Those needle-sharp puppy teeth can draw blood and shred sleeves — but biting is completely normal puppy behavior, and it's very fixable. The goal isn't to stop your puppy from ever mouthing (that's how they explore the world); it's to teach them to be gentle and to redirect onto appropriate things. Here's how.
Why puppies bite — it's normal
Puppies bite to explore, to play, because they're teething, and because it gets a big reaction from you (which, to a puppy, is fun). Understanding that it's developmental — not aggression — helps you respond calmly instead of getting frustrated.
The core technique: yelp, stop, redirect
- When those teeth touch your skin, let out a high-pitched 'ouch!' and immediately stop all movement and play
- Withdraw attention for 10-20 seconds — turn away or briefly leave. This teaches that biting ends the fun
- The instant they're calm, offer a chew toy and praise them for biting that instead
- Repeat consistently — every person in the house must do the same thing
What NOT to do
- Don't yank your hand away fast — it looks like a game and triggers the chase instinct
- Don't physically punish, hit, or hold their mouth shut — it creates fear and can make biting worse
- Don't allow rough hand-play (using your hands as toys teaches the opposite of what you want)
Nylabone Puppy Chew Toy
Redirection only works if you always have something better to offer, and a softer puppy-formulated Nylabone gives teething gums a durable, dog-safe target instead of your hands. Keeping one within reach makes the "stop, then redirect" step quick and consistent every time those needle teeth come out.

Be calm, be consistent, and always give them an acceptable outlet. Bite inhibition is one of the most important things a puppy learns, and with this gentle method most puppies improve dramatically within a couple of weeks.
Frequently asked questions
At what age do puppies stop biting?
Most puppies bite hardest during teething, which runs from roughly three to six months, and mouthing usually eases as adult teeth come in and bite inhibition is learned — often around six to seven months. Consistent training speeds this up considerably. If it doesn't improve or biting seems aggressive rather than playful, ask a trainer or your veterinarian for guidance.
Is puppy biting a sign of aggression?
In the vast majority of cases, no — puppy nipping is normal developmental behavior driven by play, exploration, and teething. True aggression is different and usually comes with stiff body language, growling, and a clear intent to warn. If you're worried about the context or intensity, consult a qualified trainer or your vet.
Why does my puppy bite more in the evening?
Many puppies get a burst of hyper, nippy energy in the evening — often called the "witching hour" or zoomies — usually because they're overtired rather than under-stimulated. A calm wind-down routine, a chew toy, and encouraging a nap often help more than more play. Overtired puppies bite harder, so rest is key.
Should I let my puppy bite during play?
Gentle mouthing is part of how puppies play, but you want to teach that teeth on skin ends the fun immediately. Redirect onto a chew toy every time, and never use your hands as toys, since that teaches the opposite of what you want. The goal is bite inhibition — a soft mouth — not zero mouthing overnight.
