A simple way to rate a dog food

This isn’t the way I rate dog food, but it’s an interesting method and seems to work pretty well. I found it in the deep dark depths of a forum for Miniature Horses of all places. It’s worth trying out if you wish to substantiate any of the reviews on Pet Food Ratings (or if it’s a food we haven’t reviewed)!

Personally I’d have more prominent weightings for a number of ingredients (i.e. I’d subtract more points for wheat and soy beans), so it’s always worth researching a food as much as you can from other websites, forums, vets, and other professionals.

Let’s have a look…

Start Points

Start with a grade of 100.

Negative Points

Subtract points based on the following:

Contains by-products -10
Every reference of non-specific animal source (“meat”, “poultry”, meat, meal, or fat) -10 (per reference)
Any reference on BHA, BHT, or Ethoxyquin -10
Every reference of grain “mill run” or non-specific grain source -5
Same grain used 2 or more times in the first five ingredients (i.e. “ground brown rice”, “brewer’s rice”, “rice flour” are all the same grain) -5
If protein sources aren’t a meat “meal” and there are less than 2 meats in the top 3 ingredients -3
Contains artificial colors -3
Contains ground corn or whole grain corn -3
Corn is listed in the top 5 ingredients -3
Contains any animal fat (except fish oil) -2
If lamb is the only protein source (unless your dog is allergic to other protein sources) -2
Contains soy or soybeans -2
Contains wheat (unless you know your dog isn’t allergic to wheat) -2
Contains beef (unless you know your dog isn’t allergic to beef) -1
Contains salt -1

Positive Points

Now add points based on the following:

Any organic meat sources +5
Endorsed by any major breed group or nutritionist +5
Food is baked not extruded +5
Contains probiotics +3
Contains fruit +3
Contains vegetables (NOT corn or other grains) +3
Animal sources are hormone-free and antibiotic free +2
Contains barley +2
Contains flax-seed oil (not just the seeds) +2
Contains oats or oatmeal +1
Contains sunflower oil +1
For each different specific animal protein source (other than the first one; count “chicken” and “chicken meal” as one protein source) +1 (per reference)
Contains glucosamine and chondroitin +1
If vegetables have been tested for pesticides and are pesticide-free +1

Final Grading

You can now rate the food based on the following grading system:

A 94-100+
B 86 to 93
C 78 to 85
D 70 to 77
F (FAIL!) Less than 70
