He's really good about it. There have only been two dogs that he didn't like, and they were both male bully breed mixes. They were also both very bouncy and pushy. So I'm not sure if it's the male factor, the bully factor, or the personality factor. But he's been really sweet with most of the fosters, especially the little ones.debs said:Buster is a good boy. He seems to love all if not most of the fosters you briong home.
