Raw what, though? Any tips, Backwoodsman?

It might be a puppy thing. My painted puppy farts like Big Bertha; my late and deeply lamented old girl never farted at all; she was 15/16ths border collie, the rest labrador. The only real difference is that he's a blue-eyed merle; I hope the farting doesn't suggest something wrong inside, since merles are a genetic sport.
