I have recieved dogs in rescue like that & we have been able to always change them. Of coarse I tell my husband never to yell, even just yelling for me in the other room & I would hold the dog for security as he petted it several times then let it down & give her/him a treat, eventually they would take a treat from my husband, and they would have time alone, next thing they are sitting on his lap. But one yell for your favorite team, one quick move can set you back. Its really sad.
If he is WILLING to earn her trust he can
