I've been feeding chicken feet for at least three years. That was one thing I thought I'd never - ever - in a million years feed my dogs! They still weird me out! LOL But, I know they are a natural source for glucosamine and chondroiton, so I do it. My Mo still has some bad days w/arthritis, especially in wet cold weather; but, nothing like when he was eight. Before we switched to RAW, he was dragging his left(?) hindquarter.
I am so blessed to have a natural a petfood store just down the road. She carries chicken feet and green tripe. You might have to order green tripe.
Here is a site, but I can't vouche for the quality, as I don't use them.
