My fiancé has an Aussie that is extremely aggressive towards me and has bit her multiple times and lunged at me multiple times. He has been fixed and is still extremely aggressive mainly towards me. I do not know if he senses I’m the alpha or what. The dog has destroyed our new home and I’m lucky enough to be able to take my senior chocolate to my dispatch and he will hang out with my dispatchers while I’m on shift(I’m in law enforcement). If I left them alone I’m worried he would get hurt. I know some aussies can be this way as guy on my shift got attacked by one years back. Is this really that normal or are these just the exceptions??
