Some dogs will compete over anything, including being first on 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.

Miss Buttinski Heidi is available for adoption and so is Mugsy the poodle.

Witness the tale of one tireless slinky that never gave up and almost made it to the bottom of the treadmill.

A puggle (pug and beagle mix) has figured out how to use the treadmill,  that it’s owner has made it walk on, with the minimum amount of effort. Why use 4 legs when you can use two?
