The first ingredient in this dog food is lamb. Lamb is considered “the clean flesh derived from slaughtered” lamb and associated with skeletal muscle or the muscle tissues of the tongue, diaphragm, heart or esophagus.2
Lamb is naturally rich in all ten essential amino acids required by a dog to sustain life.
The second ingredient is lamb liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.
The third ingredient is lamb broth. Broths are of only modest nutritional value. Yet because they add both flavor and moisture to a dog food, they are a common component in many canned products.
The fourth ingredient is brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.
The fifth ingredient is herring. Herring is a fatty marine fish naturally high in protein as well as omega 3 fatty acids, essential oils needed by every dog to sustain life.
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 dog food. They are naturally rich in dietary fiber and beta carotene.
The eighth 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.
The ninth 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.
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, 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.
Next, 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.3
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.
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 Review
Judging by its ingredients alone, Drs. Foster and Smith Adult Canned Dog Food looks like an above-average wet product.
The dashboard displays a dry matter protein reading of 41%, a fat level of 32% and an estimated carbohydrate content of 19%.
As a group, the brand features an average protein content of 43% and a mean fat level of 32%. Together, these figures suggest a carbohydrate content of 17% for the overall product line.
And a fat-to-protein ratio of about 74%.
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.
However, with 56% of the total calories in our example coming from fat versus just 30% from protein, some recipes may not be suitable for every animal. In addition, this same finding also prevents us from awarding the brand a higher rating.
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 4.5 stars.
