Well she did hurt him, but it wasn't like he was torn to pieces. He does have some marks, on him, but they aren't deep or anything. We put some anti septic on, and if they don't look good tomorrow he'll have to go to the vet I guess.
She wasn't trying to put him on his back, she just sort of grabbed him and held him. I only got her off by pulling on her choker chain, because her jaws are way to strong to try open yourself.
I'm quite sure that if she had wanted to she could have killed him, because she's very big and her mouth could fit around his whole neck. Still, it is a very worrying sign because she was definitely doing more than warning him. The food wasn't even on the ground yet, we where on the way outside with it, and the little dog fell off of where he was sitting, and she just turned and grabbed him. The little dogs get fed inside, and her outside, to try keep them seperate because I know she won't appreciate them being around.
