1. The training method is: have the dog wear a collar and command it to lie down on your left side. Hold the leash with your left hand as a necessary training tool besides the toy.

　　2. Hold the toy with your right hand and slowly pull it away from the dog's sight, starting close and moving farther. The dog will crawl forward slowly to reach the toy, while you can use your left hand holding the leash to assist the dog's forward crawling.

　　3. If the dog raises its hips too high during crawling, gently place your hand on the dog's hips, then guide by pressing or lightly tapping to help lower the hips.

　　4. If the dog completes crawling without raising its hips, give the toy as a reward.

　　5. After the dog finishes the action, besides giving the toy as a reward, don't forget to immediately give treats as encouragement.
