Puppy's First Year — The Complete UK Owner's Checklist

Introduction

The first year of your puppy's life determines everything. If you miss the critical socialisation window (weeks 3-16), your puppy may suffer lifelong anxiety, fear, and behavioural problems. If you skip vaccinations, your puppy risks deadly diseases. If you don't get insurance immediately, pre-existing conditions won't be covered later.

This isn't meant to scare you — it's meant to empower you with a clear month-by-month checklist so you don't accidentally skip anything important. Follow this guide and you'll have a healthy, confident, well-socialised dog.
