I watched it last night also. Those scenes where the dogs were fighting was, like other's have said, hard to watch.
I think it's so....sad that @ lst he said he didn't have anything to do with that and once all the evidence showed he did, then & only then did he say he was part of it.
I was so happy to see that they were able to get mostly all the dogs into homes as pets after working with them.
I think the show is being shown again on Wednesday night on Animal Planet.
