What belongs on the checklist
Include everyday surfaces, household and street sounds, people with different appearances and movement, gentle body handling, calm healthy animals, short journeys, and places your dog will need to navigate later.
A checked box should mean your puppy had a manageable experience—not merely that the event happened. Repeat easy, positive experiences instead of rushing through the list once.
How to introduce something new
- Begin far enough away or quietly enough that your puppy can observe without freezing or trying to escape.
- Pair the sight, sound or handling with food, play or calm praise your puppy enjoys.
- Allow your puppy to approach or retreat; do not pull them toward the experience.
- Finish while your puppy is still coping well.
- Repeat later before making the experience louder, closer, longer or more complex.
Signs the session is too difficult
Increase distance or stop when your puppy repeatedly turns away, refuses food, freezes, crouches, tucks the tail, tries to hide, or cannot disengage. The goal is not to make a frightened puppy endure the situation.
Vaccination and safe exposure
Early social development overlaps with the vaccination period. Disease risk varies by location and lifestyle, so ask your veterinarian which environments and contacts are appropriate. Controlled options may include being carried, observing from a clean surface, visiting known homes, and meeting healthy vaccinated dogs selected for calm behavior.
