# Week 16: the last shots and the first real walk

The series ends, the ground opens up, and the socialization window narrows.

Week 16. The series ends, the ground opens up, and the socialization window narrows.

## Final combination shot

About a week after it, the puppy is protected and can walk on public ground.

> **Parasite prevention.** Heartworm and flea and tick prevention start around now in most areas. Ask which products suit your region.

## First walks

Five minutes per month of age, on grass and quiet streets. Sniffing counts as exercise.

### Last of the window

New people, new dogs, new places this week. The easy socialization period is closing.
