Dog Food Rating Scale
This is an example of a well thought through dog food rating scale. As with any "scale," the attributes are assembled by someone who has an opinion on what is good and bad, but we feel that this one makes a great deal of good sense. This scale also rates some of the more common foods using the criteria provided as an example. We feel that this scale is intelligently thought out, and the rating criteria used match up very closely with much of what the literature on premium canine nutrition has to say on the topic. You can use this scale as a general "evaluation" tool when deciding what type of food to provide for your Cane Corso, Rottweiler, or other Working Breed. This is not our own scale, it is reprinted from a posting we once saw on a bulletin board.
Canine Food Rating Scale and Criteria
Start with a grade of 100:
-
For every listing of "by-product", subtract 10 points
-
For every non-specific animal source ("meat" or "poultry", meat meal or fat) reference,
subtract 10 points
-
If the food contains BHA, BHT, or ethoxyquin, subtract 10 points
-
For every grain "mill run" or non-specific grain source, subtract 5 points
-
If the same grain ingredient is used two or more times in the first five ingredients
(i.e. "ground brown rice", "brewer's rice", "rice flour" are all the same grain), subtract 5 points
-
If the protein sources are not meat meal and there are less than two meats in the top
three ingredients, subtract 3 points
-
If it contains any artificial colorants, subtract 3 points
-
If it contains ground corn or whole grain corn, subtract 3 points
-
If corn is listed in the top five ingredients, subtract 2 more points
-
If the food contains any animal fat other than fish oil, subtract 2 points
-
If lamb is the only animal protein source (unless your dog is allergic to other protein
sources), subtract 2 points
-
If it contains soy or soybeans, subtract 2 points
-
If it contains wheat (unless you know that your dog isn't allergic to wheat), subtract 2 points
