How to Stop Puppy Biting: NZ Step-by-Step Guide

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

1. 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". 2. 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. 3. Reward calm. When the puppy chooses to lick or settle instead of bite, praise and treat — you're rewarding the behaviour you want. 4. 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. 5. 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.
