The first ingredient in this 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 soybean meal. Soybean meal is relatively useful by-product — what remains of soybeans after all the oil has been removed.
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 third ingredient is poultry by-product meal, a dry rendered product of slaughterhouse waste. It’s made from what’s left of slaughtered poultry after all the prime cuts have been removed.
In a nutshell, poultry by-products are those unsavory and inedible leftovers deemed “unfit for human consumption”.
In addition to organs (the nourishing part), this stuff can contain almost anything — feet, beaks, undeveloped eggs — anything except quality skeletal muscle (real meat).
We consider poultry by-products slightly lower in quality than a single-species ingredient (like chicken by-products).
On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh poultry.
The fourth ingredient is wheat middlings, commonly known as “wheat mill run”. Though it may sound wholesome, wheat mill run is actually an inexpensive by-product of cereal grain processing.
In reality, wheat middlings are nothing more than milling dust and floor sweepings — and an ingredient more typically found in the lower quality pet foods.
The fifth ingredient lists poultry fat. Poultry fat is obtained from rendering, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.
Poultry fat is high in linoleic acid, an omega-6 fatty acid essential for life.
However, poultry fat is a relatively generic ingredient and can be considered lower in quality than a similar item from a named source animal (like chicken fat).
What’s worse, this fat is preserved with BHA, a suspected cancer-causing agent.
After the natural flavors, we find chicken meal, another protein-rich meat concentrate.
The eighth ingredient is brewers dried yeast. 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.
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, flaxseed meal is one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also rich in soluble fiber.
Next, we note the minerals listed here do not look to be chelated. And that can make them more difficult to absorb. Non-chelated minerals are usually associated with lower quality dog foods.
And lastly, this Tuffy’s Dog Food product contains menadione, a controversial form of vitamin K linked to liver toxicity, allergies and the abnormal break-down of red blood cells.
Since vitamin K isn’t required by AAFCO in either of its dog food nutrient profiles, we question the use of this substance in any canine formulation.
Tuffy’s Dog Food
The Bottom Line
Judging by its ingredients alone, Tuffy’s 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.
As a group, the brand features an average protein content of 28% and a mean fat level of 15%. Together, these figures suggest a carbohydrate content of 49% for the overall product line.
Near-average protein. Near-average fat. And near-average carbs when compared to a typical dry dog food.
In addition, when you consider the plant-based protein-boosting effect of the soybean meal and brewers yeast, this looks like the profile of a kibble containing only a modest amount of meat.
Tuffy’s Dog Food is a plant-based kibble using a limited amount of poultry by-product meal as its main source of animal protein, thus earning the brand 1 star.
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.
