four! The dogs are all in the houses! We recently visited the one with four and I hated being there the whole time. The dogs were totally out of control and climbing on everything, including us. The dogs can easily get out of the back years through holes in the fence. I am just waiting for the day when one of the dogs, or all of them, go off on someone.
I fully support litigation when a pit bull bites anyone, and putting the dog down.
