What type of food are you guys feeding your dog. I was on Pedagree for about 3 years and feed my gsp coffee can a day. I now use Black Gold which is high in protien meat, not corn and he eats 3 cups a day. Sounds like they can't get enough to eat because corn base meal won't digest properly and that stuff just goes right through them. I am now feeding less and when they eat less, they crap less and they digest and use more of the eating product. Just wondering what type of food, you may wan't to check that out.
