So, today at lunch, I went home to play with Porter and he was chasing his tail like a crazy man. He'd catch it and like knaw on it, never biting or anything. Then, I caught a glimpse of some fleshy looking thing on the bottom side, near the end. I took a pic with my phone so it's not great, but you can see what I mean. It's not bleeding or anything. Just looks like flesh. Could this be the way all boxers tails are, or is it a botched bob-job, or what?
