I'm not sure if I saw the pictures you were talking about? Which ones made you think they might be fighting their dogs? It really doesn't look like they are fighting the dogs. A lot of people do use the ropes so the pits can swing off them. I have never done it with Ebony though. One of those dogs looked a lot like Ebony.

Those ropes are called swing poles. They look like they are breeding for size, so many of the pit breeders these days are breeding for huge heads, it's nuts. Some of them are going for 34 inch heads. Who knows if they are good breeders or not? So many people breed pits when they have no business doing it.
