How to Care for a Puppy: First Weeks at Home (Vet Guide)

Vet-reviewed via PetHealth+ · Last reviewed June 2026

The first weeks with a puppy set the foundation for life. Priorities are a **safe space** (crate or pen), a **predictable routine** for food and toilet breaks, **positive socialisation** during the critical early window, and a **vet visit** within the first few days for vaccinations, parasite prevention, and microchip checks.

Before arrival

Register with a local vet
Buy a collar and ID tag, lead, bed, food and water bowls, appropriate puppy food, toys, and grooming basics
Puppy-proof one area — secure cables, plants, and cleaning products
Decide on house rules (furniture, sleeping location) and agree as a household

First night and sleeping

Many puppies cry the first nights away from their litter. A crate or pen beside your bed (or a warm hot-water bottle and ticking clock in the pen) can help. Avoid rewarding midnight play — keep toilet trips calm and brief.

Feeding

Feed a complete puppy diet appropriate for breed size. Follow the manufacturer’s guide and adjust with your vet to maintain a healthy body condition — you should feel ribs with a light cover. Fixed meal times aid toilet training.

Toilet training

Take your puppy out:

Immediately after waking
After every meal
After play sessions
Before bedtime

Use the same spot, praise calmly when they go, and never punish accidents indoors — clean with enzymatic cleaner. Consistency beats punishment every time.

Health care in the first months

Your vet will schedule core vaccinations (typically starting around 8 weeks), worming, and flea/tick prevention. Discuss microchipping (legally required in many countries), neutering timing, and pet insurance while your dog is young and before pre-existing conditions develop.

Socialisation and training

The first months are a sensitive period for learning. Safely expose your puppy to:

Different people (ages, appearances, hats, uniforms)
Household noises (vacuum, doorbell)
Other vaccinated, friendly dogs
Various surfaces and gentle handling (paws, ears, mouth)

Keep experiences positive — pair new things with treats. Puppy classes run by reward-based trainers help both socialisation and basic cues.

Exercise — do not overdo it

Growing joints are vulnerable. Short, frequent play sessions beat long hikes. Your vet can advise on safe exercise limits for your breed.

Frequently asked questions

When should a puppy leave its mother?

Most puppies should stay with their litter until at least 8 weeks old — earlier separation can affect behaviour and immunity.

How often does a puppy need to toilet?

Very frequently — often after waking, eating, playing, and every 1–2 hours at first. Take them to the same spot and reward success.

When can a puppy go outside?

Balance socialisation needs with vaccine timing — your vet will advise on safe outdoor access in your area, often after initial vaccinations.

How much sleep does a puppy need?

Up to 18–20 hours a day for young puppies. Overtired puppies can become bitey and restless.
