Aussie Attacking Other Dogs And My Fiancee
We have had our Aussie for a little over three years now and he has never shown any kind of aggression at all towards anyone or anything. About a month ago my fiancee was walking him while I was at work and he randomly attacked a Maltese that was walking with her owner, he brought him home and put him up with our other dog who he then attacked, then after breaking up the fight and separating them he tried to attack my fiancee. We haven't had an incident since then until now. We have had our dogs separated since but today Kane, the Aussie, got out of his crate and attacked our Pit Bull. I don't know what to do. I really don't want to lose my dog.
