Ok, thanks everyone, I will try some of the things you've been telling me. I already am on the NILIF thing.

I'm still teaching Major "drop it". He won't sit, have something in his mouth, and drop it. I have to hold on and then say it, but at least he's got that down so far.

I've never seen Major give me "that look". I pet him while he eats sometimes. Another animal hasn't ever approached his bowl while he was eating. I think he'd just eat quicker though. Oh, and before I give him his food, I ALWAYS make him give me his both paws (I'm trying to teach him Sit Pretty...so far not working lol) and then shake, other, and down and sit. Then he gets his food.

I'm pretty sure the growl was real, it sounded pretty mean.

Thanks everyone, from what you've all said, I have some better images in my mind of what to work on/do when it happens, etc.
