Have your dog touch your hand with his or her nose; reward with a treat. You can do this by holding the hand close to your dog’s nose, but under the chin, palm up. You can also rub the scent of the treat on the open hand to entice your dog to touch it. Repeat this process for 1 to 2 minutes each day until the behavior sticks.
Note: Some dogs will pick up these steps more quickly than others. It may take a few hours, a few days or even a few weeks depending on your pup.
