A lot of owners panic when their puppy starts biting.
If you’ve never owned a puppy before, you may genuinely think you accidentally picked the only puppy in the litter possessed by demons… or a tiny fluffy psychopath. 😅
But let me reassure you: puppy biting and mouthing is completely normal puppy development.
If your puppy is also zooming around the house, struggling to settle, eating everything they find, or generally acting like they’ve had six espressos before bed, you may also find this helpful: Is This Normal Puppy Behaviour?
That doesn’t mean we ignore it, allow puppies to bite human skin, or just “wait it out”. But it does mean we need to stop only asking:
“How do I stop it?”
…and start asking:
“Why is my puppy doing it?”
Because once you understand why puppies bite, mouth, grab sleeves, attack shoelaces, or turn into tiny furry crocodiles at 7pm, things suddenly start making a lot more sense.
Puppy Biting Quick Summary
- Puppy biting and mouthing is usually normal puppy development.
- Evening puppy biting is often linked to overtiredness and over-arousal.
- Teething, frustration, hunger, stress, and overhandling can all make biting worse.
- Chewing, licking, sniffing, sleep, and calm enrichment can help puppies regulate.
- Avoid yelping, shouting, pinning puppies down, or holding their mouth shut.
- The goal is not punishment. The goal is understanding why your puppy is struggling.
Understanding Puppy Biting and Mouthing
Puppy biting can feel personal, especially when your hands, sleeves, ankles, dressing gown cord, and last remaining bit of patience are all under attack.
But most puppies are not trying to upset you. They are learning how to use their mouth, how to cope with excitement, how to manage frustration, and how to regulate themselves in a very busy human world.
This is why puppy biting advice needs to be more thoughtful than simply saying “stop it”. If we only focus on stopping the behaviour in the moment, we can miss the reason the puppy is doing it in the first place.
Most Puppy Biting Is Not Aggression
This is probably the biggest reassurance I can give new puppy owners.
Most puppy biting is not dominance, aggression, spite, revenge, or your puppy trying to “be the boss”.
A lot of owners quietly worry they have an aggressive puppy, especially when the biting feels hard, frantic, or relentless. In reality, many puppies are simply overwhelmed babies still learning how to regulate themselves.
Puppies explore the world with their mouths. They are teething, learning, overexcited, frustrated, overtired, curious, impulsive, and still developing emotionally.
Think overtired toddler energy… but faster and with sharper teeth.
If your puppy gets particularly mouthy in the evenings, zooms around the house, bites clothes, grabs ankles, or suddenly loses all ability to make sensible life decisions, this is incredibly common.
Evening puppy biting can be especially intense because your puppy may have been taking in new sights, sounds, smells, visitors, handling, play, and excitement throughout the day. By the evening, their little brain may simply have run out of sensible choices.
A lot of puppies actually bite more when they are:
- Overtired
- Over-aroused
- Frustrated
- Overstimulated
- Teething
- Hungry
- In need of rest
This is why appropriate sleep, calm enrichment, chewing, licking, sniffing, and lowering arousal levels can make such a huge difference.
If your puppy biting gets worse at night or during the evening “witching hour”, it may be worth looking at the whole day, not just the moment the teeth appear.

What Actually Helps Puppy Biting?
One of the biggest mistakes owners make is trying to battle through puppy biting with nothing prepared.
Have your “defence weapons” ready before the tiny land shark activates.
- Appropriate chews
- Stuffed Toppls
- LickiMats
- Scatter feeding
- Snuffle mats
- Frozen enrichment
- Tug toys
Chewing, licking, and sniffing can help puppies regulate emotionally and lower arousal levels.

What NOT To Do When Your Puppy Bites
Unfortunately, even in 2026, there is still a huge amount of outdated puppy advice online.
I still regularly see people recommending things like:
- Yelping like another puppy
- Holding the puppy’s mouth shut
- Pinning puppies down
- Alpha rolling
- Shouting “NO!” loudly
- Smacking noses
- Wrestling puppies
My grandad used to tell me to “yelp like their mum”.
But… we are not dogs.
Your puppy knows full well you are a human and is probably wondering why Karen has suddenly started squeaking at them.
For a lot of puppies, squealing, waving hands around, pushing them away, or running off can actually increase arousal levels and make the game MORE exciting.
Some puppies will become more frustrated. Some may become more excited. Some may become fearful.
And fearful puppies can absolutely come back harder.
Pinning puppies down or physically forcing them into restraint is especially concerning because it can damage trust, create fear, increase stress, and remove the puppy’s ability to move away appropriately.

Why Punishment Can Make Puppy Biting Worse
Punishment can look like a quick fix because it may interrupt the behaviour in the moment. But interruption is not the same as understanding.
If a puppy is biting because they are overtired, scared, over-aroused, frustrated, teething, hungry, or overwhelmed, punishment does not meet the need underneath the behaviour.
It can also teach the puppy that human hands are unpredictable or scary, which is the opposite of what we want when we are trying to build trust.
Instead of thinking, “How do I stop this right now?”, try thinking, “What is my puppy telling me?”
That one question changes everything.
Overhandling, Children & Puppy Mouthing
Another really common cause of puppy biting is overhandling and restraint.
Especially with children.
A lot of puppies mouth because they are overwhelmed, frustrated, tired, or simply do not want to be picked up and cuddled anymore.
This does not make them “bad”.
It means they are communicating.
Teaching children how to interact calmly and appropriately with puppies is incredibly important.

Never Allow Teeth On Human Skin
Although puppy biting is normal, I personally do not allow puppies to rehearse mouthing human skin.
It may seem cute at 10 weeks old, but it becomes much less adorable when a larger adolescent dog is grabbing sleeves, hands, feet, or clothing.
The goal is not punishment.
The goal is calmly redirecting puppies onto appropriate outlets and preventing rehearsal where possible.

You Are Probably Expecting Too Much
I say this kindly, because social media has completely distorted people’s expectations of puppies.
People see perfect puppies calmly walking beside owners online and assume their own puppy should already:
- Sleep perfectly
- Settle calmly
- Never bite
- Ignore distractions
- Come back instantly
- Walk beautifully on lead
Meanwhile, real puppies are out here trying to eat leaves, attack trouser legs, and commit crimes against furniture.
If your puppy is struggling, you are not failing.
This stage is hard work. But it is also normal.
