Pet Food: Calculate Your Food’s Grade

A natural, healthy diet for your pet is paramount to his or her long term health. It pays to be an educated consumer and review the ingredients of the food you feed your pooch. It is also very good to rotate among well-rated pet foods for variety.

An additional good resource is this link below where it allows you to compare ingredients from various foods side by side: http://www.naturapet.com/tools/comparison.asp.

Start with a grade of 100:

  1. For every listing of “by-product”, subtract 10 points
  2. For every non-specific animal source (“meat” or “poultry” meal or fat) reference, subtract 10 points
  3. If the food contains 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 named meat or meat meals (ie: chicken, turkey, etc) and there are fewer 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 food contains any animal fat other than fish oil, subtract 2 points
  11. If lamb is the only animal protein source (unless your pet 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 pet is not allergic to wheat), subtract 2 points
  14. If it contains beef (unless you know that your pet is not allergic to beef), subtract 1 point
  15. If it contains salt, subtract 1 point

Extra Credit:

  1. If any of the meat sources are organic, add 5 points
  2. If the food is endorsed by any major breed group or nutritionist, add 5 pointsx
  3. If the food is baked not extruded, add 5 points
  4. If the food contains probiotics, add 3 points
  5. If the food contains fruit, add 3 points
  6. If the food contains vegetables (NOT corn or other grains), add 3 points
  7. If the animal sources are hormone-free and antibiotic-free, add 2 points
  8. If the food contains barley, add 2 points
  9. If the food contains flax seed oil (not just the seeds), add 2 points
  10. If the food contains oats or oatmeal, add 1 point
  11. If the food contains sunflower oil, add 1 point
  12. For every different specific animal protein source (other than the first one; count “chicken” and “chicken meal” as only one protein source, but “chicken” and “turkey”, etc as 2 different sources), add 1 point
  13. If it contains glucosamine and chondroitin, add 1 point
  14. If the vegetables have been tested for pesticides and are pesticide-free, add 1 point
