I really believe it is something with the particular mix of shep and rottie. They are actually more common than I had ever imagined and I have yet spoken to anyone who has one or that knows someone who has one and when they describe them I'd swear it sounds like they are talking about Herc.

Hercules really likes to jump. I always tell him he thinks he's a reindeer. He acts like one day he just might take off!

Both of my dogs love to run but thier reasons are different. Hercules likes to play fetch and Zeus likes to chase Hercules while he's playing fetch.
