Son doesn't walk HAS fed many and been 1 on 1 when I'm at work or away. When he was younger son APPEARED a little hesitant but not now the dog just doesn't appear to like him but he gets into the play but follows my son with his deep bark.  Dog is also great with everyone I took him around everywhere when I first got him as a pup.  Butch. my dog doesn't act that way with ANYONE except my son.
