Your right, I will retract it and say most, mostly including the not so grand brands. I don't think people need to get uptight and defensive about it. What you feed your dogs is what you feed your dogs. But the true plain god given fact is that dogs are 99.8% related to wolves and they can breed with wolves. Obviously their systems can't be that different. Before dog food, there have been dogs eating roadkill and table scraps.

This is what I'm going to be doing for a living. I don't think I would give anyone false information. I LIVE for this stuff.

Oh and actually there are many different answers to the pH of human stomachs. Lots of places say less than 4, 1-2, 2-3, 3-4. Most places say dogs are 1... possibly 2. And there really isn't an argument against the shortness because dogs are meant to eat meat (not trying to convert anyone. One of my dogs still eats kibble... she lives with the grandparents... long story. But I really hate it when people think I'm trying to convert them)
