While there are a variety of techniques to teach bite inhibition, one strategy is to emit an audible high pitched "Ouch!" when your puppy mouths you too hard, then completely withdraw your attention for a few seconds. Then reengage your puppy in play with an appropriate toy.
This must be done every time your puppy bites too hard. This training teaches your puppy that he or she is not allowed to put pressure on people or clothing. However, your pet still needs to chew, so you will need to provide proper chew toys to exercise the jaws.
If your puppy continues to bite despite your efforts, consider increasing his or her level of exercise and adding more opportunities for mental stimulation with puzzle toys, safe chews, and playdates. If you are concerned that the biting is not play, reach out to your veterinarian for help or a referral to a veterinary behaviorist.
