How to Stop a Puppy from Biting

Puppies explore the world with their mouths, and those needle-sharp teeth are part of the package. Biting is normal — but it needs a consistent response or it becomes a habit.

The most important lesson is bite inhibition: teaching the puppy how hard is too hard. When teeth touch skin, let out a high-pitched "ouch," stop the game, and ignore the puppy for a few seconds. That mimics how puppies learn limits from their littermates.

Then redirect. Every time the puppy mouths, offer a proper chew toy instead. Puppies teethe for months, so they genuinely need to chew — your job is pointing that energy at toys, not hands.

Keep play calm, avoid wrestling games that rile a puppy up, and make sure the puppy is getting enough sleep. Overtired puppies bite harder and more often.

Quick Q&A

When does puppy biting stop? Most puppies improve dramatically once adult teeth come in, around six months.

Is biting a sign of aggression? Almost never in a young puppy — it's play and teething, not aggression.

What if the "ouch" method doesn't work? Be consistent, and end play entirely for a short timeout. Excitement makes puppies mouth more.
