Scientists !!

I have never done any tests with commercially available dog food, but I'll throw my two cents in here. I think a complete raw diet is the absolute best for a dog.

I fed my German Shepherds a complete raw diet for years, until my buddy lost his job at the packing plant, and I lost my good prices. The dogs coats looked great, the dogs never smelled "doggy", and they were full of energy. And as far as stools, I wouldnt hardly know. Never cleaned them up. These dogs roamed my yard, not in a kennel, and after 3-4 days, the poo would turn to a white powder and pretty much disappear. I never once scooped poo when I was feeding raw. I was feeding two dogs, almost 3lbs of food a piece, and while I had a good price hook up it didnt cost me much more than some top of the line dog foods. Unfortunately I lost my good price hookup and couldnt find another and it just got too expensive to feed raw.

After that I started feeding Innova EVO, which is supposed to be the best substitute to a raw diet. But it was costing just as much as feeding raw, and while the dogs still looked great and were full of energy, their stools wouldnt disappear like before. It was at this point that I began to look for a cheaper food. Tried a few of the supposed higher quality ones claiming to mimic a raw diet, but eventually settled on the Diamond sporting dog formula. For the cost difference, I couldnt tell too much difference between it and some more expensive feeds.

I now have two potential hog dogs that I am raising, and they are eating the Diamond as well. No loose stools, no hard stools, and the dogs look good. I imagine there are better feeds out there, but not too many in the same price range that are available around here. I read a lot on here about Black Gold and Outlaw and some others, but cant find any in my area. I would be interested in trying some of those if I could find them, but for now that is what I have so its what I use.
