As for other people taking Vegas, not if I'm the area. He's mine and is gonna stay right with me. Even before I had him broke to stay with me off leash. I like that in some ways though, loyalty. He's ok if they take him one way and I go another though. I'm sure he don't mind them like he does me though.
Vegas is enjoyable to watch. As far as listen to me! Not. May as well be speaking Chinese. He is good for me on a leash, but listen not so much.
