How is Major with food in general? Does he show aggression, growl, give you "that look" if you or another animal approaches his bowl? I worked on this with Star since puppyhood, hand feeding her, then putting my hand in her bowl when she ate, lifting it and taking it away, making her sit then giving it back and so on. I worked hard too on the "leave it" command and if she ever accidentally bit my hand while playing rough, I'd pull my hand away, look upset and say loudly "ouch, NO BITE!" It worked great and to this day, she and Cody can eat together out of the smallest dish and she never will try and take Cody's bone, food etc. I'd try working hard with a rawhide, offering it to him, holding onto it, then taking it away, giving the "leave it" command. Make him sit then offer it again, take it away, and so on. Do it again and again and again. He'll get the idea. And do that with his other toys, his food, etc. He has to know that you can give it and you can take it away, anytime! You might also check out the "Nothing in Life is Free" dog behavior program. I hear people have great results with it! Maybe someone has a link; more info!
