Our new Silkey, Lacey, has a bit of a problem. When around people she knows, she is a sweetheart, and loves to cuddle. There is only one problem. She HATES men. I've seen her on two occasions growl, bark, and basically go crazy when a man has entered the house. First incident was when my friend Joel came over and Lacey began growling and barking at him and all he'd done is walk through the door. We know it had to be on the basis that he was a guy because Lacey didn't bark at my friend Rose who came with him. The other occasion happened rather recently. My uncle came over and Lacey actually bit him and broke the skin. She doesn't do this to anyone else but men. We think she may have been abused by a man, since she has absolutely no aggression towards women. This morning, however, my grandmother says that Lacey attacked our Yorkie, Haley, and actually went for the throat, so I don't know about that. Any suggestions?
