I used this method. My dog used to get so rough that I was concerned that he was going to hurt someone.

Adding to it, when play stopped, I turned away and ‘sulked’ because body language means so much. Also, I added in a toy for tug of war, and whenever the play escaped the toy I said ow and play was done.

This took a few months to really sink in for the dog, but we got to the point where he would play, we would say to get a toy, and there was no more leaping for limbs.

Some long time later, we were to the point where I could hold his teeth for gentle tug of war, but he decided he didn’t like my skin in his mouth.

If he was really “One-Punch Man” he’d have wrapped it up in the first episode.

Just kidding! I’m also looking forward to it.

Plus side is actual strong techniques.

Downside is irresponsible teachers, dangerous teaching practices and literal body dismorphia.
