The first ingredient in this dog food includes whitefish, a marine or freshwater species native to Canada and the California coast.
The second ingredient is fish broth. Broths are nutritionally empty. But 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 oatmeal, a whole-grain product made from coarsely ground oats. Oatmeal is naturally rich in B-vitamins, dietary fiber and can be (depending upon its level of purity) gluten-free.
The fourth ingredient is oat bran, a nutritious by-product obtained from milling whole grain oats. The bran is the fiber-rich outer layer of the grain containing starch, protein, vitamins and minerals.
The fifth ingredient is peas. Peas are a quality source of carbohydrates. And like all legumes, they’re rich in natural fiber.
However, peas contain about 25% protein, a factor that must be considered when judging the meat content of this dog food.
The sixth 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 seventh ingredient is 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.
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 four notable exceptions…
First, 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.
Next, fish oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids. These two high quality fats boast the highest bio-availability to dogs and humans.
Depending on its level of freshness and purity, fish oil should be considered a commendable addition.
In addition, flaxseed 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.
However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.
And lastly, this food also 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.
Blue Buffalo Longevity Canned Dog Food
The Bottom Line
Judging by its ingredients alone, Blue Buffalo Longevity 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.
As a group, the brand features an average protein content of 36% and a mean fat level of 19%. Together, these figures suggest a carbohydrate content of 37% for the overall product line.
And a fat-to-protein ratio of about 52%.
Below-average protein. Below-average fat. And above-average carbs when compared to a typical wet dog food.
When you consider the protein-boosting effect of the peas and flaxseed, this looks like the profile of a wet product containing a moderate amount of meat.
Blue Buffalo Longevity is a meat-based canned dog food using a moderate amount of whitefish as its main source of animal protein, thus earning the brand 4 stars.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content.
