3 key things

• “Education (10 minutes)” to make your hands less painful starting today
• “Ouch!” Practical ways to reduce the intensity and frequency of biting without “pushing” or “screaming”
• Criteria for classifying whether this is the puppy’s normal range or a signal for expert help

Hello, this is Human Bear. Puppy bites are really common.  Puppy nibbling is a natural process that combines teeth grinding, excitement, and play. The problem is that “common” doesn’t mean “should be tolerated.” Puppies use their mouths like hands. Biting is one of those expressions of intent. However, in many cases, the dog comes to the guardian without going through the intensity control learned from the mother, so it is often impossible to control the intensity or frequency.

So, let’s set the goal just like this: Not ‘completely 0’ within 3 days, but ① less pain ② less frequent ③ keeping the hands and clothes of the guardian.

Puppy bites, first distinguish between “normal range vs. danger signal”

Characteristics of normal biting (play, bruxism)

• When you get excited while playing, your mouth comes out first (especially in the evening/when you are tired)
• Good at “moving things” like hands/clothes/leads
• More frequent when the desire to chew (bruxism) increases

Immediate expert help recommendation signal (safety check)

• The skin is torn or severely bruised (repeatedly)
• Before the bite, the body stiffens and is accompanied by a fixed gaze, growling, and vigilance
• Rather than asking and letting go, it is often “grasping and shaking”
• Tries to bite while holding food, toys, and position (possibility to protect resources)
• It only appears strongly in certain people in the family

If the above applies, a safety plan + expert consultation is much faster and safer than trying to get through the internet.

3 key principles to help you get sick less in 3 days

1) Avoid using your hands as ‘toys’ (environment, management)

• During times when your puppy is likely to be excited inside the house (in the evening, after returning home), it is easy to control it by attaching a short leash.
• Reduce “excitement rush” by dividing the baby’s movement path with a fence and gate. Just make sure not to meet at once.
• Play with toys under the guidance of the guardian, but put them away at regular times. Start playing when you feel calm.

2) “Immediately” teaching actions to use instead of mouth (substitute actions)

• The opposite of biting is not “staying still,” but providing a place for the mouth to go (chewing).
• Place 2-3 chew toys “always within reach” (living room, bedroom, entryway).

3) Reduce the timing of speaking by lowering the excitement level

• When a puppy is excited, its ‘mouth’ comes out before its ‘head’. So cutting off play time is actually faster.
• There are many recommendations that a reward-based approach is safer and more effective in the long term.

* Note: There are materials that recommend reward-based training and that corporal punishment and strong correction can lead to risks such as anxiety, fear, and aggression.

[Today] 10-minute routine: 3 things a guardian should do when the bite begins

1) “Hands still + body fixed (1 second)”

When Puppy bites, you instinctively want to take your hand away. But those “fast-moving hands” actually turn on the hunting game switch.

• The moment of being bitten: Stop your hand and also stop your body (1 second)
• Sounds (“Ouch!”) often cause overexcitement, so be quiet

2) Immediately put “something to chew” in the mouth (alternative behavior)

Don’t end the bite with “don’t do it,” but provide a place for the mouth to go right away.

• Bring a toy or chewing gum quietly near your mouth
• When Puppy bites a toy: Praise immediately (shortly “good”) + play together for 2-3 seconds

3) 10 seconds “Keep your distance” (gentle mini timeout)

• If you keep reaching for your hand even with toys: Stand up quietly and walk 2-3 meters away
• Rather than closing the door or yelling, the key is to provide a short “experience of losing interest”

Today’s goal
① When bitten, the hand “stops” → ② The toy “comes out” → ③ If it continues, “interest disappears for 10 seconds”
Even if you do these three things consistently, there are many cases where the intensity (pain) decreases first.

[Day 2] Softening the “If you bite” rule (a real-life version of a timeout)

From day 2, the rules become clearer. However, it does not feel like a punishment, but rather as a “pattern.”

Rule: If you find your hand 3 times in a row, ‘play is over + mat’

1. Before play begins: Place one toy near the mat.
2. If the bite is repeated 3 times: End the play quietly and lead to the mat (1 snack is OK)
3. Stay on the mat for 10-20 seconds → briefly resume play

This routine teaches children to “stop playing when they get excited, and start again when they calm down.”

[Day 3] Routine for dealing with biting (clothes, leash) while walking or playing

Lead, biting pants = often a sign of overexcitability

• 1 minute before a walk: Have your child use their nose first by finding snacks (scattering 5 on the floor) in front of the house.
• Starts biting while walking: Stop immediately → Shorten the leash → Wait 2-3 seconds
• Moment of placement: 1 snack on the floor (If your mouth goes down to the floor, it’s easy to lose excitement)

In reality, stop-wait-bottom reward works better than “Stop!” for walking bites.

Points that often fail (7 worsening patterns)

1. Remove your hand and shake it (more fun)
2. “Ouch!” Yelling(Many Puppy’s excitement switches on)
3. Pushing, blocking with knees (recognized as a physical fight)
4. Use your hands like toys Say “no” only when you want to use them
5. Repeat “don’t bite” when there’s nothing to chew
6. Playing for a long time even though you are tired (hyperexcitability)
7. Each family has different rules (some people are allowed, some are prohibited)

There are indications that reward-based training is recommended and that punishment/strong correction may have a risk of side effects.

Summary box

Puppy nibbling involves management + alternative behavior + control of excitement rather than “discipline”.
The 3-day goal is not completely 0, but less pain (intensity↓) + less frequent (frequency↓).
If there are danger signs (growling/fixed stare/skin tearing), expert consultation for safety concerns is recommended.

Checklist

• □ 2-3 chew toys placed “within reach” throughout the home
• □ If you bite, stop your hand (1 second) → Provide a toy → If you continue, distance yourself for 10 seconds
• □ Divide daily play into 3 to 5 short sessions rather than 1 long session
• □ Family rules (allowed/prohibited) are the same
• □ Response to biting while walking is unified into stop-wait-bottom compensation

FAQ

Q1. If I scold a puppy for biting, will it be corrected quickly?

A. Even if it appears to be temporarily suppressed, it can have the opposite effect if anxiety and fear are mixed in. There are many guides recommending a reward-based approach.

Q2. “ouch!” Do I have to make a sound?

A. Some puppies stop, but many get more excited by the sound. First, try changing it to “Stop hand + replace toy + keep distance for 10 seconds”.

Q3. How do I take a timeout when the bite is severe?

A. Short and quiet methods such as “10 to 30 seconds distancing” are realistically more effective than long-term isolation. Slamming the door or shouting can actually be irritating.

Q4. Is there anything that can be done during the bruxism period?

A. Bruxism itself may be natural, but it is possible to change the habit by “chewing with your hands instead.” Please create a chewing routine.

Q5. When do I need expert consultation?

A. If the skin is torn, growling/fixed gaze/voluntary guarding is seen, or an unpredictably strong bite occurs, professional help is recommended for safety.
