New Puppy Checklist — Everything to Do in the First Month

Supplies to Have Before They Come Home

Crate sized for their adult size, with a divider panel to shrink the space while they're small. Puppy food — look for "growth" or "all life stages" on the label (AAFCO standard). Ask the breeder/shelter what they were already eating to avoid a sudden switch. Food and water bowls — stainless steel or ceramic is easier to keep clean than plastic. Collar with ID tag and a 6-foot leash — avoid retractable leashes for early leash training. Puppy-safe chew toys — teething starts around 3-4 months, and having appropriate outlets reduces furniture damage. Bed or crate mat — washable, since accidents happen. Enzymatic cleaner for potty accidents — regular cleaners don't fully remove the scent markers that draw puppies back to the same spot. Baby gates or an exercise pen to safely section off puppy-proofed areas. Puppy pads if you're in an apartment or expect to potty train indoors initially.

First Vet Visit & Health Setup

Schedule the first vet visit within the first week home, even if vaccines already started elsewhere. Bring any prior vet or vaccine records from the breeder, shelter, or rescue. Ask about deworming and a fecal parasite test — intestinal parasites are extremely common in puppies, even ones that look healthy. Start flea/tick and heartworm prevention as directed by your vet. Map out the core vaccine series — typically every 3-4 weeks from 6 to 16 weeks old. Book the booster appointments in advance so you don't lose track of the series. Ask your vet about spay/neuter timing — this varies more by breed size than people expect, especially for large breeds. Microchip your puppy — often done at the first vet visit or spay/neuter appointment.

Home Prep & First Month Routine

Puppy-proof cords, toxic plants, and small chewable objects at nose and mouth height. Secure trash cans and any cabinets with cleaning chemicals or medications. Set a consistent potty break schedule — after meals, naps, and play are the most predictable trigger points. Start positive socialization before 16 weeks — new people, sounds, surfaces, and healthy vaccinated dogs, in small manageable doses. Enroll in a puppy class if one is available near you — structured socialization plus a head start on basic training.

Frequently Asked Questions

What vaccines does a new puppy need first?

The core vaccine series (DHPP, covering distemper, hepatitis, parainfluenza, and parvovirus) typically starts around 6-8 weeks and repeats every 3-4 weeks until 16 weeks old. Rabies is usually given as a single dose around 12-16 weeks, depending on local law. Non-core vaccines like Bordetella or leptospirosis depend on lifestyle — ask your vet.

When should a puppy have their first vet visit?

Ideally within the first week of bringing them home, even if they've already had some vaccines from a breeder or shelter. This visit establishes a baseline health check, confirms the vaccine schedule, and screens for parasites — waiting is one of the most common new-owner mistakes.

How long is the puppy socialization window?

The primary socialization window closes around 16 weeks of age. Positive exposure to new people, sounds, surfaces, and other vaccinated, healthy dogs during this window has an outsized effect on adult temperament — it's a narrower window than most new owners expect.
