If your 9-week-old just sank his needle teeth into your hand for the 40th time today, you're not doing anything wrong, and he isn't turning mean. Puppies explore the world with their mouths, and right around 3 to 6 months old they're also pushing sore teething gums against whatever they can reach. Your hands are right there. So are your ankles when you walk by, and the hem of your sweatpants when you sit down. The good news is that puppy biting is one of the most fixable things you'll deal with, and you don't need any special gear to work on it.
Why puppies bite in the first place
Two things are happening at once. Baby teeth come in and then start falling out, so the gums ache and chewing brings some relief. On top of that, mouthing is how a young dog plays and figures out how the world feels.
Litters teach this naturally. When one pup bites a sibling too hard, the other yelps and quits playing, and the biter learns to soften up. Your puppy left that classroom early, so now you're the one giving the feedback. That's the whole job. You're teaching him that human skin is delicate and teeth mean the fun stops.
How to redirect the biting, step by step
The pattern you want is the same every time. Teeth touch skin, the game pauses, a toy shows up. Keep a chew toy in every room so you're never scrambling for one when the needle teeth come out.
- Keep a toy within reach Stash a rope or rubber chew in each room and one in your pocket. When your puppy heads for your hand, you want the toy ready before the teeth land.
- Freeze your hand The second you feel teeth, stop moving. A hand that jerks away looks like a fleeing squirrel and gets chased harder. Going still makes it boring.
- Trade for the toy Slide the chew toy in front of his mouth so he can grab it instead. The moment he bites the toy and not you, tell him 'good' in a warm voice so he connects the toy with the praise.
- Mark the miss with a short sound If he keeps going for skin, give a calm 'ouch' or 'nope' and take your hand out of the game for a few seconds. You're copying the sibling who quit playing.
- End the game if the mouth stays wild Stand up, step over a gate, and give him 2 to 3 minutes to settle. Half the time an overtired puppy just needs the nap he won't take on his own.
- Reward the calm mouth When he chews his toy quietly or licks instead of bites, that's the moment to praise and pet. Puppies repeat whatever gets them attention, so catch the good stuff early.
Things that make puppy biting worse
A few common reactions feel natural but teach the opposite of what you want.
- Pulling your hand back fast. Quick movement turns your fingers into a toy and makes the chase more fun.
- Rough hand play or wrestling with bare hands. It tells him your hands are chew toys, then you're frustrated when he treats them that way.
- Yelling or physical corrections like grabbing his muzzle. These scare a puppy or rev him up more, and some pups start biting harder or get jumpy around hands.
- Only reacting to the hard bites. Wait too long and the soft mouthing you ignored has already grown into a real chomp. Give feedback while it's still gentle.
- Different rules from different people. If one person wrestles and another says no, the puppy stays confused for weeks longer.
How long does this last
Most puppies grow out of the worst of it by 5 to 6 months, once the adult teeth are in and the sore gums settle. If you stay consistent, you'll see the biting ease off week by week, with a few backslides on days he's overtired or wound up. It helps to run him tired earlier in the day and to keep a frozen chew on hand for the aching gums, which takes a lot of pressure off while you wait it out.
Nipping that comes with a stiff, frozen body, a low growl, or a hard stare, especially when you get near his food bowl, a chew, or his bed.
Talk with your vet or a certified trainer if the biting seems fearful, keeps breaking skin past the young-puppy stage, or isn't improving at all after a few weeks of steady redirecting.

Common questions
Why does my puppy bite me and not everyone else?
Usually it's about how you move and react. Puppies bite the person who plays the roughest, moves the fastest, or gives the biggest reaction, since all of that reads as a great game. Kids and quick-moving hands get bitten most. Try slowing your movements around him and make sure everyone reacts the same calm way.
At what age do puppies stop biting?
Most puppies bite hardest between 3 and 5 months while they're teething, and it usually calms down a lot by 6 months once the adult teeth are in. Consistency speeds it up. If your puppy is past 6 months and still biting hard, it's worth a chat with a trainer.
Is it normal for my puppy to bite my hands and feet this much?
Yes, it's one of the most common things new puppy owners deal with. Hands and feet move, and moving things are irresistible to a teething puppy. It's normal play as long as he stays loose and wiggly, not stiff or growling. Redirect to a toy and it fades with time.
How do I stop my puppy from biting my clothes and pant legs?
Stop walking and stand still, since a swinging pant leg is a moving target he can't resist. Wait for him to let go, then hand him a toy to carry or chew. Keeping a toy in your pocket for trips across the house helps a lot. Dragging a puppy while he's latched on just turns it into tug.
Does saying ouch actually stop puppy biting?
It works for some puppies and revs others up. A calm, short 'ouch' plus ending the game for a few seconds is what teaches him, and the pause matters more than the sound. If your 'ouch' makes him bite more, skip it and just go quiet, stand up, and step away instead.
