This method of grading dog food was developed by Sarah Irick. It is not to be considered exact science but a starting point for people who need help with how to read labels and choose a good food. She has provided the grading scheme, foods that have already been graded in alphabetical order, and dog foods that have been graded in order of score.

 

Guidelines

  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 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 two or more times in the first five ingredients (i.e. “ground brown rice,” “brewer’s rice” and “rice flour” are all the same grain), subtract 5 points.
  6. If the protein sources are not meat meal and there are less than two meats in the top three 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 five 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 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 isn’t allergic to wheat), subtract 2 points.
  14. If it contains beef (unless you know that your dog isn’t 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 points.
  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 “fish” 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.

Meet the Person Who Developed This Method

My name is Sarah Irick and I am a Great Dane owner and rescue volunteer. I am a Civil/Industrial Engineer, not a veterinarian or animal nutritionist by education or employment. I do not work for a pet food manufacturer nor am I affiliated with one. I am just an individual who is concerned about what I feed my dogs and want to help others decide what to feed their own. I cannot remember the exact date I designed this system. I was concerned with the way people sometimes throw out names of “good” dog foods that maybe aren’t so good, and others take their words for it. Foods that maybe used to be good before their ingredients were changed for the worse or before better options became available are still being touted by some as being super-premium and I disagree. Since many pet owners do not have the time or inclination to do as many hours of research into pet (specifically dog) nutrition as I and many of you have, I wanted an *easier* way for them to compare labels. Unfortunately it is still a bit cumbersome (sometimes two people calculate the same food and end up with different scores) but it’s better than nothing in my opinion.
