You sit down on the floor to cuddle your new puppy, and within seconds there are needle-sharp teeth on your fingers, your sleeve and your shoelaces. The kids have started keeping their feet up on the couch. You know it is normal, but it still hurts.
Puppy biting is one of the most common things new owners ask us about, and it is a stage you can shape. Puppies explore the world with their mouths, and they need to learn, gently and consistently, that human skin is not a chew toy. This guide covers redirecting, pausing play, calm petting, rest, children, chewing and teething.
Why Puppies Bite and Nip
Mouthing is how puppies play, explore and soothe themselves. Most nipping comes from play (hands and moving clothes look like great toys), teething, excitement, boredom or, very often, simple tiredness.
Give That Busy Mouth Better Options
Short training games, sniffing time outdoors, food puzzles and a food toy stuffed with part of their meal all use up energy in a healthy way. Fetch and tug with a toy are great too. Skip rough games with hands, like wrestling or pretend boxing, because they teach your puppy that hands are for biting.
When your puppy starts mouthing you, offer a toy instead. Keep toys within reach in every room, and have a second one ready, because puppies often drop the first within seconds. A long, floppy tug toy keeps teeth further from your fingers.
Pet and cuddle your puppy mostly when they are calm, sleepy or busy chewing. Those are the moments they are least likely to nip, so you get to reward the gentle behavior you want.
Pause the Fun When Teeth Touch Skin
When your puppy's teeth land on skin or clothes:
- Say "Oops". This is a no reward marker: a calm, neutral word that tells your puppy that choice did not earn the reward, so the game pauses.
- Go still. Fold your arms, stand up or turn away for a few seconds.
- Restart gently. When your puppy is calm, start playing again, ideally with a toy.
- Leave if it keeps happening. If your puppy comes straight back for your hands, step over a baby gate or out of the room for about 30 seconds, then come back calmly and try again.
Teeth on people make the fun stop, and gentle play keeps it going. Avoid yelling, flapping or snatching your hands away, as these make the game more exciting.
Never use physical punishment for biting, such as tapping the nose, holding the mouth shut or pinning your puppy down. It can frighten your puppy and teach them to worry about hands.
Teach a Calm Response to Petting
For puppies who nip the moment a hand comes near, two short exercises help.
A quick consent check. Pet your puppy gently for a few seconds, then stop and take your hand away. If they lean in, nudge your hand or look up at you, they are asking for more, so pet again briefly. If they move away, mouth your hand or get wriggly, give them a break. Petting stays calm, and your puppy gets a say.
Petting with a treat hand. This uses a marker: a word like "Yes" that tells your puppy the exact moment they got it right, followed by a reward.
- Hold a few small treats in one hand and pet your puppy once with the other.
- Before they can turn to nip, bring the treat hand to their nose.
- As their head turns toward it, say "Yes" and give a treat.
- Slowly build up to two or three strokes before the treat appears.
Rest Matters More Than You Think
Young puppies need far more sleep than most people expect. An overtired puppy is like an overtired toddler: wild, bitey and unable to settle. Evening biting is very often tiredness. After play and a potty trip, settle your puppy in their crate or pen with a safe chew. Our guide to crate training shows how to make it a place they like.
Kids and Puppies
Children and puppies can be great friends, with an adult running the show.
- Supervise every interaction, and use a gate or pen when you cannot watch.
- Teach children to stand still, fold their arms and look away if the puppy nips, then call an adult. Running and squealing turns it into a chase game.
- Give children a long tug toy, so teeth go on the toy rather than on hands.
- End play before things get wild, then give the puppy a nap.
Mouthy puppies often jump up too, so our guide to stopping your puppy jumping on people is a good next read.
Inappropriate Chewing and Puppy-Proofing
Chewing is a need, not a bad habit, so the aim is to steer it.
- Puppy-proof. Pick up shoes, socks, kids' toys and cables, and block off rooms you cannot puppy-proof.
- Supervise or confine. When you cannot watch, use a crate, a pen or a gated area with safe toys.
- Notice good choices. When your puppy chews their own toy, praise them quietly.
- Swap, don't chase. If they grab something they shouldn't have, trade it for a toy or a treat. Our guide to teaching "Drop it" helps here.
Teething
Most puppies grow their adult teeth between around 3 and 7 months of age, and sore gums mean more chewing. Soft rubber teething toys, or a wet rope toy chilled in the freezer and given under supervision, can help. Check with your vet if your puppy seems in real pain or goes off their food.
Frequently Asked Questions
When do puppies stop biting?
Many puppies mouth much less once teething is over, especially when the family has been consistent. Mouthy play can return in adolescence, between about 6 and 18 months, so keep practicing. Our guide to the teenage dog phase explains why.
Is my puppy being aggressive?
Nearly all puppy biting is play. If your puppy growls or snaps over food, toys or handling, or the biting seems driven by fear, talk to your vet and a trainer early.
How Dogwise Can Help
Chewing and everyday puppy manners are core parts of our Puppy Foundations program for puppies of around 16 weeks to 6 months. Your puppy lives in their trainer's home, not a kennel, and practices gentle play, settling and good chewing choices in everyday life. Then your trainer shows you how to keep it going in your own home, with follow-up sessions and lifetime support after that. For large or fast-growing puppies, Big Puppy is often the better fit.
