Puppy biting and mouthing are normal parts of development. Puppies explore the world with their mouths, and teething can make chewing especially intense between 3-6 months of age. The goal is not to stop mouthing completely, but to teach appropriate bite inhibition and redirection.
Why Puppies Bite
- Teething discomfort
- Play behavior
- Overstimulation or overtiredness
- Attention-seeking
- Normal exploration
Teaching Bite Inhibition
Bite inhibition means teaching your puppy to control the pressure of their mouth.
- If teeth touch skin, calmly say ‘ouch’ and pause play briefly
- Redirect immediately to an appropriate toy
- Resume play once calm
- Be consistent – everyone in the household should respond the same way
Managing Teething
- Provide durable chew toys designed for puppies
- Rotate toys to maintain interest
- Offer chilled (not frozen solid) rubber toys for gum relief
- Avoid hard objects that may damage developing teeth
Preventing Escalation
- End play if biting becomes too intense
- Do not run away when playing - this encourages chasing and nipping.
- Ensure adequate naps – overtired puppies bite more
- Avoid rough play that encourages grabbing hands or clothing
- Reward calm interactions frequently
What NOT to Do
- Do not yell, but a firm “No Bite” may help.
- Do not hold the mouth shut or use physical punishment,
- Do not use aversive techniques that create fear
- Punishment can increase fear and may contribute to defensive aggression later.
