Puppy Biting Phase: How Long Does It Last?

The Puppy Biting Phase Explained

Puppy biting is normal behavior, not aggression. Understanding why it happens helps you respond effectively.

Why Puppies Bite

Puppies explore the world with their mouths. Biting during play is how they learned to interact with littermates. Teething (3-6 months) adds discomfort that makes mouthing more intense.

Timeline

  • 8-12 weeks: Peak biting phase as puppies settle into new homes
  • 3-4 months: Teething begins; biting may increase
  • 4-6 months: Adult teeth come in; biting should decrease
  • 6+ months: Most puppies outgrow mouthing with consistent training

What Works

Redirect to a chew toy the moment teeth touch skin. Say "ouch!" in a high-pitched voice and withdraw attention for 10 seconds. Never punish — it creates fear, not learning. Reward gentle play enthusiastically.

When to Seek Help

If biting intensifies after 6 months, involves growling, or seems driven by fear rather than play, consult a certified dog trainer or behaviorist.
