Once your dog is familiar with the treadmill while it's turned off, allow her to interact with it while it's running.  Use the treadmill on the lowest possible speed in front of your dog.

As you continue to make your dog use the treadmill, gradually speed up the intensity of the workout.  Once your dog is comfortable on the treadmill for 1 minute, build up to...
