Have your dog stand with their forelimbs on a bowl and their hindlimbs on a half step. Use a treat and your body to encourage them to step one hindlimb off the side of the half step. You may need to gently shift their hip over to encourage them to side step off. Reward this and then reposition and step off with the alternate hindlimbs. They should then repeat with alternating hindlimbs for the prescribed number of reps by your therapist.
