Gosh, that sucks. I was hoping you could keep her with you. He sounds like a crappy dog owner. If she was truly happy she wouldn't keep running to your house. If it happens again dye her coat and keep her. Be sure and change her collar also. What a jerk. He should want was is best for her. Poor Baby, she is so cute. Maybe it is time to call animal control or the spca, sounds like abuse to me, someone must be able to help.
