Red items when present indicate controversial ingredients
The first ingredient in this dog food is corn. Now, contrary to what you may have heard, corn isn’t necessarily a bad ingredient.
On the other hand, although there’s no way to know from the list entry itself, the corn used in making many pet foods can be similar to the kind used to make feed for livestock.
And that can sometimes be problematic.
What’s more, corn is commonly linked to canine food allergies1.
For these reasons, we rarely consider corn a preferred component in any dog food.
The second ingredient includes meat meal… “the rendered product from mammal tissues, exclusive of blood, hair, hoof, horn, hide trimmings, manure, stomach and rumen contents except in such amounts as may occur unavoidably in good processing practices”.2
Since in this case the source animal is not known, this meat can come from anywhere. Road kill, dead zoo animals, diseased or dying livestock… even euthanized cats and dogs.
On the brighter side, however, meat meals are meat concentrates and contain nearly 300% more protein than fresh meat.
Although this item does contain all the amino acids a dog needs, we do not consider meat meal a quality component.
The third ingredient is wheat. Wheat is another problematic grain and subject to the same issues as corn (previously discussed).
The fourth ingredient is soybean meal. Soybean meal is actually a useful by-product. It’s what remains of soybeans after all the oil has been removed.
Soybean meal contains 48% protein. However, compared to meat, this item is considered an inferior plant-based protein providing a lower biological value.
The fifth ingredient is chicken fat. Chicken fat is obtained from rendering chicken… a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.
Chicken fat is high in linoleic acid… an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.
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 two notable exceptions…
First, we find no mention of probiotics… friendly bacteria applied to the surface of the kibble after processing.
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.
Sportmix Dog Food
The Bottom Line
Judging by its ingredients alone, Sportmix Dog Food appears to be a below-average kibble.
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 24%, a fat level of 9% and estimated carbohydrates of about 59%.
As a group, the brand features an average protein content of 27% and a mean fat level of 11%. Together, these figures suggest a carbohydrate content of 54% for the overall product line.
Below-average protein. Below-average fat. And above-average carbohydrates when compared to a typical dry dog food.
In addition, when you consider the protein-boosting effect of the soy meal, this looks like the profile of a kibble containing only a moderate amount of meat.
Bottom line?
Sportmix Dog Food is a plant-based kibble using only a moderate amount of chicken or meat meals as its main sources of animal protein… thus earning the brand two stars.
Not recommended.
