Help! Aggressive 10 Year Old Australian Shepherd
My girl will be 11 years old in November. For the past year she has been getting very angry and trying to bite my husband and I. This behavior does not seem to have one particular thing that brings it on.
Sometimes we can just be petting her and she will start growling, barking and try to bite us. This breaks my heart because I do not know what is causing her to be this way.
Does anyone have a suggestion as to why my loving dog is suddenly becoming very aggressive towards us?
