Day 5: Biting, Teething & Arousal

Puppy biting is one of the most common concerns in the first weeks home.
It is also one of the most misunderstood behaviors.

From a veterinary behavior standpoint, early puppy biting is developmentally normal and expected.

What science tells us

Young puppies explore their environment using their mouths.
Biting behavior is influenced by:

• teething discomfort

• immature impulse control

• overstimulation

• fatigue

At this age, puppies do not yet have the neurological ability to regulate arousal independently.

Biting increases when the nervous system is overloaded.

Today’s priority: Prevent escalation

Veterinary behaviorists emphasize management over correction during this stage.

Evidence-based strategies for Day 5:

• Limit high-arousal play
Rough or fast movement increases mouthiness.

• Protect rest cycles
Overtired puppies bite more intensely and more frequently.

• Redirect early
Provide appropriate chew items before biting escalates.

Why punishment does not help

Research shows that aversive responses:

• increase stress hormones

• delay learning

• can damage trust

Instead of reducing biting, punishment often intensifies arousal.

Calm interruption and redirection are more effective for developing puppies.

What to do in the moment

• Pause interaction briefly

• Reduce stimulation

• Redirect to a chew or settle activity

• Encourage rest if biting persists

Biting that continues despite redirection is often a sign the puppy needs sleep.

How to measure progress

Progress is gradual.

Signs of improvement include:

• shorter biting episodes

• easier redirection

• improved recovery after rest

These changes happen as the nervous system matures.

Professional reassurance

Biting decreases naturally with:

• neurological development

• consistent structure

• appropriate rest

Your role is not to stop biting instantly, it is to guide your puppy safely through a normal developmental stage.
