Jack was mistreated by a man (or men) and children apparently, in a previous life. He now has an adorable, fantastic lady as his caring owner, who is sweet and has been giving him a good life back... He's still a little scared of children but is a good guy.
@nicknac thank you Nick. One day I'll get a shot of him retrieving the ball his owner throws, he's wonderfully happy when she does that! Happy animals make me happy. :)
