I have 4 yorkies. Allie 8, Mollie 7, Lacie 7 and Sophie 1 year old. Sophie is constantly jumping Allie and attaching her. She bites her ears and breaks skin. Allie is afraid of her and I have to keep her on the bed, couch etc. so that Sophie will not hurt her. The other 2 Yorkies will fight her off so Sophie does not mess with them, but poor Allie is so afraid. Because of the situation Sophie has her own kennel and the other 3 stay together in another. I had hoped that they all would able to be together eventually. I do not want to get rid of Sophie but I don't know how to stop the agression. Does anyone have any suggestions? Help!
