Is there a way to curb reaction aggression?
I have a 9-year-old, large, mixed breed dog who gets along well with other dogs except if we have a dog who picks a fight, he doesn't back down. Our other dog, about 1 year old, has had dogs go after her due to dominance and toy aggression, and she just backs away quickly and avoids a fight. Is there any way to encourage this behavior in our older dog? It comes up so rarely that I'm not sure how I would go about curbing it, but I figured I would ask. Is this a sign of a larger issue? He's generally a very well-mannered, chill dog, and we get compliments on him alllll the time.
