Your Puppy's First Three Months: The Adaptation Stage
The first three months at home shape your puppy's habits, confidence and bond with you. This guide covers settling in, house-training, crate and alone-time skills, early handling and the vaccination timeline, so those busy early weeks feel structured rather than overwhelming.

Quick answer

Your Puppy's First Three Months: The Adaptation Stage
In the first three months at home, focus on routine, gentle house-training, and building your puppy's confidence. Feed at set times, take frequent toilet breaks, reward the behaviour you want, and keep experiences positive. Book the puppy's vaccination course early and avoid high-risk dog areas until your vet says it is safe.

| Situation | Do now |
|---|---|
| Mild / stable at home | Follow steps in this guide and monitor for 12–24 hours |
| Not eating, hiding, or clear pain | Same-day vet (species-savvy if exotic) |
| Breathing hard, collapse, continuous distress | Emergency vet now |
| You are unsure after reading | Call a clinic with your notes rather than waiting days |
Build a predictable routine
Puppies thrive on rhythm. Feed at the same times each day, alternate short bursts of play with real rest, and keep a consistent bedtime. A tired puppy that has had enough sleep behaves far better than an overstimulated one , young puppies need up to 18 hours of sleep a day. Write a rough daily plan the household can follow so everyone responds the same way.

House-training that works
Take your puppy to the toilet spot after every sleep, meal, play session and drink , that can be every hour or two at first. Go with them, wait, and reward calmly the moment they finish. Accidents are part of learning: clean them with an enzyme cleaner so no scent remains, and never punish after the fact, which only teaches fear. In a high-rise flat, a balcony pad or an indoor toilet area can bridge the gap between outdoor trips.
Crate and alone-time skills
A crate or pen used kindly becomes a safe den, not a cage. Feed meals near it, toss treats inside, and let your puppy choose to enter. Build alone time in tiny steps , a few seconds, then minutes , so your puppy learns that being alone is normal and you always come back. This early groundwork is the best protection against separation anxiety later.

Make the crate a positive, optional space , never a punishment.

Gentle handling and early learning
Get your puppy comfortable being touched all over: paws, ears, mouth and belly, paired with treats. This makes vet visits, nail trims and grooming far easier for life. Introduce the collar, lead and, if you use one, a harness indoors first. Keep first lessons , name recognition, sit, coming when called , short and fun.

Keep training sessions short, upbeat and reward-based.
Health and vaccinations
Your vet will set a vaccination schedule, usually a course of injections through the early months, plus regular worming and flea prevention. Until the course is complete, avoid places where unvaccinated dogs gather, but do not keep your puppy isolated , carry them to see the world safely. Book a health check soon after arrival so any issue is caught early.
