Welcome to YT! I think everyone is right about him being abused...I had a Golden that was loved from day one-no one every hit or even attempted to..He stayed outside during the day, and one day I was playing ball with him raised my hand to throw the ball and he hunker(sp) down...he has never done that before, long story short, my neighbor had been hitting him in the head to get his ball from him...needless to say my neighbor doesn't come near me now..(he is very afraid too/for go reason)..What I am trying to say is Hunter was never abuse at home but a couple of times someone hitting him made him start acting that way...
