The new-pet checklist: first 30 days
The first month with a new puppy or kitten is chaos, and it's also when a handful of unglamorous tasks quietly determine the next 15 years of vet bills and lost-pet odds. Here's the whole month on one page, in order.
Days 1 to 3: the vet visit
Book the first exam before you bring your pet home if you can; within 72 hours regardless. Odds are nothing is wrong; book it anyway, because everything downstream depends on this visit:
- Most breeder and shelter health guarantees require an exam within a few days to stay valid.
- It establishes the baseline medical record: weight, heart, joints, parasites. A documented healthy start is worth real money later; it's the "before" picture if an insurer ever reviews the history.
- You'll leave with the vaccine schedule, deworming plan, and flea/tick/heartworm prevention, which means the rest of the month is already planned.
Bring every paper the breeder, shelter, or rescue gave you, plus a stool sample if you can manage it. Intestinal parasites are the most common finding in new puppies and kittens, and the test is cheap.
Days 1 to 7: the insurance window
This is the item people postpone, and it's the one with a real deadline. Pet insurance never covers pre-existing conditions, and "pre-existing" means anything that shows a symptom before your coverage's waiting periods clear. An eight-week-old puppy has no history; nothing is excluded. Every week you wait is another chance for an ear infection or a "let's monitor this" to get typed into the record and excluded for life.
The other reason to do it now is price: premiums are set by age at enrollment, and puppy and kitten rates are the cheapest your pet will ever see. Which policy is a separate research project we've already done; the short version is that for a new pet with a clean slate, an unlimited-payout policy like Trupanion's is the strongest version of the product, because nothing is pre-existing yet and every future condition is covered for life.
Days 7 to 30: the vaccine series and the socialization clock
Puppies and kittens need booster visits every 3 to 4 weeks until about 16 weeks old. Put every one in your calendar now; the series only protects when it's completed. Between visits, two clocks run at once:
- Socialization (puppies especially): the prime window closes around 14 to 16 weeks. Controlled exposure to people, sounds, surfaces, and vaccinated dogs now prevents the fear behaviors that are expensive and hard to fix at age two. Your vet can point you to a puppy class that requires proof of first vaccines.
- Pet-proofing: new pets eat socks, cords, lilies (genuinely lethal to cats), gorilla glue, and anything that smells like you. Obstruction surgery runs $3,000 to $7,000, and it's the signature claim of the under-one crowd. Crates and baby gates are cheaper.
This is also the month to ask about spay/neuter timing (it varies by breed and size now; there's no single right answer anymore) and to start touching paws, ears, and teeth daily so grooming and vet handling aren't a wrestling match for the next decade.
Before day 30: the boring paperwork
- City or county pet license, if yours requires one (most do, and the fine exceeds the fee).
- One folder (physical or a phone album) holding: adoption contract, vaccine records, chip number, insurance policy, and every invoice. Future-you files claims out of this folder.
- ID tag on the collar with your cell number. The chip is the backup; the tag is what gets a neighbor to text you in ten minutes.
- Pick your permanent vet if the first visit was a stopgap, and have any prior records transferred.
- Save your ER's address in your phone: the nearest 24-hour hospital, before you need it. Our emergency guide covers the rest.
Everything on this list can slip a week except the insurance window; that one's priced by the calendar and closed by the first symptom. Two minutes gets the number for your actual puppy or kitten.

Week one: vet exam, insurance, chip registration. Weeks two through four: boosters on schedule, socialization on purpose, house made swallow-proof. Before day 30: license, records folder, ID tag, permanent vet, ER address saved. It reads like a lot, but most of it is a single vet visit plus some browser tabs.
