Dog Food Ingredients

The dog food ingredients in the food you give your Boston directly affect the quality of the food as well as his health. The following guide will help you determine the general quality of your current brand of commercial dog food.

How to grade your dog's food:

Start with a score of 100:

1. For every listing of "by-product", subtract 10 points
2. For every non-specific animal source ("meat" or "poultry", meat, meal or fat) reference, subtract 10 points
3. If the dog food ingredients include BHA, BHT, or ethoxyquin, subtract 10 points
4. For every grain "mill run" or non-specific grain source, subtract 5 points
5. If the same grain ingredient is used 2 or more times in the first five ingredients (i.e. "ground brown rice", "brewers rice", "rice flour" are all the same grain), subtract 5 points
6. If the protein sources are not meat meal and there are less than 2 meats in the top 3 ingredients, subtract 3 points
7. If it contains any artificial colorants, subtract 3 points
8. If it contains ground corn or whole grain corn, subtract 3 points
9. If corn is listed in the top 5 ingredients, subtract 2 more points
10. If the dog food ingredients include any animal fat other than fish oil, subtract 2 points
11. If lamb is the only animal protein source (unless your dog is allergic to other protein sources), subtract 2 points
12. If it contains soy or soybeans, subtract 2 points
13. If it contains wheat (unless you know that your dog isnÂ’t allergic to wheat), subtract 2 points
14. If it contains beef (unless you know that your dog isnÂ’t allergic to beef), subtract 1 point
15. If the dog food ingredients include salt, subtract 1 point
