Some of my research has already been done for me by others. Most of the questions in the AAHA commercial dog food selection guidelines have already been submitted to various dog food companies, and the answers to these questions collected in one place:
Pet Food Company Survey
The companies surveyed include: Blue Buffalo, Canidae, Acana/Orijen, Eukanuba, Fromm, Nature's Variety, Innova/EVO, Wellness, and Royal Canin. Of these, Royal Canin stood head and shoulders above all the rest, but many of the others gave good responses as well. For a raw food company, I was impressed that Nature's Variety has gone through the AAFCO feeding trials for their raw foods. Kudos to Nature's Variety. Fromm gave a dodgy response, and Primal wasn't asked. I'll let you know what I hear back from Primal...
