I hunted with the Fatty dog around 10 years ago when Bill Hobson first bought him. He was a pretty impressive dog... as we were tying, he was baying another one. I think we caught 8 that morning, one right after the other.
He was bred to several dogs in East Texas and produced some very good dogs. Findahog on here may correct me if i'm wrong, but I think his buddy Drue had some Fatty/Parker crosses that were the real deal.
