Although I don't have dogs, I too wouldn't be able to live with dogs that didn't get along and could potentially hurt/kill each other. I actually had to rehome one of my cats,Cirrus, because he and Storm would fight daily and over time the fights got worse. I had to do something before they really hurt each other and since Storm was there first Cirrus had to go.

Cirrus also started trying to attack Sky who is the mellowist cat in the world. He only seemed to like Sunny. I found out later that all of his siblings were doing the same thing. They all were alpha cats. They needed to be only cats or in a place with a lot of room so they could be away from the other cats. Cirrus was adopted by a wonderful lady and he had a much better life with her than he could've had with me. Now both he and Sunny have been reunited again because they're both up at the Rainbow Bridge.
