The first ingredient in this dog food is pork meat and bone meal, a dry “rendered product from (pork) tissues, including bone, exclusive of any added blood, hair, hoof, horn, hide trimmings, manure, stomach and rumen contents”.1
Pork and bone meal may have a lower digestibility than most other meat meals.
Scientists believe this decreased protein quality may be due to the ingredient’s higher ash and lower essential amino acid content.2
On the brighter side, pork and bone meals are meat concentrates and contain nearly 300% more protein than fresh pork.
The second ingredient 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 third ingredient is wheat flour, a highly-refined product of wheat milling. Like corn, wheat is an inexpensive and controversial cereal grain of only modest nutritional value to a dog.
For this reason, we do not consider wheat a preferred component in any dog food.
The fourth ingredient is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.
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 fifth ingredient is 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).
The sixth ingredient is beet pulp. Beet pulp is a controversial ingredient, a high fiber by-product of sugar beet processing.
Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.
We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most dog foods is entirely acceptable.
The seventh ingredient is poultry digest. A digest is a chemically hydrolyzed brew of slaughterhouse waste. Animal digests are usually sprayed onto the surface of a dry dog food to improve its taste.
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, we note the inclusion of dried egg product, a dehydrated form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that have failed to hatch.
In any case, eggs are easy to digest and have an exceptionally high biological value.
Next, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
In addition, 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.
And lastly, this recipe includes 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.
Blue Seal Classics Dog Food
The Bottom Line
Judging by its ingredients alone, Blue Seal Classics looks like a below-average dry 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.
As a group, the brand features an average protein content of 27% and a mean fat level of 13%. Together, these figures suggest a carbohydrate content of 53% for the overall product line.
And a fat-to-protein ratio of about 47%.
Near-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the corn gluten meal, this looks like the profile of a kibble containing a moderate amount of meat.
Blue Seal Classics is a plant-based dry dog food using a moderate amount of named meats as its main sources of animal protein, thus earning the brand 3 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.
