Those needle teeth are one of the shocks of puppy ownership. One minute you are cuddling a fluffy angel, the next you are bleeding slightly and wondering whether you bought a small shark. Take heart: this phase is nearly universal, it has a purpose, and with a clear plan it passes faster than most people expect.
Why puppies bite
| Reason | What it looks like | What helps |
|---|---|---|
| Exploring | Mouthing hands, clothes, furniture | Plenty of legal chew toys and supervision |
| Play | Bouncy, loose body, play bows, chasing | Redirect to a toy, pause when teeth touch skin |
| Teething | Chewing everything, red gums, sore mouth | Cold or textured chews (see teething timeline) |
| Overtired | Frantic biting and zoomies late in the day | Nap in a crate or pen. Puppies need a lot of sleep |
| Wanting attention | Nipping when you stop interacting | Reward calm, ignore nipping, give an alternative job |
| Fear or discomfort | Stiff body, growling, snapping when touched or cornered | Give space and get professional guidance |
Puppies also learn “bite inhibition”, how hard is too hard, from play with littermates. When one yelped and walked away, the game stopped. You are teaching the same lesson, just with human rules.
The step-by-step plan
- Have a toy in every room. The moment teeth touch skin or clothes, calmly offer a toy and praise when it is taken.
- Pause play when teeth land. Say “ouch” calmly or stay silent, then stop moving and take your hands out of reach. Wait a few seconds. If your puppy bites again, stand up and leave for a minute or two. Some puppies find a high-pitched yelp exciting, so use whichever approach calms yours.
- Reward soft mouths. Offer treats from a flat palm. When a puppy takes gently, praise and reward. Teach “gentle” and “take it” cues.
- Swap hands for toys during play. Use tug toys or a flirt pole so hands are never the target. Avoid wrestling or rough games with your hands.
- Prevent the overtired spiral. Young puppies often sleep 18 hours a day. If biting spikes in the evening, put your puppy down for a nap with a chew in a crate or pen. Our crate training guide shows how.
- Burn energy and brain power. Short walks, sniffing games, food puzzles and training sessions all help. Browse indoor activities for dogs for ideas.
- Be consistent. Every family member should follow the same rules, or the puppy will learn that biting works for some people.

| Frozen or chilled toys | Sore gums | Chill, do not freeze rock-hard; supervise |
| Rope or tug toys | Interactive play | Supervise and throw away frayed pieces |
| Stuffed food toys | Calming, crate time | Count the calories in your puppy’s daily food |

Rules for kids and visitors
- Teach children to stay calm, stand still and “be a tree” if the puppy gets mouthy. Running and squealing makes it worse.
- Give kids a toy to hold and wave away from their hands.
- Supervise all play and end it before things escalate.
- Ask guests not to rile the puppy up with rough hand games.
A rough timeline
| Age | What is normal |
|---|---|
| 8 to 12 weeks | Constant mouthing, sharp baby teeth, learning bite inhibition |
| 3 to 6 months | Teething, heavy chewing, mouthing may peak |
| 6 to 12 months | Adult teeth in; mouthiness fades with training but adolescent testing is common |
Timelines vary by breed. Retrievers and herding breeds often stay mouthy longer, because holding and carrying things is in their blood.
When to call a professional
- Biting that breaks skin repeatedly and does not improve with training.
- Growling, stiffening, lip curling or snapping when you handle food, toys or the body.
- Fear-based biting in a puppy that hides or flinches.
- Sudden changes in behaviour, which can signal pain. Check with your vet and see our dog body language guide.
A qualified positive-reinforcement trainer or veterinary behaviourist can create a plan for your puppy.

Puppy biting FAQ
When will my puppy stop biting?
Most puppies get much better by 5 to 6 months with consistent training, as their adult teeth settle in. Some breeds stay mouthy longer, but it should steadily improve.
Should I yelp when my puppy bites?
It works for some puppies, but others get more excited. If a yelp makes it worse, stay silent and withdraw attention instead.
Why does my puppy bite more in the evening?
Overtiredness. The “witching hour” is common. Offer a chew and a nap rather than more play.
Is it okay to let my puppy mouth my hands?
Gentle mouthing is natural, but teach early that teeth on skin ends the game. It is easier than fixing it later.
How do I stop my puppy biting my feet and clothes?
Freeze, stop moving and offer a toy. Keep a tug toy in your pocket and teach “leave it” with treats.
Is my puppy aggressive?
Normal puppy play is loose and bouncy. Stiff posture, hard stares or growling over objects is different, so call a professional.
