Red items when present indicate controversial ingredients
The first ingredient in this dog food is whitefish… a protein-rich freshwater species native to Canada and the northern United States.
Whitefish is naturally rich in the ten essential amino acids required by a dog to sustain life.
The second item is fish broth. Broths are nutritionally “empty”. But because they add moisture to a dog food they are a common finding 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, fiber and is also (unlike many other grains) gluten-free.
The fourth item is oat bran… a nutritious by-product obtained by 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 spinach. Spinach is an excellent source of vitamins and numerous minerals.
The sixth ingredient mentions peas. Peas are a quality source of carbohydrates. Plus (like all legumes) they’re rich in natural fiber.
What’s more, peas contain about 25% protein which must be considered when evaluating the total protein reported in this food.
Cassia gum is a plant extract used here as a gelling agent. Cassia gum provides no nutritional value to this food.
The eighth ingredient is carrageenan… another gel-like thickening agent extracted from seaweed. Carrageenan has been safely used as a food additive for hundreds of years.
The ninth item lists guar gum… one more gelling additive 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 next items include three nutrient-rich fruits and vegetables…
- Tomatoes
- Apples
- Blueberries
We also find flaxseed… 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.
Sunflower oil is high in linoleic acid… an essential omega-6 fatty acid needed by every dog to sustain life.
But the ratio of omega-6 to omega-3 fats in a food is nutritionally critical… and can vary significantly (depending on the quality of the source ingredient itself).
There are several different types of sunflower oil… some better than others. Without knowing more, it is impossible to judge the quality of this ingredient.
We also note 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.
Blue Buffalo Longevity Canned Dog Food
The Bottom Line
Judging by its ingredients alone, Blue Buffalo Longevity looks to be an above-average canned dog food.
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 36X%, a fat level of 18% and estimated carbohydrates of about 37%.
As a group, the brand features an average protein content of 36% and a mean fat level of 18%. Together, these figures suggest a carbohydrate content of 37% for the overall product line.
Near-average protein. Below-average fat. And above-average carbohydrates when compared to a typical canned dog food.
Even allowing for the protein-boosting effect of the peas, this looks like the profile of a wet food containing a moderate amount of meat.
Bottom line?
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 four stars.
Highly recommended.
