Puppy biting is a normal part of growing up. It usually doesn’t mean you’ve brought home an aggressive dog. Puppies explore with their mouths, and RSPCA Victoria describes mouthing as a developmental behaviour of young pups (RSPCA Victoria). The trouble is those needle-sharp teeth, and whatever hands, ankles or children end up in the way.
A few practical options help many owners: keep hands out of games and offer something appropriate to chew, pause play when teeth keep landing on skin, and make sure your puppy gets proper rest. Every puppy is different, and a mouthy puppy usually needs teaching rather than fixing, plus a household that agrees on the plan.
Key Takeaways
– Mouthing is a normal part of puppy development and is different from biting linked to aggression.
– Options include keeping hands out of play, offering a chew and pausing play when teeth land.
– Chew items, short sessions and real rest help a puppy settle.
– Supervise children with the puppy, and see your vet if biting could be linked to pain.
Why do puppies mouth and bite so much?
Puppies mouth because it’s how they explore and play. RSPCA Victoria puts it simply: “Just as children like to explore the world by putting things in their mouths, so too do puppies.” It adds that nipping, mouthing and biting is a form of puppy social interaction that is rarely done with malice or aggression (RSPCA Victoria).
Mouthing is also how puppies learn how hard is too hard. According to RSPCA Victoria, pups usually learn the strength of their bite during the first few weeks of life with their siblings, and too little chance to practise can leave older dogs lacking bite inhibition. Once your puppy comes home, some of that learning carries on with you.
It feels full-on because a puppy has lots of energy and not much self-control yet, and a waving hand or a squealing child looks a lot like an invitation to play. None of that makes your puppy “bad”. They just haven’t learned the house rules.
Canine Services International is a dog training and dog behaviour business in Boronia, Melbourne’s east, led by Brad Griggs, canine behaviour specialist. Alongside dogs other trainers and vets couldn’t help, CSI works with everyday puppies and pet dogs, through an indoor facility, one-on-one sessions, small groups and online. No magic equipment, no overnight fix.
When is it mouthing, and when is it biting to worry about?
Most mouthing is part of play. Biting is the one to watch. RSPCA Victoria makes the distinction directly: “Mouthing is different to biting, which is usually referred to in the context of aggression and is something to be more worried about” (RSPCA Victoria). The body language around the teeth usually tells you which one you’re seeing.
| Play mouthing often looks like | Worth a closer look |
|---|---|
| A loose, wiggly body, bouncing or play bows | A stiff or frozen body just before the bite |
| Mouthing during excitement, zoomies or when you move | Growling with a hard stare, or lips pulled back |
| A puppy who happily switches to a toy you offer | Biting when someone goes near food, toys or a resting spot |
| Nipping that comes and goes with the game | Biting when touched or picked up, especially in one spot |
Puppy teeth are sharp, and RSPCA Victoria notes that nips from puppy teeth can hurt, so even a playful nip can break the skin. Clean any wound, and see a doctor if a child is hurt or the wound looks deep. If bites are hard or frequent, talk to your vet or a trainer.
What should you do the moment your puppy bites?
Stay calm and keep it simple. Owners handle the moment in different ways, and no single script suits every puppy. The options below are widely used and easy to try at home. Whatever you choose, agree on it as a household, so your puppy gets the same message from everyone.
Keep hands out of the game
Hands that wave, tickle or wrestle make easy targets. Many owners find it helps to keep hands out of play and offer something the puppy is allowed to chew instead, such as a long toy or a chew. Keep a toy within reach in the rooms you use most. Ask your vet which chews suit your puppy’s age and size, since chews vary a lot in hardness and shape.
Pause play when the teeth keep landing
If the nipping keeps coming back, a short pause in play is another option. Keep it low-key, so the break feels like a quiet moment rather than a new game. With young children around, a playpen or baby gate can make a pause easier to manage.
Check whether your puppy needs a rest
Overtired puppies often get mouthier. If the biting ramps up late in the day or after a busy outing, a quiet rest space with something to chew may settle things better than more play.
Get advice that fits your puppy
Every puppy is different, so what suits one household may not suit another. A trainer can help you tailor an approach to your puppy’s age, energy and home.
What daily routine helps a mouthy puppy?
Chew time, short bursts of play and training, and plenty of rest. RSPCA Victoria notes that “Puppies, like children, need constant entertainment”, and suggests enrichment to keep them mentally and physically stimulated so they’re less likely to mouth at you or your clothing (RSPCA Victoria).
Time with other dogs
Other dogs can teach a puppy a lot about bite strength. RSPCA Victoria encourages owners to provide plenty of opportunities for their puppy to interact with other puppies and friendly, vaccinated adult dogs, and to consider a good puppy class with supervised play. Talk to your vet about vaccination timing first. If you’re weighing up structured options, you can see CSI’s current classes and programs.
Chew items and enrichment
Give your puppy things they’re allowed to chew before they go looking for your fingers: treat-dispensing toys, puzzle feeders and chew items. RSPCA Australia suggests rotating toys daily so your puppy doesn’t get bored with them (RSPCA Australia).
Rest and settling
An overtired puppy is often a mouthier puppy, so plan naps into the day. RSPCA Australia suggests setting your puppy up in a safe space with a delicious treat, something to chew and an enrichment toy like a puzzle feeder, and describes a crate as an ideal secure place for a puppy to sleep. If you’re starting with a crate, crate training a puppy covers the early days.
Short sessions, starting now
Gentle training and socialisation can start soon after your puppy comes home. RSPCA Australia describes a “critical socialisation period” for puppies between approximately 2.5 and 14 weeks of age, and says experiences during this time can shape their behaviour for the rest of their lives (RSPCA Australia).
It also advises keeping socialisation sessions short and positive, introducing one to two new things at a time so your puppy isn’t overwhelmed. Simple skills like sit, come and leave it fit neatly between naps.
A sample day might look like this:
- Wake up, toilet break, then a short play session with a long toy.
- A chew or puzzle feeder, followed by a nap in a safe space.
- A short training session on sit, come or leave it.
- A socialisation outing. RSPCA Australia suggests carrying a puppy that isn’t fully vaccinated so they can safely learn about the world, and keeping walks for once they’ve had all their routine puppy vaccinations (at least 14 days after the last one). Check timing with your vet.
- A calm evening chew, then bed.
How do you keep children and a mouthy puppy safe together?
Have an adult actively supervising whenever children and the puppy are together, and give both of them simple rules. Puppies and young kids wind each other up fast, and a gentle game can tip into nipping and squealing within moments. Clear rules protect the children and stop the puppy practising rough play.
Rules worth trying at home:
- Children offer a long toy, not hands or feet.
- Play sitting down or standing calmly, and skip chasing and wrestling games.
- If the puppy gets too mouthy, children stand still, fold their arms and look away while an adult steps in and pauses the play.
- The puppy’s bed or crate is a no-go zone for children, so the puppy has somewhere to rest.
- Adults handle feeding and taking things off the puppy.
- Use baby gates or a playpen when you can’t watch closely.
If your child is now scared of the puppy, that’s understandable after a few painful nips. Give them a safe job, like tossing a toy from the couch, and let their confidence come back slowly.
When should you get professional help with puppy biting?
Get help if the biting looks like more than play, is getting worse rather than easing, or is linked to guarding, handling or fear. RSPCA Victoria acknowledges that “Sometimes you need a bit of extra support” and suggests considering a behaviourist (RSPCA Victoria). Signs worth acting on include:
- Stiffening, freezing, growling or a hard stare before a bite.
- Biting around food, toys, chews or a resting spot.
- Biting when the puppy is touched, picked up, groomed or examined.
- Bites that are getting harder or more frequent as the weeks go on.
- A puppy that can’t settle, even with rest and enrichment in place.
- Children in the home who are frightened of the puppy, or have been hurt.
Start with your vet if the biting appeared suddenly, if your puppy reacts when touched in one area, or if anything seems off with their health. Pain can show up as behaviour, so rule it out first. Any decision about medication is your vet’s to make.
Once health has been checked, a behaviour professional can help you work out what’s driving the biting. Canine Services International in Boronia puts it this way: “Most problems are not solved by suppressing them. We build the dog underneath, so it can feel and act differently.” Brad Griggs works with everyday puppies and pet dogs too, and you can browse all services to see the options.

Frequently Asked Questions
When should a puppy start training?
Gentle training and socialisation can start soon after your puppy comes home. The RSPCA describes a critical socialisation period between approximately 2.5 and 14 weeks of age, when experiences can shape behaviour for the rest of a dog’s life. Keep sessions short and positive, introduce one or two new things at a time, and talk to your vet about vaccinations before outings and group play.
Is it normal for puppy bites to draw blood?
Puppy teeth are sharp, and the RSPCA notes that nips from puppy teeth can hurt, so a nip can break the skin. Clean any wound, and see a doctor if a child is hurt or the wound looks deep. Watch the context too: stiffening, growling or guarding is more concerning. If bites are hard or frequent, talk to your vet or a trainer.
How do I stop my puppy biting my kids?
Have an adult supervise closely, give children a long toy to offer instead of their hands, and skip chasing games. If the puppy gets too mouthy, children can stand still and fold their arms while an adult steps in and pauses the play. Give the puppy a rest space that children leave alone, and ask a trainer what suits your household.
Will playing with other dogs help my puppy’s biting?
It can help. The RSPCA explains that pups usually learn the strength of their bite in the first few weeks of life with their siblings, and encourages time with other puppies and friendly, vaccinated adult dogs. A good puppy class offers supervised play with other puppies. Check with your vet about vaccinations before group play starts.
