Boss of the treadmill
One of my foster dogs, Heidi, tries to get in front of Tiger on the treadmill. Watch his fancy footwork as he puts her in her place. Tiger eventually squeezed Heidi all the way to the little space on his left, where she stayed for the rest of the session.
By the way, Miss Buttinski Heidi is available for adoption at http://www.yorkierescueme.com/ourdogs.asp and Mugsy the poodle is available at: http://www.petfinder.com/petdetail/20906323?rvp=1
