Those needle-sharp puppy teeth take everyone by surprise. If you are wondering how to stop a puppy biting, the first thing to know is that it is completely normal, and the second is that you can absolutely teach a gentler mouth without ever telling your puppy off. Puppies explore the whole world with their mouths, and mouthing and play-biting are how they learn about the things (and hands) around them. The goal is not to punish it, but to redirect it, so your puppy learns what is fine to bite and what is not.
I meet a lot of puppies in the salon, and the confident, happy ones are almost always the ones whose owners have gently guided this rather than scolded it. So let me walk you through the calm, kind way.
Why puppies bite and mouth
Understanding the why makes the fix much easier. Puppies mouth and nip because:
- They are playing. Chasing, wrestling and mouthing is how puppies play with their littermates. Your hands and ankles are simply the nearest playmates.
- They are teething. Sore, itchy gums make everything feel better to chew. This phase typically lasts until around six or seven months old.
- They are overtired or overexcited. A puppy who has tipped into the "zoomies" often gets nippier, much like an overtired toddler.
- They are exploring. Mouths are how puppies investigate texture, taste and everything new.
The Dogs Trust guide to puppy mouthing and biting makes the reassuring point that this looks and feels dramatic but is normal, and most puppies grow out of it with a little gentle guidance.
The golden rule: redirect, do not punish
Every time those teeth land on skin, the plan is the same: calmly redirect onto something they are allowed to bite. Keep a soft toy or a rope toy within reach so you can offer it the moment play gets mouthy. You are teaching a simple lesson: teeth on toys, never on people.
Learn to read the wind-up too. A burst of energy, bouncing, pouncing and batting with the paws usually comes just before the biting starts. Get the toy in first and you head the whole thing off, which is far easier than reacting after the fact.
What to do the moment teeth touch skin
When your puppy does catch you, this gentle sequence works beautifully:
- Stay calm and still. Do not snatch your hand away fast, as a moving hand looks like a brilliant game.
- Pause the fun. Calmly stop playing, go quiet and still for a moment. If needed, stand up and step away for a few seconds.
- Redirect. Offer a toy and happily carry on the game once teeth are on the toy, not on you.
- Reward the good. Praise gentle mouths and calm play so your puppy learns which choices keep the fun going.
This teaches your puppy that biting skin ends the game, while gentle play keeps it going. It is the same "bite inhibition" they would learn from their littermates, just guided by you.
Groomer's tip: Never use your hands as toys, however cute it is when they are tiny. A puppy who learns that hands are for wrestling grows into a bigger dog who still thinks so. Use a toy every single time and your future self (and your groomer) will thank you.
Help a teething puppy
If teething is driving the biting, give those sore gums something legitimate to work on:
- Puppy-safe chew toys, ideally a variety of textures (rubber, rope, soft).
- A damp flannel popped in the freezer for a soothing cold chew (supervise, and take it away once soggy).
- Frozen puppy-safe treats or a filled Kong.
- Rotate the toys every day or two, because a "new" old toy keeps them far more interested.
Set your puppy up to succeed
A lot of biting is really an overtired, under-stimulated puppy asking for help. Make sure they are getting:
- Enough rest. Puppies need a huge amount of sleep. Overtired puppies bite more, so quiet nap times behind a stair gate can work wonders.
- The right kind of play. Short, calm games and gentle brain work tire a puppy out better than endless chasing, which just winds them up.
- Consistency from everyone. The whole household needs to follow the same "teeth on toys" rule, or your puppy gets mixed messages.
The Dogs Trust guide to common puppy problems has more on building these good habits early.
When to seek a little extra help
Play-biting should ease over the coming weeks and months as your puppy matures and learns. If the biting seems genuinely aggressive rather than playful (stiff body, growling, hard bites that are not part of a game), or it is simply not improving with consistent, kind redirection, it is worth getting tailored advice. A good starting point is a qualified, reward-based trainer or behaviourist accredited through the ABTC or APBC, or a chat with your vet if you are at all worried.
Frequently asked questions
At what age do puppies stop biting?
Most puppies grow out of the worst of the mouthing and nipping by around six or seven months, once teething is over and they have learned better manners. Consistent, gentle redirection speeds it along.
Should I say "ouch" or yelp when my puppy bites?
A brief, calm pause in play works better than a dramatic yelp. For some puppies a high-pitched noise actually winds them up further, so if that happens, simply go still and quiet and end the game instead.
Is it normal for a puppy to bite a lot?
Yes, it is very normal, especially during teething and in bursts of excited play. It can feel relentless, but it is a phase. Redirecting onto toys and making sure your puppy is well rested makes a big difference.
How do I stop my puppy biting my children?
Keep interactions calm and supervised, teach children to stay still (not run and squeal, which triggers chasing), and always have toys handy to redirect. Give the puppy plenty of quiet rest away from the children too.
