Awwww I'm so sorry.. I know how hard it is to lose a dog due to the dogs not getting along. I had a deaf aussie/bc mix that thought Megan was a chew toy and she'd grab Megan by the tail and drag her around and then she also started fights with my oldest dog Miksy. She was too much for my family Luckily, she found a good home though. I'm sorry Misty started ganging up on Shadow.. but I'm sure Shadow will find a new, wonderful home.
