Anyone have a suggestion for a trainer in the chandler area? My friend got a 3 month old German Shepard out of a bad situation and she is now 11 months old.. She has attacked her golden retriever several times for no reason. At first it was play and then the other day they were just walking and the shepherd went after the other dog and the other dog defended herself and then her other mellow shepherd jumped in. My poor friend has been bit several times breaking this up and after this last fight she was injured again.. She is very knowledgable with dogs but needs help to figure out what is triggering the fights. They do not eat together she took all tug of war toys away.. She needs a trainer to help her or she has to rehome the shepherd. She only goes after the female dog. All dogs are fixed as well. Thanks!!
