I have 2 labradoodles 3 and 3 1/2. They have been together their whole lives. Recently after a trip to the dog groomer, the dominant one has been attacking the submissive one to the point where they cannot be together anymore. Before that attack, nothing had been different in the environment or with their behavior. I went to the groomer to see if anything occurred and they said nothing happened. I'm now stuck because the submissive one is petrified of the dominant one. I've tried to reintroduce them to each other on leashes with muzzles, covering them in baby powder to change their scent, being in the same vicinity but on leashes - but nothing seems to be working. I want them to get along but i feel like they will never again. I'm looking for some advice or if anyone has experienced this before.
