Purina Dog Chow Review

I have dogs allergic to wheat and it is tough to find a cheap food without wheat. I was going thru a tough spot in life and couldn't afford much to feed my four dogs. I was pleased to see Purina Dog Chow didn't have too horrible of ingredients. Now, mind you, I am not a fan of by=products or corn but had to draw the line somewhere. Now three of my dogs are losing their hair! One has gone completely bald on his stomach and tail and another one has flaky bald patches all over his back. I've switched them on to Canidae now and in a week there is improvements. Not happy with Purina at all.
