Well, I once met a Beagle that would throw his head up, wag his tail and Kick that back leg like CRAZY DOGS do if you ruffly scratched a certain spot on his back near his tail. It was just a coincidence that this tri-colered beagle had a big, black spot right there that just plain said; SCRATCH ME HERE! SCRATCH ME HERE! (LOL everyone, it's true!) and I'll never forget that little guy.
