I've seen it all, I have a bitch that kept on getting skin irritations. I fed her the same thing I feed all of my dogs tgthe natures variety venison and lamb raw boost, she kept on getting skin irritations, changed to duck, lamb chicken, rabbit, bison... Nothing... Kept on getting skin irritations. The limited ingredients fish and sweet potato had the least irritations, but it still broke her out. Finally, deboned raw chicken, and she really broke out. I was just about to give up and put her down as a an antibacterial wash twice a week was getting on my nerves. My girlfriend said, maybe she's allergic to meat. I told her it was impossible, dogs evolved from wolves, wolves were hunters that ate meat. Anyway, I left to a wedding in the north Georgia mountains, she went to tbe pet store WITHOUT my permission and fed vegan Natural Balance dog food and I got back today and the coat is perfectly clean and the foul oder is gone! WTF??? Anyway, I've spent the last hour contemplating how this is possible. And voila... Could it possibly be that since victor aycart fed his dogs dried corn for the last 7 years that they evolved and adapted to it? I don't know.. But it's racking my brain.
