Bringing Your New Puppy Home: Where to Start
The first month with a new puppy is one of the most important periods of their entire life. What happens in these early weeks lays the foundation for their long-term health, behaviour, and wellbeing. It can feel overwhelming — vaccinations, worming, socialisation, diet — but breaking it down into a clear timeline makes everything manageable.
This checklist covers everything a responsible owner should do in the first 30 days, based on current veterinary guidance in the UK.
Days 1 to 3: Arrival and Immediate Priorities
Book a Vet Appointment
Your very first action should be registering with a local vet and booking an appointment within 48 to 72 hours of bringing your puppy home. Many reputable breeders include a health guarantee that requires a vet check within this window. Your vet will assess your puppy's weight, hydration, heart, eyes, ears, skin, and overall condition. This initial examination also gives you the chance to ask questions and start a vaccination plan.
Set Up a Safe Space
Puppies experience stress when separated from their litter. A crate or pen with a warm blanket, a heartbeat toy, and low ambient noise helps ease the transition. Avoid overwhelming them with too many visitors or loud environments in the first few days.
Review What They Have Been Eating
Ask your breeder or rescue centre what food your puppy has been eating. Switching diets too abruptly causes digestive upset. Stick with their existing food for the first week, then transition gradually over seven to ten days if you plan to change brands.
Week One: Vaccinations and Parasite Control
Understanding the UK Vaccination Schedule
In the UK, puppies typically receive their first vaccination at eight weeks old, covering distemper, hepatitis, parvovirus, and leptospirosis. The second dose follows at ten to twelve weeks. Some practices also administer kennel cough (Bordetella) as a separate intranasal vaccine. Your puppy is not considered fully protected until approximately two weeks after their second injection.
Until that point, avoid letting them walk on public ground or come into contact with unvaccinated dogs. Gardens and private spaces where unvaccinated dogs have not been are generally safe.
Starting a Worming Programme
Puppies are frequently born with roundworms, passed from the mother in utero or through milk. Your vet will recommend worming at two to three weeks of age, then every two weeks until twelve weeks, then monthly until six months old. After that, quarterly treatment is standard for most adult dogs. Use a veterinary-grade wormer — many over-the-counter products sold in pet shops are significantly less effective.
Flea and Tick Prevention
Even if your puppy shows no signs of fleas, prevention is easier than treatment. Your vet will advise on appropriate products for your puppy's age and weight. Many spot-on treatments and oral preventatives are not suitable for puppies under eight weeks or under a certain weight, so always follow label guidance and seek professional advice.
Weeks Two and Three: Diet, Socialisation, and Dental Health
Feeding Frequency and Amounts
Puppies under twelve weeks need three to four meals per day. Their blood sugar and digestive systems are not yet mature enough for one or two larger meals. Use a complete puppy food appropriate for their size category — large breed puppies have different calcium and phosphorus requirements to small breeds and must not be fed standard puppy food, as this can contribute to skeletal problems during growth.
Weigh your puppy weekly and adjust portions according to the feeding guide on your chosen food. Puppies grow rapidly, and what was the right amount one week may be insufficient the next.
Beginning Teeth and Ear Care
Start handling your puppy's mouth, ears, and paws from the very first week. This is not about cleaning yet — it is about desensitisation. A puppy who is comfortable having their mouth touched will be far easier to brush as they grow. Introduce a soft finger brush around three to four weeks in, using veterinary toothpaste only. Never use human toothpaste, which contains xylitol, a compound that is toxic to dogs.
Week Four: Review, Microchipping, and Next Steps
Microchipping: Legal Requirement in England, Scotland, and Wales
Under UK law, all dogs must be microchipped and registered by the time they are eight weeks old. Most reputable breeders will have done this before handing over your puppy. If not, your vet can microchip during any routine appointment. Make sure your contact details are up to date on the relevant database — Petlog and Microchip Central are the most widely used in the UK.
Assess Socialisation Progress
By day 30, your puppy should have been exposed — in a safe and positive way — to a range of sounds, surfaces, people of different ages, and ideally other vaccinated dogs. If any of these areas feel behind, prioritise them in weeks five to twelve. The socialisation window closes around twelve to sixteen weeks, and what is missed during this period is difficult to compensate for later.
Plan Neutering
Neutering timing is a topic worth discussing with your vet early. Research published in recent years, particularly around larger breeds, suggests that early neutering before twelve months may increase the risk of certain joint conditions. Your vet can advise based on breed, sex, and individual factors. There is no single correct answer, but it is worth having the conversation before your puppy reaches sexual maturity.
A Quick Reference Checklist
- Book a vet appointment within 48 to 72 hours of arrival
- Continue existing diet for the first week, then transition gradually
- Start vaccination course at eight weeks if not already begun
- Begin worming protocol as directed by your vet
- Apply age-appropriate flea and tick prevention
- Feed three to four small meals per day
- Begin handling mouth, ears, and paws daily
- Confirm microchip registration details are correct
- Introduce socialisation experiences in a safe, controlled way
- Discuss neutering timing with your vet before six months
The first 30 days set the tone for everything that follows. Moving through this checklist methodically, without rushing, gives your puppy the strongest possible start.
