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 item lists 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 quality skeletal muscle (real meat).

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 includes 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.

Compared to meat, glutens are inferior grain-based proteins lower in some of the essential amino acids dogs need for life.

This inexpensive plant-based ingredient can significantly 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 seventh ingredient is 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.

After the chicken flavor, we find salt (also known as sodium chloride). Salt is a common additive in many dog foods. That’s because sodium is a necessary mineral for all animals — including humans.

However, since the actual amount of salt added to this recipe isn’t disclosed on the list of ingredients, it’s impossible to judge the nutritional value of this item.

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 three notable exceptions

First, 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%.

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 effects 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 Dog Food is a plant-based kibble 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.

Special Alert

Rice ingredients can sometimes contain arsenic. Until the US FDA establishes safe upper levels for arsenic content, pet owners may wish to limit the total amount of rice fed in a dog's daily diet.

    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.

  • InkedMarie

    Never heard of it but I googled. Unless I did something wrong, you have one formula. I’ll pass

    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.

    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! ;-)
