Jack Russell Terrier’s First Day on the Treadmill

This was Sophie's first day on the treadmill after a progression of introductory steps. (Up commands onto a stationary treadmill, supporting her body midway while the treadmill ran slowly, and finally, starting the treadmill while having her on a loose leash.) She now recognizes the command/question “treadmill?” and hops onto it eagerly and no longer needs the leash.
