Oddly, I’ve found that pit bulls won’t wrap themselves around a tree. We’ve had several in our house that are/were walked daily, and we volunteer at a dog shelter where my wife and I walk other pit bulls on a regular basis. There are exceptions, but my experience is that the vast majority will not let anything (like a tree) between themselves and their handler if on leash. Just when I think “ah, ha! You’re going to do it…”, they will course correct and go around to avoid trouble. It’s the oddest thing. I have never come up with a plausible theory, but it sure is nice.

(And it is not our dog handling, as our control groups are happy to wrap circles around a tree.)
