How to Stop Puppy Biting: NZ Step-by-Step Guide
Puppy biting and mouthing is normal but stoppable. A calm, NZ-friendly step-by-step plan using bite inhibition, redirection and positive reinforcement.
The quick answer: puppy biting is completely normal — puppies explore the world with their mouths and are teething until around 6 months. The goal isn't to punish it but to teach bite inhibition (soft mouth) and redirect those needle teeth onto the right things. With calm, consistent practice over a few weeks, almost every puppy grows out of it.
Why puppies bite
- Teething — sore gums (peaks roughly 3–6 months) drive chewing.
- Play and exploration — mouthing is how puppies interact with littermates and the world.
- Overtiredness — an overtired puppy gets "bitey" much like an overtired toddler gets cranky.
- Attention — if biting gets a big reaction, it can become a game.
The step-by-step plan
- Yelp and pause. When teeth touch skin, give a short high "ouch", then stop play and stand up. This mimics how littermates teach "too hard".
- Redirect onto a toy. Always have a chew toy within reach; swap your hand for it the instant the puppy mouths you. Reward chewing the toy.
- Reward calm. When the puppy chooses to lick or settle instead of bite, praise and treat — you're rewarding the behaviour you want.
- Time-outs for over-arousal. If biting escalates, calmly step behind a gate or leave the room for 30–60 seconds. No drama. Return and try again.
- Meet the needs first. A well-exercised, mentally-stimulated, well-rested puppy bites far less. Build in nap time — overtired puppies are the bitiest.

What NOT to do
- Don't smack the muzzle, hold the mouth shut, or shout. It teaches fear, not soft mouth, and can make a dog hand-shy. NZ welfare guidance (SPCA) and modern trainers all favour positive, force-free methods.
- Don't play rough hand-wrestling games that reward biting hands.
Teething help
Cold can soothe sore gums — a damp, frozen flannel or a chilled rubber chew toy works well through a Kiwi summer or any time gums are sore. Make sure chews are puppy-safe and the right size.
When to get help
If a puppy over ~6 months is still biting hard, the biting seems fearful or aggressive (stiff body, growling, guarding), or you're not seeing progress, book a force-free puppy class or a qualified NZ dog trainer/behaviourist early. Settling routines matter too — see our guide on settling a rescue dog in NZ for calm-home principles that also apply to puppies.
Quick takeaways
- Puppy biting is normal teething/play — teach soft mouth, don't punish.
- Yelp + pause, then redirect to a chew toy, and reward calm.
- Rest matters: overtired puppies bite most.
- No smacking or muzzle-grabbing — it backfires.
- Still biting hard past 6 months, or fearful biting → force-free trainer.
