Hi, I was wondering if anyone could help me with this. I have a seven month old APBT who is, like most Pit Bulls, very friendly. In fact, he's a little too friendly. He does not jump up on me, or mouth me and IF he does once I tell him "off" or "no" he stops. However, when he meets new people, he constantly jumps all over them and mouths their hands. He is so excited to see these people, that he doesn't listen to me and he definitely does not listen to them. He even does this while we're walking outside, he just jumps up on random people. Any suggestions would be greatly appreciated. Thanks! Oh, btw, he knows all basic commands and then some.
