Well see we just got him...we rescued him. I don't actually know what kind of training he had before. But i do know that when we got him he wasn't very...i don't know, respectful. He got into the garbage got on the furniture [[he has his own chair lol]], he didn't listen at all. But now he is very good! I also know that when there is another dog around, he just goes right at them he doesn't even give them a chance to sniff or anything. I don't know if this was the kind of information that your looking for but I hope it helped!!!
