when you ad more than one dog into your house the hierarchy has to change, or at least is upset. The only time i have been able to bring a inside dog into the house when there is another adult canine already living there is if the new dog is a puppy then the older dog can bitch down the puppy without blood being drawn.
I am no expert on it though so this is only my experiences, the time it worked was with a young female pit and the older a female roc. I had tried other time when i found a dog in an unfortunate situations but the older roc would not back down and there was always a bad experience
