Creature the Boston Terrier is not the first puppy we've seen to bounce around for kicks -- this little dog seems so happy leaping across a concrete warehouse rabbit-style. According to veterinarian Bruce Tannenbaum, Creature's hopping gait "isn't normal by any means" -- but that doesn't necessarily mean it's a problem. "The way this dog hops could be an adaptation to some sort of muscular issue, or it could be neurological," Tannenbaum said. "But he's clearly learned to work around it. If you look at humans walk or run, you'll see that we all do it differently -- that's what's going on here. He's just running a little differently."
