Puppies will do it on occasion. They're saying "This is MINE, and you can't have it." What they have to understand is it may be theirs, but YOU can take anytime you want to. If Major should get something that could harm him, and you need to take it away you need to not be afraid to do it.

I was watching animal cops the other day on Animal Planet and they had rescued this shep x, who had a collar embedded in his neck. Sweet , sweet dog. Until they fed him and did the agression test. They put the food down and used a rubber manaquin hand. He put holes in that hand! If it had been a human, they would have lost a finger or two. Because he was food aggressive, he was put down.

I know Major isn't THAT bad, but with something like that you need to be sure you nip it in the bud before it turns into something worse.
