The suggestion is that the next time you play, take something similar to a stick in one hand, such as beating a massage stick or even chopsticks, and hide it. When you play with it with your other hand, it will bite you. You should immediately hit its ass with the stick in your other hand, say no and whisper. Knock hard, but don't hurt it

Don't hit the dog with your hands, because you usually play with it and give it something to eat with your hands. If you hit it again, it will think you are playing with it and will be disobedient. Dogs are afraid of sticks. Even if you use chopsticks, they will remember why you play chopsticks.

Repeat this several times, it will remember, and it will bite next time. . . But I won't bite you. Actually, it's playing you again.

Also, educate dogs, especially those who beat dogs, on the spot. If they make a mistake, educate them if they are caught red-handed, and they will know where they are wrong. If you hit them again afterwards, they won't know where they are wrong at all.
