Key points:
- Puppy biting is a normal part of development and often becomes more noticeable during teething.
- Puppies may bite or mouth during play, exploration, teething, overstimulation or to get attention.
- Consistent training and positive reinforcement can help teach your puppy appropriate biting boundaries.
- Redirecting biting towards suitable chew toys gives your puppy a safer outlet for their natural urge to chew.
- Avoid physical punishment, yelling or rough hand play, as these reactions can make biting behaviours worse.
- If biting becomes increasingly intense or doesn’t improve with consistent training, a qualified trainer or vet can provide additional support.
Sharp little teeth, a mouth that won't quit, and fingers that have seen better days… sound familiar? If you're living with a new puppy, you know that puppy nipping can sometimes feel like a daily battle.
The good news is that puppy biting is completely normal, and with a bit of consistency, most puppies grow out of it well before adulthood.
If you’re wondering when puppies stop biting, you definitely wouldn’t be the first. The puppy biting phase should start to ease around six months old as teething becomes less uncomfortable.
Keep in mind that some puppies may take a little longer to stop teething or may need help to overcome biting habits.
Keep reading to learn why puppies bite, how to manage the behaviour with positive training, and when it might be time to seek extra help.
Why do puppies bite?
Puppy biting, often called puppy mouthing, is a completely normal part of how puppies explore the world and interact with their littermates and environment. A few common reasons include:
- Teething: Puppies lose their baby teeth between roughly three and six months old, and biting is often a way to relieve discomfort. It’s similar to what babies do when they’re teething.
- Exploration: Puppies use their mouths to investigate textures and objects, much like human babies use their hands.
- Play: Biting can be a normal part of puppy play, especially with other dogs.
- Overstimulation: An overtired or overexcited puppy will often nip more than usual.
- Attention seeking: Biting can become a learned way to get a reaction, even a negative one.
Understanding why your puppy is biting makes it much easier to respond in a way that helps, without becoming annoyed or frustrated.
Normal puppy mouthing vs problem biting
Most puppy biting is mouthing rather than aggression. Soft, exploratory nips during play are a normal stage of development, and bite inhibition – learning how to control the pressure of their jaw – is something puppies are still actively developing. That’s why they can sometimes take it too far; it’s part of learning boundaries and control.
Keep an eye out for a puppy that bites excessively hard, repeatedly draws blood, or bites while displaying growling, stiff body language or guarding behaviour. These signs may need specialist intervention from a vet or qualified trainer, especially if they continue beyond the usual teething window.
Keep a simple note of when your puppy’s biting is at its worst. Spotting patterns around meals, visitors, playtime or certain times of day can help you anticipate nipping and manage it before it starts.
How to stop puppy biting: tips that work
There are a few ways to stop puppy biting that work best when used consistently, ideally from the day your puppy comes home. Positive reinforcement puppy training is a foundational step in your puppy’s development.
It’s important to reward behaviours you want to see more of, rather than only correcting those you don't.
If you're wondering how to train a puppy not to bite, try these tips:
- Redirect to a toy. The moment your puppy starts mouthing your hands or clothing, swap in an appropriate chew toy.
- Use a yelp and withdraw. A brief "ow" followed by temporarily stopping play can help teach your puppy that biting too hard ends the interaction.
- Stay consistent. Make sure everyone in the household responds to biting the same way so your puppy isn't getting mixed messages.
- Reward gentle behaviour. Praise and treats for calm play or gentle mouthing reinforce the behaviour you want to see more of.
- Manage overstimulation. If your puppy tends to nip more when overtired, build in regular rest breaks.
- Keep training sessions short. Little and often works better than long sessions, especially for young puppies with short attention spans.
- Get them moving. Regular exercise and mental stimulation can help reduce excess energy that may contribute to nipping.
Most puppies respond well to a combination of these puppy training tips within a few weeks. Remember to be patient, as every dog is different and progress can depend on their age, breed and temperament.
Toys to help with puppy biting
Giving your puppy plenty of appropriate things to chew is one of the most effective ways to manage puppy biting. A good chew toy satisfies the urge to mouth and bite while protecting your hands, furniture and favourite shoes in the process.
Look for soft, teething-friendly options for very young puppies and more durable chews as their adult teeth come through.
Shop the range of dog chew toys at Petstock, including teething-friendly silicone options, interactive tug and fetch toys, and longer-lasting chews to redirect those sharp little teeth towards something less “ouch-worthy”.
What not to do when your puppy bites
Here are a few things to avoid when your puppy starts to nip or bite:
- Avoid rough hand play. Wrestling with bare hands can teach your puppy that biting hands is a fun game.
- Never physically punish your puppy. This can increase fear and anxiety and may worsen biting over time.
- Don't pull away abruptly. Quick movements can encourage your puppy to chase and nip.
- Avoid yelling. A loud reaction can overstimulate an excited puppy rather than calm them down.
When to seek extra help
If your puppy's biting isn't improving after a few weeks of consistent training, or if it's becoming more intense over time, consider getting some extra support.
Puppy obedience training classes are a great option for addressing puppy behaviour training needs early. A qualified trainer can identify what's driving the biting and tailor a plan to stop puppy nipping in your specific situation.
Petstock also offers a puppy school program, which is a great way to socialise your puppy with other dogs while building the bond and trust between puppy and owner.
