I have a bully x, and she's a great dog. But she's a one person dog. She will acknowledge DP, as she has been on the scene for over ten years but I'm her master. And she won't play with any other animals, so socialising with other dogs is out of the question. She was chasing fully grown rottweilers off the beach at 12 weeks of age! I love my dog, but hate being constantly on the lookout for other animals when out for a walk. If another dog comes close, she'll bristle and then most likely attack. If that other dog come at her quickly and barking, then it's all on. Then again I have 2 cats and she doesn't do more than sniff them.
