Puppy Parent Survival Guide
Day 1: The First 72 Hours

If today feels overwhelming, that is expected.

Veterinary behavior research consistently shows that the first 72 hours after a puppy leaves their litter are a major neurological and emotional adjustment period.

Your puppy has experienced:

• separation from their mother

• loss of littermates

• sudden environmental change

This activates the stress response system, even in confident puppies.

What matters most today

Not training.
Not correction.
Not expectations.

The priority is regulation and safety.

Veterinary behaviorists agree that puppies adjust best when their environment is:

• predictable

• calm

• low stimulation

Evidence-based focus for Day 1

1. Calm environment
Quiet spaces help regulate cortisol (the stress hormone).

2. Simple routine
Potty → Eat → Sleep
Repetition reduces anxiety.

3. Protected rest
Young puppies require 18–20 hours of sleep per day for healthy brain development.

4. Limited exposure
Too much novelty too fast increases stress rather than confidence.

How to measure success today

Behavior professionals recommend using biological needs as the Day-1 benchmark:

• Did your puppy eat?

• Did they eliminate appropriately?

• Did they rest?

• Did they experience calm, positive interaction?

If yes, adjustment is happening.

Important reassurance

Crying, clinginess, or restlessness tonight are normal stress responses, not signs of failure.

Structure and predictability allow the nervous system to settle.

You are laying the foundation for long-term emotional stability.
