I was just wandering. Is fish food bad for dogs?? Twice now my family and I have gone out and we have come back and our giant tub of fish was gone and partly on my dogs face. So we bought another one thinking he was just hungry when we went out. We left and came back and the exact same thing happened except his time he ate the bottle two. So now we put it under our sink where he can't get to it. But my point/question is. Is fish food bad for dogs??
