1. First, let the dog sit down in front of you, hold the bait in your right hand, and place it close to the ground. Say "shake hand" to your dog while encouraging him to reach for your hand with his paw. Once the dog's left paw leaves the ground, reward it with food.

2. Slowly raise your hand and guide the dog to extend its paws to chest height.

3. Transition to using gestures. Stand up, holding the bait in your left hand behind your back, and extend your right hand when giving the "handshake" command. When your dog catches your hand, hold its paw in mid-air and reward it with the bait.

4. Use the same steps to train the dog's right paw, using the "extend paw" command.

Possible difficulties:

Some dogs may not grab the owner’s hand, but sniff with their nose. What should I do?

Solution: Tap the dog’s nose to stop it. The dog may bark, nuzzle you, or simply remain motionless. Be patient and keep encouraging it. If the dog cannot lift its paw on its own, pat it gently or help it lift it, and then reward it.

If the dog does the action you want, immediately say "you are awesome" to confirm its performance, and you can also reward it with small snacks.
