How to Stop a Puppy from Biting: 7 Training Tips That Actually Work

Last Updated on January 29, 2025 by Dogs Vets

Why Puppies Bite (It’s Not Aggression!)

Puppies bite for 3 key reasons:

1. Teething: Between 3–6 months, puppies lose baby teeth, and chewing relieves gum pain.
2. Play Behavior: Biting mimics littermate interactions.
3. Exploration: Puppies use their mouths to investigate the world, like human babies.

According to a 2023 study in Applied Animal Behavior Science, 98% of puppies bite during play, but only 12% of owners address it correctly.

7 Training Tips to Stop Puppy Biting

1. Redirect with Chew Toys (The Swap Trick)

• What to Do: When your puppy bites skin, say “OUCH!” and immediately offer a chew toy.
• Why It Works: Teaches puppies to bite toys, not hands.
• Best Toys:
  • KONG Puppy: Stuff with frozen peanut butter (xylitol-free).
  • Nylabone Teething Ring: Soothes sore gums.

2. Use the “Time-Out” Method

• Step-by-Step:
  1. Say “NO BITING” in a calm, firm tone.
  2. Stand up, turn your back, and leave the room for 30 seconds.
  3. Return and resume play if the puppy is calm.
• Science Backing: A 2021 study in Journal of Veterinary Behavior found time-outs reduce biting by 63% in 2 weeks.

3. Teach Bite Inhibition with Yelping

• How to Do It: Mimic a puppy’s pain yelp (“YIP!”) when bitten too hard.
• Pro Tip: Gradually increase your sensitivity—yelp for softer bites over time.
• Why It Matters: Puppies learn to control bite force, preventing future injuries.

4. Reward Calm Behavior

• Treat Timing: When your puppy licks instead of bites, say “YES!” and reward with a treat.
• Best Rewards: Small, soft training treats (e.g., Zuke’s Mini Naturals).
• Key Insight: Positive reinforcement builds trust faster than punishment.

5. Socialize with Other Puppies

• Puppy Playdates: Let your puppy interact with vaccinated, well-behaved dogs.
• Benefits: Adult dogs correct biting naturally (e.g., walking away or growling).
• Warning: Avoid dog parks until vaccinations are complete.

6. Freeze a Washcloth for Teething Relief

• DIY Solution: Soak a washcloth in low-sodium broth, freeze, and let your puppy gnaw.
• Why It Works: Cold numbs gum pain, and chewing satisfies the urge to bite.

7. Use the “Off” Command

• Training Steps:
  1. Hold a treat in your closed fist.
  2. When your puppy mouths your hand, say “OFF.”
  3. Reward when they stop biting.
• Advanced Move: Practice with higher-value items (e.g., bully sticks).

Common Mistakes That Make Biting Worse

1. Yelling or Hitting: Increases fear and aggression.
2. Playing Rough: Encourages “mouthy” behavior.
3. Ignoring the Behavior: Puppies assume biting is acceptable.

When to Worry: Signs of Aggression vs. Normal Biting

If you see aggression: Consult a certified dog behaviorist immediately.

Prevention Tips

• Exercise: A tired puppy is less likely to bite. Aim for 5 minutes of play per month of age, twice daily.
• Puppy-Proofing: Remove tempting items (shoes, cords) to avoid reinforcing “chew = fun.”
• Routine: Feed, play, and nap at consistent times to reduce overstimulation.
