This thing has done this since release. I think it is the only one that has this type of Idle animation (animations like that one dog that tries to dig through the stone floors in a bank for instance)
I just put it down to my job as the owner of the pet is to make sure it always has a place to run to.
Enjoy the game, life is what you really want to be worried about.

That glitch happens when a scuttler tries to turn around. When I stand still and switch two different pets (a dog and the scuttler) dog walks up to me and then turns around but when I spawn the scuttler pet he walks up to me and starts running in place pointing the way the dog would.
