My Puppy Won't Stop Biting Me – What Should I Do?

One minute you're enjoying a cuddle with your new puppy. The next, those tiny teeth are attached to your sleeve, your shoelaces - or quite possibly your hand.

If you're beginning to wonder whether you've somehow brought home the world's smallest crocodile, you're certainly not alone.

Biting and mouthing are very common puppy behaviours. Puppies explore the world with their mouths, play with their mouths and need appropriate things to chew. Excitement, tiredness and frustration can make the behaviour much more noticeable too. Dogs Trust describes mouthing and biting as normal puppy behaviour while emphasising that puppies still need to learn appropriate ways to interact with people. Dogs Trust

The good news is that puppy biting doesn't mean you've got a "bad" puppy.

But there are things you can start doing today to make life considerably easier.

Why does my puppy bite me so much?

There usually isn't one single reason.

Your puppy could be:

exploring;

initiating play;

overexcited;

frustrated;

tired;

looking for something to chew;

trying to get your attention.

And sometimes several of those things are happening at once.

One useful clue is when the biting happens.

Does your otherwise charming puppy transform into a shark every evening?

That may tell you more than the biting itself.

Young puppies need a great deal of rest, and overtired puppies don't necessarily look sleepy. Sometimes they become increasingly frantic, mouthy and difficult to settle.

Dogs Trust specifically notes that adequate sleep is just as important as exercise when dealing with puppy mouthing. Dogs Trust

What should I do when my puppy bites me?

1. Try not to turn your hands into the toy

Waving your hands around, pushing your puppy away repeatedly or starting an energetic wrestling match can accidentally make things more exciting.

Instead, become rather boring for a moment.

Pause the interaction.

If necessary, stand up and move away briefly.

The idea isn't to frighten or punish your puppy.

You're simply teaching:

Teeth on people = interaction pauses.

Dogs Trust recommends withdrawing attention calmly when mouthing continues and returning once the puppy has settled. Dogs Trust

2. Redirect onto something your puppy can bite

Keep suitable puppy toys within reach.

When you can see the energetic, bitey mood arriving, redirect your puppy onto:

an appropriate chew;

a tug toy;

a stuffed food toy;

a puppy-safe enrichment activity.

This is often easier than waiting until your puppy is hanging from the leg of your trousers.

You're not merely saying "don't bite."

You're teaching:

"Bite this instead."

3. Watch for the overtired puppy

This is one that catches many new puppy owners out.

You've played with them.

You've trained them.

You've entertained them.

And they're getting crazier rather than calmer.

Your instinct might be:

"They must need more exercise."

Sometimes they actually need considerably less stimulation and considerably more sleep.

Dogs Trust notes that puppies can suddenly appear extremely energetic when they are becoming tired - including the familiar evening "zoomies." Dogs Trust

Try creating a calmer period:

lower the excitement;

put noisy toys away;

offer something soothing to chew;

allow your puppy to settle somewhere comfortable.

You may discover that the terrifying evening piranha was simply exhausted.

What shouldn't I do?

Try to avoid methods designed to frighten, intimidate or physically punish your puppy.

Shouting, smacking, grabbing their muzzle or deliberately frightening them doesn't teach them what you would prefer them to do.

You want your puppy to learn that humans are predictable and safe.

Calm redirection and reward-based training build that relationship far more effectively.

Prevent the biting before it begins

This is where life gets easier.

Start noticing patterns.

Perhaps your puppy tends to bite:

at 7pm every evening.

Or:

immediately after visitors leave.

Or:

during particularly energetic games.

Once you've identified the pattern, intervene before the biting begins.

You might offer an appropriate chew at 6:50pm.

Or follow an exciting game with a calm sniffing activity.

Or schedule a nap earlier.

Prevention is generally easier than trying to calm a puppy who has already reached full shark mode.

Make sure everybody follows the same rules

Puppies learn through repetition.

If one person allows rough hand play, another squeals and runs away, and somebody else tells the puppy off, the lesson becomes very confusing.

Decide as a household:

What happens when teeth touch skin?

A simple approach might be:

Stop interacting.

Calmly disengage.

Redirect onto an appropriate toy.

Resume interaction when your puppy is calmer.

Reward the behaviour you want repeated.

Consistency matters much more than perfection.

Will my puppy grow out of biting?

For many puppies, mouthing reduces considerably as they mature and learn appropriate ways to interact.

But don't simply wait for it to disappear.

You're helping your puppy develop the habits they'll carry into adulthood.

And remember: progress isn't always linear.

You may have three wonderful days followed by an evening during which your puppy apparently forgets everything they've ever learned.

That's puppyhood.

When should I seek professional help?

Normal puppy mouthing and genuinely concerning biting aren't necessarily the same thing.

If the behaviour appears unusually intense, causes serious injuries, seems connected with significant fear or guarding, changes suddenly, or you're simply worried by what you're seeing, speak to your vet or a suitably qualified reward-based behaviour professional.

Pain can also affect behaviour, so sudden or unusual behavioural changes shouldn't automatically be treated as a training problem.

A Whisker & Wag thought

Those little teeth can make puppyhood surprisingly exhausting.

But your puppy isn't giving you a hard time - they're learning how to live in a completely new world.

Calm repetition now builds the dog you'll be sharing your home with for many years to come.

Puppy biting FAQs

Why does my puppy bite me more than everybody else?

It can be because you interact with them most, your movements are particularly exciting, or they've learned that mouthing you starts a game. Look at what happens immediately before and after the behaviour.

Why is my puppy worse in the evening?

Overstimulation and tiredness can contribute. Puppies sometimes become more frantic rather than obviously sleepy when overtired. Dogs Trust

Should I yelp when my puppy bites?

Some puppies may pause, while others become more excited by the sound. A calmer strategy of stopping interaction and briefly withdrawing attention is often easier to apply consistently.

Should children play with a puppy that is biting?

Interactions between young children and puppies should be closely supervised. If play becomes too excited or mouthy, calmly separate them and give the puppy an opportunity to settle.
