When Remy came home from the breeder's house he was on puppy chow. After keeping him on that until he got acclimated to our home we switched him to Nutro ultra. The Nutro totally messed with his stomach... after having him on it a month we changed foods again (to Pro Plan) because his stools were not at all solid while on Nutro. Now he's on Pro Plan LBP and loves it... gobbles it up so fast that we had to buy one of those metal balls to make him eat slower. His stools are perfect. However, he has gas everyday and it is the worst smelling gas I've ever experienced. It smells worse than rotting meat... and I'm not joking. I know some gas is normal but if he has gas this often should I try to switch his food again?
