New Puppy Checklist: Everything You Need for the First Week Home

A puppy's first week home is mostly about rest, routine, and feeling safe in a new place.

The first week with a new puppy goes better when the boring work is done before pickup day. This checklist covers what to buy, how to set up your home, the veterinary visit that should happen in the first few days, and a simple daily rhythm for week one. It is organized in the order you will actually need things: before pickup, the first day, and the rest of the week.

Before pickup day: the supply list

Food — start with what the puppy already eats

Ask the breeder, shelter, or rescue exactly what food the puppy has been eating, and buy a bag of the same food. An abrupt food change is a common cause of an upset stomach in the first week. If you plan to switch foods, do it gradually over about a week, mixing increasing amounts of the new food into the old — the transition approach the American Kennel Club (AKC) recommends for puppies. You will also need food and water bowls (stainless steel or ceramic are easiest to keep clean) and a supply of small training treats.

A crate sized for now, not for someday

The AKC's sizing rule is simple: the crate should be big enough for the puppy to stand up, turn around, and lie down comfortably — and not much bigger, because puppies avoid soiling their sleeping area and a too-large crate gives them a bathroom corner. For a puppy who will grow, choose an adult-size crate with a divider panel and move the divider as the puppy grows. Add washable bedding you will not mind laundering often.

The rest of the essentials

Identification: tag plus microchip

An ID tag works the moment your puppy slips a collar, but tags get lost. The American Veterinary Medical Association (AVMA) recommends microchipping as permanent identification, with your contact details kept current in the chip registry — a chip only works if the registration is up to date. If your puppy is not already chipped, put it on the agenda for the first veterinary visit.

Before pickup day: puppy-proof one room

Start your puppy in one small, easy-clean area — usually a kitchen or laundry room — rather than the whole house. Get down to puppy height and remove or secure: electrical cords, cleaning chemicals, medications, small objects that fit in a mouth, and shoes you care about. Decide where the outdoor toilet spot will be; you will be visiting it many times a day, including at night.

Book the first veterinary visit before you bring the puppy home

New puppies should see a veterinarian within the first few days at home, even if the breeder or shelter provided initial care. Bring whatever health records you received. At that visit the veterinarian will examine the puppy, review vaccination and deworming status, and set the schedule for the rest of the puppy series.

Why the schedule matters: the American Animal Hospital Association (AAHA) vaccination guidelines are built around booster visits every few weeks through the first months of life, because the immunity puppies get from their mother fades at an unpredictable rate and young puppies need a series of vaccinations to build their own protection. Expect repeat visits roughly every three to four weeks until your puppy is about four months old, with exact timing set by your veterinarian for your puppy. This is also the visit to discuss parasite prevention, microchipping, spay/neuter timing, and whether pet insurance makes sense for your budget — a decision that is easiest before anything has been diagnosed.

Day one: keep it small and calm

The rest of week one: a simple rhythm

Puppies thrive on predictability. A workable first-week rhythm looks like this:

When to call the veterinarian during week one: not eating for more than a day, repeated vomiting or diarrhea, lethargy out of proportion to a big day, coughing, or anything that simply looks wrong to you. Young puppies can go downhill quickly, and veterinarians would always rather get an early call than a late one.

Paperwork to finish in week one

Week one is not about a trained puppy; it is about a puppy who eats, sleeps, toilets outside more often than inside, and learns that your home is predictable and safe. Get the rhythm right and the rest of puppyhood — crate training, biting, walking on leash, everything in our Puppy Care section — gets much easier.
