New Pet Owner Checklist: The Health Records You Need From Day One

6 min read  ·  Updated June 2026

The first few weeks with a new pet are the easiest time to build a record-keeping habit, because there's nothing to retroactively organize yet — you're just capturing things as they happen. Wait six months and you're reconstructing a vaccination history from memory instead.

Day one: the basics

The first vet visit: what to walk away with

Your first appointment usually covers an initial health check and the start of a vaccination series. Make sure you leave with — or immediately write down — the exact vaccines given, the date, and most importantly, the date the next one is due. Puppy and kitten vaccine series happen on a tight schedule, and missing a booster window can mean restarting part of the series.

The mistake most new owners make: assuming the vet's office will remind you. Some do, many don't reliably, and a missed reminder becomes your problem, not theirs.

What to log from week one onward

  1. Every vaccine — what, when, next due date
  2. Deworming and parasite prevention — start date and ongoing schedule
  3. Spay/neuter — date, if and when it happens
  4. Any reactions or sensitivities — to food, medication, or vaccines
  5. Growth and weight — useful for puppies and kittens especially, since rapid change is normal but worth tracking

Set the system up before you need it

The easiest moment to set up a tracking system is before you have six months of scattered paperwork to retroactively enter. Even just logging the first vet visit the same day you get home means everything after that builds on a real foundation instead of a gap you have to fill in later from memory.

Start your pet's record on day one

Set up your new pet's profile in PetFolio Health before the first vet visit, and every vaccine, weight check, and milestone has somewhere to go from the start.

What to expect over the first year

Most puppies and kittens go through a vaccine series every 3-4 weeks for the first few months, followed by a spay/neuter conversation around 5-6 months for many breeds, and a transition to adult food and an annual visit cadence around the one-year mark. Knowing this rhythm in advance makes the appointments feel like a plan rather than a surprise each time.
