Stopping puppy biting and mouthing

Updated 2026-10-16. General information, not veterinary advice.

Ask your vet or a qualified trainer. This guide is general information, not veterinary advice. If your puppy bites hard, growls when handled or guards food or toys, or if children are at risk, ask your vet and a qualified trainer or behaviourist for hands-on help.

Puppy teeth are sharp, and puppies use them for everything. Mouthing is normal, and so is the frustration of sore forearms. The goal is to teach your puppy that gentle mouths keep the fun going and that toys, not skin, are for chewing.

Why puppies bite

Exploration. Mouths are how puppies investigate.
Play. Puppies wrestle and mouth each other. They try the same with people.
Teething. Chewing can relieve sore gums as adult teeth come in.
Overtiredness. Overtired puppies often turn into little crocodiles. Many puppies need a lot of sleep.
Excitement or attention seeking. If biting gets a big reaction, it may continue.

What to avoid

Shouting, smacking, nose tapping, holding the muzzle or pinning your puppy down can scare them and teach them to be wary of hands. Wrestling with rough games can also encourage biting. We recommend a reward-based approach.

Teaching a softer mouth

Puppies learn bite inhibition, meaning how hard is too hard, from play with litter mates. You can continue that teaching.

Reward gentle play. When your puppy is calm and mouths softly or licks, praise and reward.
Pause when it hurts. If teeth hit skin, say “ouch” calmly, stop playing and move away for a short moment, or put a toy between you. Resume once your puppy is calm. This teaches that biting ends the fun.
Redirect. Offer a chew toy or tug toy and encourage your puppy to bite that instead. Reward when they do.
Keep it consistent. Everyone in the house, including visitors and children, should respond the same way.
Do not chase or flap. Waving hands and running away often makes it a game. Stand still, calm and boring, then redirect.

If your puppy keeps latching onto clothes or ankles, a short break in a pen or behind a gate with a chew can help them settle. This is a time-out for rest, not a punishment, so keep it calm and short.

Meet the chewing need

Puppies need appropriate outlets. Offer a variety of safe items, rotate them and supervise.

Chew toys of suitable size and hardness. Ask your vet about what is safe for your puppy. Our chew toys listings are provided for convenience only, not as recommendations.
Frozen, puppy-safe treats may soothe gums on hot days. Ask your vet what is appropriate.
Food puzzles and stuffed toys, from enrichment and play.
Short training games, such as sit, hand targets and walks on lead.

Never give anything your puppy could swallow in pieces. If chewed material is swallowed, or your puppy seems unwell, call your vet.

Manage the environment

Use baby gates and a pen so your puppy cannot reach shoes, cables and furniture. See our first week guide for puppy-proofing.
Keep a toy in your pocket for emergencies.
Plan naps. A tired puppy bites more. A quiet crate or bed helps, and our crate training guide explains how.
Exercise suited to age. Ask your vet how much is right.

Children and visitors

Supervise all interactions between puppies and children. Teach children to stay calm, avoid squealing or running, and to stand still like a tree and let an adult redirect the puppy. Give your puppy a toy or treat, and never leave small children alone with a puppy.

Sit, then greet

Many puppies bite when greeting. Teach a simple sit for attention: wait until all four paws or the bottom are on the floor, then reward and pet. Practise at the door with visitors, using treats. Pair this with the skills in loose-lead walking and reliable recall as your puppy grows.

When it is not just play

Seek help promptly if you see:

Hard bites that break skin more than occasionally
Stiffening, growling or snapping around food, toys or touch
Biting that is getting worse rather than better
A puppy that seems anxious, in pain or unwell

A vet can check for pain or health issues, and a qualified trainer can watch your puppy and show you what to do. Our training directory lists trainers (listed, not endorsed), so check qualifications and methods.

Stay patient

Mouthing is a phase that improves with time, rest and consistent guidance. Celebrate the moments your puppy chooses a toy or a gentle mouth, and keep sessions short and positive. It may feel endless right now, but most owners see steady progress.

FAQs

Is puppy biting normal?

Yes. Puppies explore the world with their mouths, and they also mouth during play and teething. It needs guidance, not punishment.

Should I hold my puppy's mouth shut or tap their nose?

No. Physical corrections can frighten your puppy, damage trust and sometimes make biting worse. Redirect to something appropriate and reward gentle behaviour.

When will my puppy stop biting?

It varies. Most puppies improve gradually with consistent training, enough sleep and chew outlets. Ask your vet or a qualified trainer if it is not improving.

What if the biting is hard or aggressive?

Stop the interaction safely and ask your vet and a qualified trainer or behaviourist for help promptly, especially around children.
