Australian Shepherd Showing Sudden Aggression Toward Other Animals
(Columbia, South Carolina)
My 6 (almost 7)-year-old Australian Shepherd in the past 3 weeks has started attacking our other animals. Twice our cat and just today our 15-year-old mutt.
We have an appointment with the vet but I’m not sure if it’s because my parents got divorced and my dad who always took care of her moved out, so she’s living with my mom who she’s not super bonded to.
She also was the kind of dog who would let herself out of our back yard and wander to neighbors' houses and go play with their dogs without any issues.
Any insight would help.
