If you’re living with a puppy, chances are you’ve asked yourself at least once, “Why is my adorable little puppy trying to eat my hands?”
Puppy biting is one of the most common concerns new owners face. I often get panicked emails from owners of around 12 week old puppies saying that their puppy is biting so much and worrying that it means they’re aggressive.
Those tiny teeth can be surprisingly sharp, and what starts as playful mouthing can quickly become painful. The good news? Puppy biting is completely normal, and with the right approach, it will pass.
Let’s look at why puppies bite, when it tends to peak, what you should avoid doing, and most importantly, what you can do instead.
Why Do Puppies Bite?
Puppies explore the world with their mouths. Just as babies use their hands to investigate, puppies use their teeth.
Biting, mouthing and nipping are all natural puppy behaviours and can happen for several reasons:
They’re Exploring
Everything is new and exciting. Your puppy learns about textures, objects and people through their mouth.
They’re Playing
Puppies naturally play with their littermates by chasing, wrestling and mouthing. When they come to live with us, they often continue these behaviours with human family members.
They’re Teething
Puppies begin losing their baby teeth and growing their adult teeth at around 3-6 months of age. Chewing and biting can help relieve discomfort in their gums.
They’re Overtired
One of the biggest causes of intense biting is fatigue. Much like an overtired toddler, puppies can become overstimulated and struggle to regulate themselves. Many owners notice the “witching hour” when their puppy suddenly seems unable to stop biting.
They’re Overexcited
Exciting games, visitors, walks or busy environments can all increase arousal levels, making biting more likely.
When Does Puppy Biting Peak?
Most puppies go through a particularly bitey phase between 3 and 6 months of age.
This often coincides with teething and increased exploration as they grow. Many owners find the behaviour is at its most challenging around 4-5 months old.
The encouraging news is that with consistent guidance and appropriate outlets, biting typically reduces significantly as puppies mature and learn better ways to interact.
What Not To Do
When puppy teeth are sinking into your hands for the tenth time that day, it’s understandable to feel frustrated. However, some common approaches can make the problem worse.
Don’t Punish Your Puppy
Shouting, smacking, pinning your puppy down or using physical corrections can damage trust and create fear.
Puppies are not being naughty or dominant. They’re behaving like puppies.
What’s more, this can seem like play to them and actually accidentally encourage the behaviour.
Don’t Hold Their Mouth Shut
Physically restraining a puppy’s mouth can be frightening and may increase stress around handling.
Don’t Encourage Rough Play With Hands
Wrestling with your puppy using your hands teaches them that human skin is an appropriate toy. Use tug toys instead.
Don’t Expect Too Much Too Soon
Learning impulse control takes time. Your puppy isn’t deliberately ignoring you; they’re still developing physically and emotionally.
What To Do Instead
Provide Plenty of Appropriate Chews
Teething puppies have a genuine need to chew. Chewing eases the pain of their new adult teeth growing in.
Offer a variety of safe chews, puppy toys, stuffed food toys and enrichment activities. Having suitable outlets available can make a huge difference.
Redirect Onto Toys
If your puppy starts biting hands, clothes or feet, calmly redirect them onto a toy.
Keep toys accessible around the house so you’re prepared when those sharp teeth appear.
Reward Calm Behaviour
It’s easy to focus on what we don’t want, but puppies learn best when we reinforce what we do want.
Notice and reward moments when your puppy is settled, chewing their own toy or interacting gently.
Build in Rest Time
Many biting episodes are linked to tiredness.
Young puppies need far more sleep than most people realise, often 18-20 hours per day. Ensuring your puppy has opportunities for uninterrupted rest can dramatically reduce biting behaviour.
When puppy owners come to me asking for help with excess biting, my first question is always “are they getting enough sleep?’.
Use Food Enrichment
Licking, sniffing and chewing are calming activities.
Scatter feeding, snuffle mats, stuffed Kongs and food puzzles can help meet your puppy’s needs and reduce excess energy.
Manage the Environment
If your puppy repeatedly targets clothing, shoelaces or children, management is your friend.
Use baby gates, pens, leads indoors or create quiet spaces where your puppy can settle and make good choices.
Teach Appropriate Interaction
Reward your puppy for keeping four paws on the floor, choosing toys and engaging calmly with people.
The more opportunities they have to practise appropriate behaviours, the more those behaviours become habits.
The Most Important Thing to Remember
Puppy biting can feel relentless when you’re in the middle of it, but it is a normal developmental stage.
Your puppy isn’t trying to be difficult. They’re learning how to live in our world while managing excitement, frustration, tiredness and teething discomfort.
With patience, consistency and positive guidance, this phase will pass by about 6 months old.
Focus on providing appropriate outlets, rewarding the behaviours you want to see and helping your puppy succeed. Before long, those sharp puppy teeth will be a distant memory, and you’ll have laid the foundations for a confident, well-mannered adult dog.
If you’re struggling with puppy biting, remember that you’re not alone. It’s one of the most common challenges puppy owners face, and with the right support, it gets better.
