I can post some pics of my pits when I get home. And again, I'm not claiming to be an all knowing pit man. I've had a few that caught hogs for me. I don't breed them, couldn't come up with a popular bloodlines name if my life depended on it. I have catchdogs to catch hogs, just so happens I had pits up until recently. What bloodlines, who were their parents, what was their history, I couldn't tell you. They caught pigs, so I fed them in return. Did I need them to be fast and agile, no. I needed them to run 30 yards and catch a pig. If for whatever reason they didn't catch, I put them back on the atv and carried them to the next bay. Could they catch a big hog? Yes, and they did it extremely well for me over the years. I felt very safe walking into a caught hog, knowing those two pits were locked on. They were very well behaved and I've never, ever carried a break stick. Every pit I've ever owned came off the hog by verbal commands.
Someone asked if I thought the ABs were faster than pits and I gave my opinion based on the dogs I've owned.
My male pit was as tall and leggy as an AB, but he couldn't out run my daughters overweight weenie dog.

In his mind, he probably thought he was a grayhound, but we'd laugh so hard watching him try to run with the other dogs in the backyard. It was comical and always a good laugh.
I didn't intend this post as a bashing of pits, quite the contary. I loved my pits, but for me, I felt it was time to go in a different direction.
