The Instant Consequence Method

The moment teeth touch skin, all interaction stops. Freeze your hand so it does not turn into a chase target, then calmly stand up and turn your back. No eye contact, no words, no drama. Wait five seconds, then re-engage. If teeth touch again, repeat.

Consistency is everything. If one family member allows mouthing while another punishes it, your dog receives conflicting signals and defaults to the behavior that sometimes works. Everyone in the household must follow the same rule: teeth on skin means the fun immediately ends.
