Does this hair of the dog have any type of protein in it? Pippen can't really handle too much of the stuff. His poo starts to smell real bad. That leads me to believe his system can't handle it. I give him Lambs meal, and it seems to have helped with his food allergies. But I worry about giving him things I don't know much about. I tried him on this product called Missing Link. It was said to be great for hair and skin problems. His system didn’t get along with it. Nor did our cats and our other dog. So I have stopped using said product. Some one mentioned on another site to use bicarbonate of soda. But I don't know what that is, or where to get it. Or if it really works, this person said it would help it heal fast.
