Using two blocks or boxes (about elbow height), place the 2 front feet on one block & one rear foot on the other block, whilst leaving the other rear leg on the ground. Now, slowly take the ‘grounded’ leg off the ground by sliding it backwards until it is not in contact with the floor anymore. This should make your dog straighten the rear leg that is on the block. Then place your hand UNDER the foot you slid off the ground, or grasp around the hock, and push the dogs rear end towards the airborne foot and slowly lower that foot to the ground again.
