meals, given multi-vits and live till natural death (15 yrs).

  • Sadie

    Honest Kitchen Kindly mix has garlic in it andnive been feeding it to my 5lb Chihuahua with IBD. Ugh. He’s not really getting better and has to take Pepcid. I feel like it’s the garlic to blame. Anyone have same issue or can tell me more?

  • Crazy4cats

    Actually, I think there is some risk with any type of flea, tick, and/or heart worm prevention. One just has to go with what they think is best for their situation.

  • Crazy4cats

    Hi Aliosh-
    It’s nice to meet you too!

  • Crazy4cats

    Agreed, it is good info. My father actually knows someone whose cat died after applying topical flea prevention. I’m guessing they used the same stuff on their cat as their dog thinking it was ok for either. Read the labels, guys! I have not used garlic as a flea preventative for a few years now. I only use the topical twice per year. Once in June and then again in Sept. I haven’t had any issues with fleas so far. I live in the Pacific NW where they aren’t quite as bad.
    However, Giardia is rampant here due to mild wet conditions and I would probably use a little fresh garlic to rid them of that nasty parasite if they get infected with it again.

  • disqus_SBl7sCuYS7

    Well, it doesn’t hurt to put the info out there. Someone else reading these comments might not be aware. And, a lot of folks don’t check with a vet before they try things.
    Also, , the minute amount of garlic that is added to dog foods is probably okay.
    But, giving them fresh cloves is a bad idea, imo, it can have a cumulative effect and the damage can show up later.
    Garlic supplements meant to deter bugs…..No way, Jose!

  • Crazy4cats

    Yes, I’m aware of Advantix’s risk to cats. That is why I use Advantage if I use topical flea protection on my cats AND dogs. Thank you for your concern though.

  • disqus_SBl7sCuYS7

    Advantix is also a topical solution for the treatment and prevention of fleas, ticks, biting flies, mosquitoes and lice on dogs. The product’s active ingredients are imidacloprid and permethrin. It is the addition of permethrin to the recipe that makes the deadly difference.
    Dogs can metabolize permethrin effectively, resulting in a safe product for them. However, cats cannot metabolize this ingredient, and will suffer from toxic effects if exposed. Cats are exposed to Advantix in a variety of ways, including direct application, close contact with a dog who has been treated within 48 hours, or if they have groomed a doggy pal’s fur after an application.

  • aliosh

    You are all putting pesticides on your dogs without worry while fearing the effects of garlic… You all have been brainwashed by the veterinary industry. These topical are much, much more dangerous than garlic in appropriate doses.

  • Very glad I saw this. Canine Carry Outs have garlic powder in all of their treats, and they’re my dog’s favorites, so I panicked when I saw the ingredient listed. Fortunately she seems okay. I just want what’s best for her.

  • mahoraner

    I use k9 advantix, but really its the same as advantage just with a tick prevention,

    and when you live near a forest, that is what you need

    But both of them are great for fleas

    just remember that advantage doesnt prevent ticks! (i learned that the hard way)
    so if you live in/or near a wooded area with lots of ticks, use the advantix instead

  • Crazy4cats

    I’ve had good luck with Advantage in the last couple of years too. Thanks for the recommendation.

  • John Edwards

    advantage works a lot better and for much longer than it is supposed to in my experience. i have a 24 lb beagle russell terrier mix who spends a fair amount of time outside. i apply one tube of the medium size dog dosage (weightwise, he is on the lower end of the large dog dosage recommendation) to him every 3 or 4 months and he has never had a single flea. i cant speak to the efficacy of the garlic or not as i avoid letting him ingest any garlic, but thought i should mention that. it could quite feasibly be the advantage. imidacloprid is possibly the most powerful insecticide on the market these days from what ive read.

  • Cheri Fellinger

    WTF? I didn’t understand a sentence.

  • patti Clark

    I make my dogs formula with hamburger or ground turkey, raw oats and chia seed. I did add garlic powder but I am so confused about the garlic. Years ago I gave it to my poodle and had him put down at 13 because of rectal tumor. He had no fleas and no worms and I saw no problem with the garlic.

  • Crazy4cats

    Hi Regina-

    I’m just curious, are you feeding garlic for flea prevention, or just for general health reasons?

    Here is a link from a Dogs Naturally Magazine, a holistic approach to pet nutrition and care, with some dosage recommendations :

    http://www.dogsnaturallymagazine.com/is-garlic-bad-for-your-dog/

    Summer before last I included “Bug Off” garlic granules in my dog’s food everyday for flea control and I did not notice and bad side effects. And…they did not get any fleas! I also gave fresh garlic to them 3 or 4 times per week when they had a bad case of Giardia with no apparent side effects.

    I now, however, with the controversy surrounding it, have decided to eliminate it from their regular diet and they still didn’t have any fleas. (knocking on wood)

    But…I definitely would feed again if they end up with another case of Giardia. I do think it is effective as a parasite remover and would be worth the small risk involved.

    Good luck!

  • Shawna

    Only Natural Pet website quoted Dr. Pitcairn’s book “In Dr. Pitcairn’s Complete Guide to Natural Health for Dogs & Cats, Dr. Richard Pitcairn recommends up to ¼ clove of garlic per day for cats and ½ to 3 cloves for dogs. As with most herbs, at least one day off per week or a periodic week off from garlic is a good idea.” http://www.onlynaturalpet.com/holistic-healthcare-library/fleas-ticks/80/garlics-many-health-benefits-summary.aspx

    Most of us give garlic on the lower end of what is recommended per size and only 3 to 4 days per week.

  • el doctor

    Hi Regina, welcome to DFA!

    There is evidence that garlic damages red blood cells in dogs, even in small amounts.

    In small amounts there is a small amount of damage, in large amounts there is a large amount of damage. All of my references to garlic apply to onions, scallions, chives, leeks, etc.

    When dogs consume small amounts of garlic they don’t show any observable signs of toxicity so people assume there is no damage being done.

    On a cellular level, even small amounts of garlic fed to a dog will cause red blood cell damage. Garlic causes red blood cells to rupture (hemolysis).

    Here are some quotes from Vets and Veterinary Toxicologists (experts in poisons), that point out some of the dangers of garlic.

    R.B. Cope, BSc, BVSc, PhD. –
    Allium species toxicosis typically ensues after consumption of a single large quantity of thematerial or repeated small amounts

    “According to vet toxicologist, Dr. Sharon Gwaltney-Brant, even in small amounts, garlic has demonstrated a proven ability to cause subclinical damage to a dog’s red blood cells”

    Shawn Finch, DVM –
    “However, I believe that any amount of garlic or onions is unacceptable, because it always causes damage on a cellular level, whether or not we notice the effects of the damage and label it “toxic.””

    Dr. Justine Lee, associate director of Veterinary Services at Pet Poison Helpline and a veterinary emergency critical care specialist.

    “I would never recommend adding any garlic powder to your pet’s meal; you could potentially injure your pet over time.”

    “as little as one clove of garlic can
    lead to toxicity in dogs and cats.”

    “Using garlic as a homeopathic treatment for flea prevention has been debunked as not effective,” says Lee. “I would never recommend adding any garlic powder to your pet’s meal; you could potentially injure your pet over time.”

    I hope this helps you make a more informed decision about feeding your dog garlic 😉

  • Regina

    I have a 100 lb red nose pit.. How much garlic should I add to his diet?

  • el doctor

    SMH

  • theBCnut

    So you agree with my original statement as written. Garlic does not cause BLOODY diarrhea and pancreatitis. Though in large amounts it MAY cause a host of other problems. Good to know.

  • Phyuck Yiu

    Garlic has worked wonders for my dog’s allergies, it’s amazing. My dog has been struggling with chronic ear infections the past couple of years, and just recently his nose was getting all gooey and cracked. He’s older so his immune system is breaking down more rapidly.

    Just 3 days ago I started giving him garlic, his nose has completely cleared up and his ear is FINALLY clearing up, I see no signs of it getting worse and it looks like it’s healing.

    I’m going to continue giving him minced garlic in small doses each day, the benefits are amazing. I’ve seen nothing but positive things so far from dog owners that have consistently fed their dogs garlic with absolutely 0 problem.

  • el doctor

    What you said was:

    “Um, NO! Garlic in large amounts MAY cause anemia, then again it may not. It certainly does NOT cause pancreatitis and bloody diarrhea. Good grief.”

    I replied to you because “Garlic in large amounts” “has caused a host of negative symptoms in dogs and cats, including diarrhea and hemolytic anemia.” and I wanted people who read your comment to know that.

  • theBCnut

    I’m assuming she juices veggies and added one clove of garlic to the other veggies.

  • theBCnut

    She juiced 1 clove into a large container of juice, was what I understood. I could be wrong though.

  • theBCnut

    So you believe the amount of garlic in Blue Buffalo causes bloody diarrhea and pancreatitis? Or did I word my response so poorly that you think I mean garlic in any amount won’t cause any issues, because I meant in the amount the dog should have got from the food, but I realize after going back and rereading that I didn’t exactly say that.

  • Crazy4dogs

    Could the OP be using garlic juice? Would the make it too much of a dose?

  • Dori

    Not theBCnut but I notice the OP does not mention what the “fresh squeezed juice”. Sounds like she added one clove of garlic to the juice. For garlic to be effective, depending of course in what the intent is, the garlic needs to be minced, sliced thinly, or chopped and left to sit out for about 10 minutes before adding it to the dog food. Don’t know what the intent was in adding it to a large container of juice and she doesn’t mention what she did to the clove before hand. Possibly one dog got the whole clove? One whole clove is much too much for a 9 pound dog. I minced one clove and let it sit out for approx. 10 minutes or so and then add it to all three girls food bowls. I would never give them one entire clove to any of them minced or otherwise.

  • el doctor

    Garlic in large amounts may or may not cause “bloody diarrhea”, but it certainly HAS caused diarrhea without blood, hemolytic anemia, plus a host of other negative symptoms.

    “According to (Dr) Lee, symptoms of garlic toxicity include breathlessness, lethargy, diarrhea, vomiting, pale gums, an elevated heart rate, an increased respiratory rate, weakness, exercise intolerance, and collapse”

  • Crazy4dogs

    BCnut, I’m not that familar with garlic dosage. Should the OP be giving garlic juice?

  • theBCnut

    Um, NO! Garlic in large amounts MAY cause anemia, then again it may not. It certainly does NOT cause pancreatitis and bloody diarrhea. Good grief.

  • Dori

    Oh for goodness sakes. Garlic does not cause pancreatic issues and/or bloody diarrhea. Anything will cause issues in anyone if given in toxic levels. I’ve been giving my three toy dogs minced garlic at minimum daily in one of their meals for more years than I can remember with one and from day one with the other two and there has never been an issue of any sort. My Maltese is now 16 years old, Maltipoo and Yorkipoo were both 6 years old last June. Always check with your homeopathic or holistic vet and, yes, even your allopathic vet as to any supplements you may feel inclined to give a sick or immune compromised dog. Certainly if your dog already has an illness or prone to said illness some common sense in all matters should be taken but no, garlic in itself in correct moderation and dose does not cause pancreatitis or bloody diarrhea.

  • Karen Embry

    Garlic causes pancreatic issues in dogs…hence the bloody diarrhea.
    I just found garlic listed way down the list on our blue buffalo dog food I feed my yorkies. …im switching yoday!!!! My smaller one just had bloody diarrhea is better now……..that made me go look. Few months ago my 10 lb yorkie had it. Not taking anymore chances. I love them too much!

  • Anna Miller

    There are two great videos on this forum, but both conflicting a bit. What brought me here…I gave a fresh squized juice to 3 of my dogs, it was a garlic tooth added, it was a pretty big container of juice, but dogs got a very small amount of this. My Parti Yorkie about 9 pounds 1 y.o.got very sick and had to go to doctor. The blood test was ok, but the temperature was high and the liver fuction was a bit off. They did what ever procedures needed and kept the dog for two hours in clinic. The dog was just fine at night after the doctor’s, and played a lot. Next day she had loose poops with blood and felt reallly bad. I was on the edge to run to emergency, but after a long sleep and the walk she drunk some water and eat her dinner. Other two dogs feeling just fine, but they are a bit bigger. So I guess it is just an amount of garlic, depending on weight of your dogs. She had this juice before, but the garlic tooth was very small. Maybe alergies, or maybe some parasites, which poisoned her after garlic started to work. It could be a spider bite as well. I feel a bit better after reading this blog. Thanks for posting.

  • Deena Chavez

    I have a 6 month female purebreed siberian husky and a 9 yr old terrier mix, the vet has always thought she is boarder collie and american staf mix

  • Crazy4cats

    Hi Deena-
    I just wanted to let you know that I fed my dogs the Bug Off Garlic all summer and neither one of them got a single flea. They are 80lb labs who spent a lot of time outside. I only gave them about half the recommended amount. I also did, however, give them one application of Advantage the first of July to start off the season.
    I hesitate to recommend garlic because of the controversies, but for my house there were no side effects that I know of and no fleas!
    My sister’s dogs were covered and she only lives a couple miles away and her dogs aren’t outside much. She was using Frontline and it didn’t work.
    I also used fresh garlic a few times a week when my dogs had Giardia to help rid of the nasty parasite.
    Good luck on your decision.

  • DogFoodie

    You bet! Welcome!

    Garlic can be a difficult decision. You’ll read that there are many who are confident that garlic is safe and others who believe that it’s not safe, in any form or quantity.

    There are some breeds that are more susceptible to Heinz Body Anemia, such as Akitas and Shiba Inus. I’m not sure what that cute little fella is in your profile picture, but that’s something else to consider.

  • Deena Chavez

    Thank you so much for your help. Im new to this dogadvisor forum.

  • DogFoodie

    Hi Deena,

    There’s been lots of conversation in the forums about garlic and the use of Springtime’s Bug Off Garlic. Go here: http://www.dogfoodadvisor.com/forums/ and on the forum home page forum, type in Bug Off Garlic or garlic or fleas. I think you’ll find lots of information there. Springtime’s website under the additional information or studies tab has lots of useful links, too.

    It’s my understanding that BOG is safe, because it’s dehydrated and the concentration of allicin is significantly reduced.

  • Deena Chavez

    I have read some good things about Bug off garlic chewables for dogs. However Iam concerned about the whole dont feed garlic to dog thing. I would prefer to feed bug off garlic vs. the spot on med Im giving. Just looking for some reassurance that others have had no health problems with Bug off garlic. Im new to this holistic arena.

  • Dog_Obsessed

    There is a great site called dogaware.com that has some recipes. Make sure you are feeding a balanced diet if it is home cooked, don’t just feed some protein and carbs. Also, consider using a pre mix (complete diet except for meat.) such as The Honest Kitchen Preference or See Spot Live Longer.

  • Dylan Bradley

    I’ve been looking into home cooked meals for my most awesome buddy Brie. I’m looking into multiple sources to come to my conclusion on whats best for Brie.What I’ve been feeding her lately is ACANA (handful) steamed liver, peas, carrots, corn and brown rice, poached egg. sometimes boiled potato is added instead of rice. I’ll serve it warm. (warm food takes less energy to digest) I have been considering the benefits of garlic and found this article informative , so thanks to the author.

  • Kyburz Willowynd

    I’m with you on this Todd as I see garlic as the lesser potential evil as I stated above. And it may not even have an impact at all as not enough work has been done on this.

  • Kyburz Willowynd

    Thanks for the article. I appreciate the research. I don’t have anything really to add, but one thing that always disappoints me is the lack of funding that goes into alternative approaches. I think that our current health system – for pets and humans is highjacked by the pharmaceutical industry so that there is a huge bias toward research into these systems. I do give my dogs garlic tabs from Springtime Naturals and it works to control fleas and I believe likely ticks and potentially mosquitoes. I’m just not comfortable using spot on treatments. I do worry about the health impacts as you have stated some real potential impacts. It just seems like we have to try to choose between the lesser of a known toxin (spot on treatments for fleas and ticks and pills for heartworm) and a potential problem with garlic. But garlic does seem to work for us as a preventative measure. And we do have fleas in California.

  • Todd Van Every

    I’ll take my chances with garlic and garlic and brewers yeast as there 100% natural and digestible.
    Lets see what is in a heart worm prevention pill and the chemical property’s and frontline plus if it kills fleas in 5 minutes or less what does it do for the dog’s skin and etc…cancer!!!!!! We have 3 dogs a mountain cur full blood, a black mouth cur redbone coonhound mix, and a full blood nova Scotia duck tolling retriever with all heartworm and flea tick negative

  • Dog_Obsessed

    This is a great article, it clearly identifies the possible benefits and possible risks of garlic in pet food without a bias. Nice job Dr. Mike!
