We're still having a problem with Scooter being obsessive about everything we eat. When we eat anywhere around him, or even if he thinks we are eating something, he barks and screams and squeals and tries to get at the food. He gets plenty of his own food and we refuse to give him "people food". We have tried ignoring him, and also correcting him by growling "no", scruff shakes, crates and leash corrections.... and none of it has worked at all. In fact it's getting much worse... Any suggestions?
