Estimated Nutrient Content
Guaranteed Analysis21%10%NA
Dry Matter Basis23%11%58%
Calorie Weighted Basis22%25%53%
Protein = 22% | Fat = 25% | Carbs = 53%

The first ingredient in this dog food is corn. Corn is an inexpensive and controversial cereal grain. And aside from its energy content, this grain is of only modest nutritional value to a dog.

For this reason, we do not consider corn a preferred component in any dog food.

The second ingredient is chicken by-product meal, a dry rendered product of slaughterhouse waste. It’s made from what’s left of a slaughtered chicken after all the prime cuts have been removed.

In addition to organs (the nourishing part), this stuff can contain almost anything — feet, beaks, undeveloped eggs — anything except feathers.

On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh chicken.

In any case, although this item contains all the amino acids a dog needs, we consider chicken by-products an inexpensive, lower quality ingredient.

The third ingredient is soybean meal, a by-product of soybean oil production more commonly found in farm animal feeds.

Although soybean meal contains 48% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.

The fourth ingredient is animal fat. Animal fat is a generic by-product of rendering, the same high-temperature process used to make meat meals.

Since there’s no mention of a specific animal, this item could come from almost anywhere: roadkill, spoiled supermarket meat, dead, diseased or dying cattle — even euthanized pets.

For this reason, we do not consider generic animal fat a quality ingredient.

The fifth ingredient is chicken. Although it is a quality item, raw chicken contains about 80% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.

After processing, this item would probably account for a smaller part of the total content of the finished product.

The sixth ingredient is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.

Although corn gluten meal contains 60% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.

After the chicken flavor, we find beet pulp. Beet pulp is a controversial ingredient, a high fiber by-product of sugar beet processing.

Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.

We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most dog foods is entirely acceptable.

The ninth ingredient is calcium carbonate, likely used here as a dietary mineral supplement.

From here, the list goes on to include a number of other items.

But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this product.

With five notable exceptions

First, brewers yeast can be a controversial item. Although it’s a by-product of the beer making process, this ingredient is rich in minerals and other healthy nutrients.

Fans believe yeast repels fleas and supports the immune system.

Critics argue yeast ingredients can be linked to allergies. This may be true, but (like all allergies) only if your particular dog is allergic to the yeast itself.

In addition, a vocal minority insists yeast can increase the risk of developing the life-threatening condition known as bloat. However, this is a claim we’ve not been able to scientifically verify.

In any case, unless your dog is specifically allergic to it, yeast can still be considered a nutritious additive.

What’s more noteworthy here is that brewers yeast contains about 48% protein, a factor that must be considered when judging the actual meat content of this dog food.

Next, we find apple pomace, which includes the pulpy solids that remain after pressing apples to extract the juice. It is most likely used here for its fiber content.

In addition, we note the inclusion of dried peas. Dried peas are a good source of carbohydrates. Plus they’re naturally rich in dietary fiber.

However, dried peas contain about 27% protein, a factor that must be considered when judging the meat content of this dog food.

Next, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.

And lastly, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Non-chelated minerals are usually associated with lower quality dog foods.

Iams So Good Dog Food
The Bottom Line

Judging by its ingredients alone, Iams So Good looks like a below-average dry dog food.

But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.

The dashboard displays a dry matter protein reading of 23%, a fat level of 11% and estimated carbohydrates of about 58%.

As a group, the brand features an average protein content of 23% and a mean fat level of 11%. Together, these figures suggest a carbohydrate content of 58% for the overall product line.

And a fat-to-protein ratio of about 48%.

Below-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.

When you consider the protein-boosting effect of the soybean and corn gluten meals and dried peas, this looks like the profile of a kibble containing a limited amount of meat.

Bottom line?

Iams So Good is a plant-based dry dog food using a limited amount of chicken by-product meal as its main source of animal protein, thus earning the brand 2 stars.

Not recommended.

Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.

    Hey Eli, these are some of the foods I use that won’t break the bank, and are decent quality. 4health (Tractor Supply) Pure Balance, and Rachael Ray Zero Grain (Walmart) Nature’s Domain, and Kirkland (Costco) Victor dog food, you have to get Victor at a pet or farm/fleet store but it’s really good if you can get it locally. Here’s their site. They have a store locator. victordogfood.com

  • Eli Argueta

    Bruh i bought my dogs IAMS thinking it was going to do them good and and they would finally have good quality dog food, seeing as the other dog foods ive bought them were just as bad as this one. My pitbull got such a horrible reaction to this food that he started losing so much hair! like wtf man

  • Dori

    Jewels. I’m glad I was able to help and explain it in a way that is easy to understand. It’s a little scary at first because the old way of thinking used to be that when you transitioned to a different food and dog had diarrhea we were taught to believe that OH NO! This food is bad for my dog, I’ll stop and keep him on the same one. Then get nervous as to what to do next. Just do each transition to a new food very slowly. If your dog starts getting very soft stools then back up a little to where you were transitioning without the soft stool diarrhea and keep it there for a few days until your dog gets accustomed to the new food. Then start adding a little more each day while removing a little of his old. Some dogs initially can transition in 7 – 10 days. Some dogs can take a month to transition. The longer a dog has been on “crappy” food, the longer the transition takes because his gut has been so compromised that it takes a bit to heal. Transition the same way from bag to bag (if kibble is what you’re feeding). Some people rotate with each new bag, some rotate every 2 or 3 months. Eventually when you’ve done this long enough you won’t even need the transitioning of foods. Your dogs gut will heal nicely and be able to handle whatever you feed him/her. I’ve been feeding commercial raw and rotating for a couple of years or more and I can now rotate from meal to meal. I have one dog (Katie-lots of food allergies and intolerances) that does best if I give her a different food with different protein for every single meal. If I give her the same food twice in a day (I feed a.m. and p.m.) she’ll start scratching like crazy. Good Luck. Keep us posted as to your dogs progress and PLEASE ask as many questions as you want to. We’ve all been where you are right now and are all here to help each other out. Before I came onto this site I was feeding the same dry food day in day out. I’ve learned so much on this site from all the seasoned knowledgeable posters.

  • Jewels LaFleche

    Thank you so much for getting IT ..This is awesome ..Great advice on rotating foods makes total sense hearing it but would never have thought to do so was scared of change I guess .Thanks agian Dori.

  • LabsRawesome

    You’re Welcome. 🙂

  • Dori

    Hi Jewels. I would also tell you please please do not shoot yourself. A lot of us have been in exactly your same situation. I cannot recommend a specific food for you because I feed my three dogs raw but what I would advise you to do regardless of what you feed is not to feed the food you are feeding and to please go grain free. Dogs do not need grains of any sort. Yes, there are so many foods that it is overwhelming to pick a food. Look at the reviews on this site, choose from the 3, 4 and 5 star reviews. Choose grain free and try one of the foods. Once you find a food that your dog does okay with then start looking for another food to transition your dog to, then do it again, and again. Most of us on this site believe that rotating foods is the ideal way to feed our dogs for many reasons. Good Luck

  • Jewels LaFleche

    I can’t thank you enough for your advice it’s been rough… I think I will indeed switch to wet food since we got Flapjack the 12lb wonder dog 🙂 he has always eaten Dry food thats what the breeder had recommend to me but I like your thoughts on the matter and agree its time for a change
    so thanks agian …..

  • LabsRawesome

    Don’t shoot yourself! We have all fed crap foods in the past, because we just didn’t know any better. Since you have a Rat Terrier, I would suggest you feed her canned food. Canned is much better for the dog than kibble. There are some very good 4 and 5 star brands that are budget friendly. Costco’s Nature’s Domain Turkey and Pea Stew $20 for a case of 24 cans. Walmart’s Pure Balance canned $1 per can or $1.25 for the grain free. And Tractor Supply has 4health canned for .99 cents per can. 🙂

  • Jewels LaFleche

    I have the urge to shoot myself after reading this ….My dogs health has suffered from using this Brand of Iams I can see that for sure in fact I have no plans to fed him anymore of it or to ever buy any Iams brand Product again I feel so over whelmed by the products out there and there claimed of being healthy ..My little Rat Terrier is dealing with yeast issues right now and I thought Diet needed to change maybe ,Well now I’m sure of it ….

    This site is highly nmanipulatedb.When you say someting against their favorate companies for instance Nature Logic or orijin then you find yoru posts eather

    officially deletedn or magically dissappeared a few days later. Only the devotees posts will remain.When you say someting about uuu

    their nheigh proteinn diets who are proven nwrong then they will bullyn,flag,nblock and ndelete you in order to

    promote their subversivenn angenda.i have to write this way otherwise I end up in nspamn.They misrepresentedb the bstudies

    and then when you point out the ndangers their own nstudies have shown they will delete your posts making up stories.

    They construe textbooks for instance claiming the textbooks state you can give 40 or 50% knprotein to a senior dog

    while they say 28% max. then they use nstudies sponsored by pharmacytical companies or purina to falsely substantiate their claims.

    when you point out the flawsn then your posts will dissappearn. Nshawnna will lie pretty much about anything to

    promote her 50% nprotein dietnn. For instance falsely claiming her dog is not on medication or those dogs would not live very long

    while it would not be unusual if the dog is still alive. Then she keeps contradicting herself how much knprotein she feeds

    depending on the arguments.check out the web under nscammn about more information.

    100s of people have been nbulliedn and blockedn on here. Vetsn get regularly blockedn and their posts deletedn. Mnike the ndentist

    is not an expert yet him among the devoteesnn without any credentials make so many false claims but think they know it all.

    Please don’t buy into their highnnnproteinn meatmnn based dietn it is all not nessessarly superior, also don’t believe their

    exchagerated claims on lentils,ngluten,nntomatoes,nraw food etc.

    Buyer Beware!

  • divawro .

    I’m guilty i went to tesco and bought it- only because we are having some financial issues this month and i thought it should make no harm until next wages- it was mistake- and product can go to the bin- my dog was vomiting for 3 days with this food- he actually didn’t digest it (he ate it in the evening and everything was out next morning). Well, yes, he does have more than normal sensitivity to changes and i didn’t just give him this food- it was mixed with his usual food. Anyway he’s not really interested in touching it

    I just can’t consider Brown Rice,
    Ground Grain Sorghum, Dried Plain Beet Pulp, Oat Groats,
    Brewers Dried Yeast, Natural Flavor,
    Whole Ground Flaxseed, Lecithin, and Canola Oil to be the best ingredient either.

    I am the owner of Enve Pet Food and you could not be more right. We put the best ingredients on the inside of the bag, not the outside.

  • Melissaandcrew

    If it gave both dogs stomach/intestinal issues, she should try to return it in case there is something wrong with it.

  • Pitmomma

    Don’t throw it away, give it to your local animal shelter, they will utilize it!

  • Pattyvaughn

    BB is everywhere.

  • Hound Dog Mom

    Probably Nutro, I’ve been seeing quite a bit of their commercials recently. Also Fresh Pet.

  • Kikki

    That’s what I’ve always thought. Talk about being shocked when I started seeing Wellness commericals a few month’s back. Have seen another “higher quality brand” aside from Wellbess but can’t remember which atm.

  • mary

    Iams is famous for its cruel animal testing. Not only it does not provide any valuable food, but also it causes plenty of animals to suffer immensly.

  • LabsRawesome

    Seeing a commercial for a food should be a red flag. Good manufacturers use their money for ingredients, not advertising. 🙂

  • Storm’s Mom

    Yup, but hopefully others like you who have seen the commercial will do the same thing: come on here, learn the truth, and steer clear of this product 🙂

  • Kenneth Cypret

    I saw a commercial for this stuff. Seemed to play of recent Blue Buffalo commercials as far as tone and wholesome message strongly implying that So Good is premium dog food. My initial thought was “good for Iams for stepping up their game.”

    So just out of curiosity I hit up Dog Food Adviser to check out Iams’ claims. While technically true it doesn’t have sugar or dyes, I am disappointed that this is just another below average corn kibble.

  • Michael M

    It gave both of my dogs diarrhea. I bought a huge bag so now I’m out $24 as I need to throw it out. 🙁

  • Annie

    I priced this food at my local wal mart and it’s $12.97 for 13.5lbs. Crazy

  • Pattyvaughn

    Probably a picture of a cute dog on the bag. Not much else.

  • LabsRawesome

    Really? What’s So Good about it? Absolutely nothing. Lol.

  • Pattyvaughn

    They could use that in their advertising! 😉

  • Well it’s better than the competition Be Happy!
