How to stop puppy biting and nipping
If your puppy treats your hands like chew toys, you're not alone — and your puppy isn't "aggressive". Mouthing is how puppies explore the world, play and relieve teething discomfort. The goal is to teach them what's OK to bite and how gentle to be.
What's normal, by age
| Age | What to expect |
|---|---|
| 8–12 weeks | Lots of mouthing during play. Sharp baby teeth. Short attention span. |
| 3–6 months | Teething. Biting and chewing often peaks, especially when tired or over-excited. |
| 6–8 months | Adult teeth are in. Mouthing should be clearly decreasing with consistent training. |
The gentle plan
- Always have a toy ready. Keep tug toys and chews within reach in every room. When your puppy goes for your hands, redirect their mouth onto the toy and make the toy fun by moving it.
- Pause play when teeth touch skin. Say "oops" calmly, stop moving and take your hands away for a few seconds. Then offer a toy and resume. Your puppy learns: biting people ends the fun; biting toys keeps it going.
- Stay still. Pulling your hands away quickly or flapping makes you look like a toy. Slow, boring hands are less exciting to bite.
- Reward calm behavior. When your puppy lies down calmly or licks instead of biting, quietly praise and give a treat. Catch the good moments.
- Watch for the "overtired zoomies". Like toddlers, puppies get bitey when they're tired. Most young puppies need 16–20 hours of sleep a day. If biting suddenly gets worse, it's often nap time — offer a chew in a quiet crate or pen.
Teething relief
Offer safe chews sized for your puppy, and toys that can be chilled in the fridge. Rotate toys every few days to keep them interesting. Ask your vet which chews are appropriate for your puppy's age and size.
What not to do
- Don't hit, tap the nose, hold the mouth shut or "scruff". These can scare your puppy, damage your relationship and even increase biting.
- Don't play rough games with hands. Wrestling with your hands teaches that hands are toys.
- Don't expect it to stop overnight. Consistent responses from everyone in the home make the difference.
Children and puppies
Supervise all interactions between puppies and young children. Teach children to stand still "like a tree" and fold their arms if the puppy gets mouthy, and to call an adult. Give the puppy a safe space where children don't disturb them.
When to get help
Talk to your vet or a qualified behavior professional if biting is getting harder and more frequent after 5–6 months, if it comes with growling or stiff body language outside of play, or if your puppy guards food or toys intensely.
