Any! You are not really bothered.

"Well," the man says nervously, "most of the other dogs that are worth using are busy at the moment. But there is King."
"King?" you ask, puzzled. The man grins and informs you that King is a male Rottweiler. He's apparently very aggressive though.
"Like some of the larger animals, but unlike most of the dogs, once you enter King's cage, you're his 'subject.'" the man informs you. "Nobody is going to go in there to help you, and he's not going to let you leave until he's satisfied with you. Hell, he kept one girl in there for three days, fucking her ragged. All we could do was slip her food and water when we fed King."
"Whoa, that's pretty horrible." you think, as you notice the man chuckling. He then went on to explain that the girl is now King's only visitor, at least once a month. This kind of excites you even more, but you're not sure. You bite your lower lip, trying to decide.
