Puppy nipping is completely normal, and completely trainable. Here's how to teach gentle mouths and save your hands.
Why puppies bite
Puppies explore the world with their mouths, and biting is how they play and learn. It peaks during teething, when sore gums crave pressure. This is a completely normal developmental stage — the goal isn't to eliminate mouthing overnight, but to teach your puppy that human skin is off-limits.

Teach bite inhibition
In a litter, puppies learn from each other that biting too hard ends the fun. You can mimic this: when a nip hurts, give a short, calm "ouch" and stop the interaction for a few seconds. Rewarding gentle play and pausing when teeth get sharp teaches your puppy to control the pressure of their mouth.
Redirect to appropriate chews
A biting puppy is often just looking for something to chew. Keep chew toys within reach and redirect every nip onto a toy. A rugged, chewable [KONG Classic](/products/kong-classic-dog-toy) — stuffed and frozen — soothes teething gums and gives those needle teeth a proper target. When your puppy chooses the toy, praise them warmly.
Manage energy and overtired biting
Much of the worst biting comes from an overtired, overstimulated puppy who needs a nap, not more play. Watch for the "land shark" mood and offer a quiet rest in a crate or pen. Regular short play sessions, sniffy walks, and enforced downtime prevent the frantic biting that comes with exhaustion.
What not to do
Skip physical corrections like tapping the nose or holding the mouth shut — they can make biting worse or teach your puppy to fear hands. Rough play with your hands sends mixed signals, too. Calm redirection, consistency, and plenty of chew outlets are what turn a nippy puppy into a gentle-mouthed dog.
