Using a treadmill to exercise your Thai Ridgeback will allow it to exert some energy, especially in the cold months of the year when you cannot take it for a long walk.
Step 1.
Use a treat to lure the puppy to step on the treadmill as you guide him forward if he is not sure. Use a command as you place your hand to touch the surface to show the puppy it is safe to step on. Reward with a treat and lots of physical praise when the puppy climbs up and walks up and down the belt. Prevent the puppy from jumping down. Instead, use a release command to allow him to leave the treadmill. Repeat 2 to 4 times.
Step 2.
Desensitize the puppy from the sound of the running belt by turning the treadmill on. Observe puppy's reaction. If he is indifferent to it, turn up the speed to make it louder. Always reward a calm response.
Step 3.
Tether the puppy near the treadmill and turn on the belt. Begin walking and running (if you do) and observe puppy's reaction. Avoid talking to the puppy if it looks worried and reward if it looks indifferent to the sound of the running belt with you moving on it. If puppy looks scared and wants to run away, stop and return to the Step 2 by repeating it until better result.
