Glad your pup is okay. Dog's can take a load of punishment some times and just seem to ignore it and get on with their activites.
I grew up in Kentucky and although I never owned treeing hounds, my grandfather always did. I never got a chance to hunt coons or foxes with them, but I've heard them running at night. Truly amazing how those dogs love to hunt.
I have hunted a lot of rabbits with beagles and that is fun albeit on a smaller scale. Once I hunted a wild boar and although the outfitter had a couple of black and tans, the best hunting dog of them all was a little beagle that just turned up at the outfitters house one day. The little dog was wild as a coyote, and according to the outfitter, no one could touch him (even the outfitter) without the dog biting you!
He sure had the heart of a hunter, though.
