Bringing home a new puppy is an exciting experience, but along with the cute cuddles and wagging tails comes a common challenge: biting. If you’re a new dog owner, you might find yourself wondering, How to train a puppy not to bite?
Puppy biting is completely normal, but that doesn’t mean you should ignore it. If left untrained, that playful nibble can grow into a painful or even dangerous habit. The good news is—you can teach your puppy to stop biting. This guide will show you exactly how to do it, using simple, effective, and kind methods.

Is It Normal for Puppies to Bite?
Yes, it is completely normal for puppies to bite, and it’s an essential part of their development. Here’s a detailed explanation to help you understand the reasons behind puppy biting and how to manage it:
1. Natural Puppy Behavior
Puppies explore the world with their mouths. Just like human babies, they go through a teething phase during which biting helps soothe their gums. This phase typically begins around 3 weeks of age and can last until they’re about 6 months old. Biting is also a way for puppies to play and interact with their environment and littermates. When playing with siblings, they bite each other — and this teaches them bite inhibition (i.e., how to control the strength of their bite).
2. Communication and Play
Biting is one of the primary ways puppies communicate and initiate play. If you observe a group of puppies, you’ll notice they often nip each other, wrestle, and growl playfully. When your puppy bites you, they may be trying to engage in similar playful behavior, especially if they are not yet fully socialized or separated from their litter too early.
3. Teething Discomfort
When puppies are teething, they experience discomfort and a strong urge to chew. Biting helps relieve the pressure and pain in their gums. During this stage, you may notice your puppy biting everything — hands, furniture, shoes — whatever they can get their mouth on. This is not aggression, but a teething-related need that needs redirection with appropriate chew toys.
4. Learning Boundaries
Through gentle biting and feedback from their siblings or mother, puppies learn what is acceptable. If a bite is too hard, another puppy will yelp and stop playing, which teaches limits. When humans adopt puppies, it becomes our responsibility to teach them boundaries — letting them know that human skin is off-limits. Ignoring this can lead to poor bite inhibition as they grow older.
5. Preventing Aggression Early
Puppy biting is not typically a sign of aggression. However, if biting is encouraged or not properly addressed, it can lead to unwanted behaviors later. Early socialization, obedience training, and consistent responses help ensure the biting remains a phase and doesn’t evolve into a behavioral problem.
6. How to Manage Puppy Biting
- Redirect biting to safe toys (especially those made for teething).
- Avoid physical punishment, as it can lead to fear or aggression.
- Use positive reinforcement: reward calm behavior and gentle play.
- Socialize your puppy with other vaccinated, well-mannered dogs.
Why Do Puppies Bite?
Puppies bite for a variety of natural, instinctive, and developmental reasons. While it can be frustrating or even painful for new pet parents, understanding the underlying causes helps in managing and redirecting the behavior appropriately. Here’s a detailed breakdown of the main reasons puppies bite:
1. Exploration and Curiosity
Puppies explore the world using their mouths just as human babies use their hands. Everything is new and interesting — from your fingers to your shoes. Biting, chewing, and mouthing objects is part of how they learn about their surroundings. It helps them identify textures, shapes, and even taste. This behavior is normal exploratory behavior, not an attempt to harm.
2. Teething and Gum Discomfort
Between 3 weeks and 6 months of age, puppies go through a teething phase. Their baby teeth fall out, and adult teeth begin to come in. This causes gum irritation, which makes them want to chew and bite on anything to relieve the discomfort. During this period, puppies may seem more bitey than usual. Chewing and biting provide relief, much like how teething toys help infants.
3. Playfulness and Social Learning
Biting is an important part of how puppies play with each other. When they’re with their littermates, they nip and wrestle as a form of play. Through these interactions, they learn bite inhibition — controlling the force of their bite. If one puppy bites too hard, the other might yelp and stop playing, sending the message that the bite was too rough. When puppies come into human homes, they may try the same behavior during play. They’re not being aggressive — they’re simply trying to play the only way they know.
4. Attention-Seeking Behavior
Puppies are clever and quickly learn what gets your attention. If biting your hands, feet, or clothes consistently gets a reaction (whether you yell, pull away, or chase them), they might continue doing it as a way to engage you. Even a negative response can reinforce the behavior, making biting an effective way for your puppy to demand attention.
5. Lack of Proper Socialization
Puppies that have not spent enough time with their litter or have not been exposed to different people, dogs, or situations may not have learned proper boundaries. Without early socialization, they may bite too hard or not recognize when their behavior is inappropriate. Teaching bite inhibition becomes even more critical in these cases, as they missed that lesson from their mother or siblings.
6. Overstimulation or Excitement
Sometimes, puppies bite when they’re overly excited or overstimulated. For example, during rough play, when meeting new people, or in new environments, their arousal level increases — and biting may be an impulsive way to release that energy. In these moments, it’s important to help them calm down and transition to more appropriate behaviors.
7. Fear or Frustration
Although less common in very young puppies, some may bite when they feel afraid, threatened, or frustrated. If a puppy is cornered, handled too roughly, or has a negative experience (like a loud noise or painful incident), biting might be a defensive reaction. This kind of biting needs careful handling, as it can evolve into behavioral issues if not addressed compassionately and with proper training.
Knowing the cause helps you respond in the right way.
How to Train a Puppy Not to Bite: 10 Proven Techniques
Let’s break down the best strategies to stop puppy biting without shouting or punishing. These methods are gentle, effective, and backed by trainers.
1. Teach Bite Inhibition Early
Bite inhibition is your puppy’s ability to control how hard they bite. Puppies learn this from their mother and siblings. When they bite too hard during play, the other pup yelps and stops playing. This teaches them boundaries.
You can mimic this by reacting similarly. If your puppy bites too hard, say “Ouch!” in a high-pitched voice and stop playing for a few seconds. This teaches them that biting means the fun stops.
2. Use the “Yelp” Method
As mentioned above, make a short, sharp sound like “Ow!” or “No!” to let your puppy know they hurt you. Then ignore them for 10–15 seconds. This mimics what happens in the dog world and helps them learn quickly.
Consistency is key—use the same sound and response each time.
3. Redirect the Bite to a Toy
If your puppy keeps biting your hands or feet, redirect their attention to a chew toy. Keep a soft plush toy or rope toy handy during playtime. As soon as they go to bite, offer the toy instead. Praise them when they chew on it.
This teaches them what’s okay to bite and what’s not.
4. Stop Play When Biting Starts
Puppies need to understand that biting leads to the end of play. If your puppy bites during playtime, immediately stop interaction and walk away for a minute or two.
This gives them a clear message: no biting = more fun.
5. Reward Calm Behavior
Positive reinforcement is one of the most powerful training tools. When your puppy plays gently, doesn’t bite, or responds to commands, reward them with praise, treats, or affection.
This builds good habits and makes them want to behave well.
6. Avoid Rough Play That Encourages Biting
Wrestling or hand-play can overstimulate a puppy and make them think biting is part of the fun. Avoid using your hands as toys. Instead, use tug ropes or balls.
Play in ways that encourage calm and controlled behavior.
7. Offer Plenty of Chew Toys
Teething puppies need to chew. Make sure they have access to a variety of safe chew toys. Rotate them to keep things interesting.
Try:
- Frozen carrots
- Teething rings made for dogs
- Durable rubber toys (like KONG)
This reduces their urge to bite people.
8. Use Timeouts When Needed
If your puppy bites repeatedly, even after corrections, use a timeout. Calmly place them in a quiet, boring space like a puppy-safe room or crate (just for 30 seconds to 1 minute).
Avoid yelling or scaring them—this isn’t a punishment, it’s a reset.
9. Be Consistent With Training
Everyone in your household should respond to biting in the same way. Inconsistency confuses your puppy and slows learning. Make sure kids, family members, and visitors follow the same rules.
Consistency leads to faster results.
10. Consider Puppy Socialisation Classes
Puppy classes are a great way to teach bite inhibition and polite behavior. Being around other puppies helps them learn limits during play. Plus, you get professional guidance from a trainer.
Early socialisation also helps prevent fear and aggression later in life.
What Not to Do When Your Puppy Bites
Some methods can do more harm than good. Here’s what to avoid:
- Don’t hit, slap, or tap their nose – this creates fear and breaks trust.
- Don’t yell or scream – loud voices often make puppies more excited or scared.
- Don’t encourage biting as a joke, like letting them chew on your fingers.
- Don’t give attention after biting – even negative attention can reinforce the behaviour.
Focus on calm, clear, and consistent training instead.
How Long Does It Take to Stop Puppy Biting?
There’s no fixed timeline, but most puppies learn to reduce biting by the time they’re 6 months old with consistent training. Some high-energy or teething breeds may take longer.
Patience is crucial. Progress may be slow at first, but every week gets better.
When to Get Help From a Dog Trainer or Vet
If your puppy’s biting is:
- Aggressive (growling, lunging, snapping)
- Frequent and intense
- Not improving with training
…it’s time to talk to a professional. A certified dog trainer or behaviourist can assess your pup and guide you with personalised help.
Also, check with your vet if the biting started suddenly or seems linked to pain or medical issues.
Conclusion
Training your puppy not to bite takes time, consistency, and lots of patience—but the results are worth it. Remember, biting is natural for puppies, but it doesn’t have to be permanent. With the right techniques, you can teach your puppy how to interact gently and grow into a well-behaved, loving companion.
Start early, stay consistent, and use positive methods. Your puppy isn’t trying to be bad—they’re just learning how to be part of your world.
