If your new puppy treats your hands, ankles and sleeves like chew toys, you are not doing anything wrong, and you do not have a "bad" puppy. Mouthing is how puppies explore the world, play with their littermates and soothe sore gums while their adult teeth come in.
The goal is not to stop your puppy from ever using their mouth. It is to teach them that human skin is off limits, that toys are the best thing to bite, and that biting makes the fun stop. Yelling, tapping the nose or holding the mouth shut tends to make things worse: it can turn biting into a rough game or teach your puppy to be wary of hands.
Why puppies bite so much
- Play: puppies wrestle and bite each other as their main way of playing. Your hands look like the nearest littermate.
- Teething: most puppies lose their baby teeth and grow adult teeth over several months, and chewing seems to feel good.
- Overtiredness: a puppy who has been awake too long often gets wilder and bitier, not sleepier. The evening "zoomies" with sharp teeth are a classic sign.
- Attention: if biting your sleeve always gets a reaction, it becomes a reliable way to start a game.
- Learning bite pressure: puppies learn how hard is too hard through feedback from other dogs and from us.
Step 1: Always have a toy within reach
Keep soft toys, rope toys and safe chews in every room where your puppy spends time. When your puppy starts mouthing you, calmly offer a toy and make it move. Wiggle it along the floor, drag it away like prey or play a gentle game of tug. Most puppies prefer something that moves to a still hand.
Praise warmly when they bite the toy. You are not just stopping a behavior, you are showing them the right outlet.
Step 2: Make biting skin end the game
Your puppy needs clear feedback that teeth on skin stops the fun. Here is a calm way to give it:
- If teeth touch your skin hard, stop moving and say a short word in a neutral voice, such as "Oops" or "Ouch".
- Pull your hands in against your chest and turn away for a few seconds.
- When your puppy calms down, offer a toy and resume play.
- If they come straight back to biting you, end the game: stand up and step away, or calmly step over a baby gate for 20 to 30 seconds.
Some guides recommend a high pitched yelp. For some puppies it works; others find it exciting and bite more. If yelping winds your puppy up, use the quiet "Oops" and step away instead.
Step 3: Teach gentle mouths gradually
Many trainers teach puppies to soften their bite before stopping mouthing on people altogether. In practice this means reacting first to the hardest bites and, over a few weeks, to firmer and then lighter pressure, until any teeth on skin ends the game. Children should not take part in this exercise. Teach kids to play with puppies using toys only.
Step 4: Use calm time outs, not punishment
A short break is a powerful message for a social puppy. The key is to keep it calm and boring:
- Use a puppy pen, a gated kitchen or a crate your puppy already likes, with a chew toy inside.
- Keep breaks short, from 30 seconds to a couple of minutes. The point is to interrupt the cycle, not to punish.
- Do not scold on the way in. A time out works because the fun stops, not because your puppy is frightened.
- If your puppy falls asleep in the pen within minutes, they were probably overtired. That tells you something useful about your schedule.
Step 5: Prevent the overtired puppy
Young puppies need a lot of sleep. Many guides suggest that young puppies sleep for well over half of every 24 hours. When they miss naps, biting usually gets worse. A simple rhythm helps:
- Wake up, potty break.
- Play, training or exploring for a short time (shorter for younger puppies).
- Potty break, then a calm chew and a nap in a quiet space.
If you notice the evening "crazies" start around the same time each day, schedule a calm activity and a nap just before. A lick mat or a stuffed food toy can help a puppy wind down.
Step 6: Teach a few useful alternatives
Short training sessions give your puppy's brain a job and teach behaviors that are incompatible with biting:
- Sit for attention: reward sits generously, especially when your puppy approaches you. Sitting and biting ankles are hard to do at the same time.
- Hand target: hold two fingers near your puppy's nose; when they touch them with their nose, mark "Yes!" and reward. Hands become something to touch gently, not bite.
- Find it: toss a treat on the floor and say "Find it!" It is a great way to redirect a puppy who is starting to get mouthy.
Ankle biters and sleeve grabbers
If your puppy attacks your feet as you walk, stop moving the moment they latch on. Moving feet are exciting; still feet are boring. Then toss a toy ahead of you so they have something better to chase. For a while, keep a toy in your pocket and offer it before your puppy reaches your ankles. Some people tie a toy to a string and drag it behind them as they walk through the house.
What not to do
- Do not yell, hit, tap the nose, hold the mouth shut or push your thumb into your puppy's mouth. These can frighten your puppy and damage trust.
- Do not play rough hand wrestling games, which teach that hands are toys.
- Do not pull your hand away fast when bitten if you can help it. Sudden movement can make the game more exciting. Go still instead.
When to get help
Normal puppy mouthing is loose and playful, with a wiggly body. Talk to your veterinarian and a certified professional trainer if your puppy bites with a stiff body, growls while guarding food or toys, seems frightened when touched, or if the biting is getting harder as your puppy gets older rather than softer. Ask your veterinarian too if your puppy seems in pain when chewing.
How long it takes
Most puppies mouth less as they grow and learn, but it does not happen overnight. Stay consistent, make sure everyone in the house follows the same rules, and celebrate small wins: a softer bite, a quicker switch to the toy, a calmer evening.
