I think you did okay. You took immediate action and you got an appropriate response. Think about it, though. He had his head in the trash when you smacked him the first time and he didn't know what hit him. He turned around to defend himself, teeth bared. He didn't know it was you. It was a natural reaction on his part, really. It could have been one of the other dogs. He didn't know. But you smacked him on the nose and the butt and you probably yelled at him, too, and he backed off. That's as it should be. It's all good. And now he's subdued. I think he's waiting to know if he's forgiven. If he knows any commands at all, like Come or Sit, you might call him to you, Bandit Come, then Sit. Then praise him for obeying, just a simple Good Boy, and a pat on the head, then he'll know he's forgiven and you still love him. That will put an end to it. Really, he didn't attack you, he just defended himself.
