The first ingredient in this dog food is whitefish, a protein-rich freshwater species native to Canada and the northern United States.
The second ingredient is fish broth. Broths are of only modest nutritional value. Yet because they add both flavor and moisture to a dog food, they are a common addition component in many canned products.
The third ingredient is salmon, another quality raw item. Salmon is a fatty marine and freshwater fish not only high in protein but also omega 3 fatty acids, essential oils needed by every dog to sustain life.
The fourth ingredient is potato. Potatoes can be considered a gluten-free source of digestible carbohydrates. Yet with the exception of perhaps their caloric content, potatoes are of only modest nutritional value to a dog.
The fifth ingredient is herring. Nutritionally, herring is very similar to salmon.
The sixth ingredient includes carrots. Carrots are rich in beta-carotene, minerals and dietary fiber.
The seventh ingredient is sweet potato. Sweet potatoes are a gluten-free source of complex carbohydrates in a dog food. They are naturally rich in dietary fiber and beta carotene.
The eighth ingredient is guar gum, a gelling or thickening agent found in many wet pet foods. Refined from dehusked guar beans, guar gum can add a notable amount of dietary fiber to any product.
The ninth ingredient is sunflower oil. Sunflower oil is nutritionally similar to safflower oil. Since these oils are high in omega-6 fatty acids and contain no omega-3’s, they’re considered less nutritious than canola or flaxseed oils.
Sunflower oil is notable for its resistance to heat damage during cooking.
There are several different types of sunflower oil, some better than others. Without knowing more, it’s impossible to judge the quality of this 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 three notable exceptions…
First, garlic can be a controversial item. Although many favor the ingredient for its claimed health benefits, garlic has been linked to Heinz body anemia in dogs.1
So, one must weigh the potential benefits of feeding garlic against its proven tendency to cause subclinical damage to the red blood cells of the animal.
Next, carrageenan is a gelatin-like thickening agent extracted from seaweed. Although carrageenan has been used as a food additive for hundreds of years, there appears to be some recent controversy regarding its long term biological safety.
And lastly, this food contains chelated minerals… minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.
Drs. Foster and Smith Adult Canned Dog Food
The Bottom Line
Judging by its ingredients alone, Drs. Foster and Smith Adult canned dog food looks like an above-average wet product.
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 46%, a fat level of 21% and an estimated carbohydrate content of 26%.
As a group, the brand features an average protein content of 44% and a mean fat level of 28%. Together, these figures suggest a carbohydrate content of 20% for the overall product line.
And a fat-to-protein ratio of about 64%.
Above-average protein. Above-average fat. And below-average carbs when compared to a typical wet dog food.
Free of any plant-based protein boosters, this looks like the profile of a wet food containing a significant amount of meat.
Doctors Foster and Smith Adult is a meat-based canned dog food using a significant amount of named meats as its main sources of animal protein, thus earning the brand 5 stars.
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.
