Aggressive Mtn. Cur
Our 3 yr old female, Mtn. Cur, named Copper suddenly and viciously attacked a 12 yr old female Australian Shepard, who she knows. The Aussie is a growler and has been noisily aggressive in the past with our dog.
But Copper was the aggressor this time and drew blood. Copper had to be physically pulled off the old Aussie. It happened twice within a span of a two day visit by her owners.
Very scary situation for all. What could have caused our dog to go ballastic and can we turn that unacceptable behavior around?
Copper has never shown aggression with any other dogs but we are concerned that something has changed.
