A few good tools to use when choosing dog food:
The first one came from several posts by BoxMeIn21...
http://www.dogfoodanalysis.com/
This next bit was found by CaptBob and seems pretty accurate:
This is a dog food rating system created to help people find a quality food. This is not concrete but to be used as a guide. This was created by Fredalina of the GDR.
Giving Dry Dog Food a Grade:
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 2 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 2 meats in the top 3 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 5 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
If it contains beef (unless you know that your dog isn’t allergic to beef), subtract 1 point
If it contains salt, subtract 1 point
Extra Credit:
If any of the meat sources are organic, add 5 points
If the food is endorsed by any major breed group or nutritionist, add 5 points
If the food is baked not extruded, add 5 points
If the food contains probiotics, add 3 points
If the food contains fruit, add 3 points
If the food contains vegetables (NOT corn or other grains), add 3 points
If the animal sources are hormone-free and antibiotic-free, add 2 points
If the food contains barley, add 2 points
If the food contains flax seed oil (not just the seeds), add 2 points
If the food contains oats or oatmeal, add 1 point
If the food contains sunflower oil, add 1 point
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" as 2 different sources), add 1 point
If it contains glucosamine and chondroitin, add 1 point
If the vegetables have been tested for pesticides and are pesticide-free, add 1 point
94-100+ = A
86-93 = B
78-85 = C
70-77 = D
