There are two different methods to teaching your dog this trick. If your dog can already give his paw on command, start by having him sit in front of you, and ask for his paw.
Grasp his paw in your hand, and then raise it over his eyes. Repeat the command gently, and treat him immediately.
Continue repeating the process until your dog makes the connection. Another way to teach this trick is by using a small piece of scotch tape.
Have your dog sit in front of you, and then stick a small piece of tape or a yellow post-it note to the end of his nose. Ensure the tape is not too strong or he will have trouble removing it. Wait for your dog to raise his paw to remove the tape.
As soon as your dog lifts his paw to his nose, praise him, and administer a treat. Continue with the tape until he begins to understand the command. Next, try simply tapping your dog’s nose gently to get him to raise his paw. If you repeat these steps whilst saying the command, your dog will eventually perform the trick automatically.
