Why Every Pet Needs a Health Record (And What to Track)

AIPet Team · July 26, 2026 · 7 min read

Quick test: without checking anything, can you say when your pet's rabies vaccine expires, what they weighed six months ago, and which month you started their current flea preventive? Most owners cannot, and it is not a character flaw. Pet health information gets scattered across clinic portals, shoebox receipts, and half-remembered phone calls, right up until the moment you need all of it at once.

A pet health record fixes that. It does not need to be fancy — a single page, kept current, will do — and it pays for itself the first time you use it. This guide covers why it matters, the accurate core vaccine timelines for dogs and cats, what else is worth tracking, and a prep checklist that makes every vet visit more productive. (A record supports your veterinarian's care; it never replaces it.)

Why a Health Record Matters

• The 2 a.m. emergency. An emergency vet who has never met your pet will ask about vaccines, medications, allergies, and prior conditions while you are at your most stressed. Handing over one page answers everything and can genuinely change treatment decisions, for example whether a medication interacts with something your pet already takes.
• Boarding, grooming, daycare, and travel. All of them require proof of vaccination, and rabies certificates are legal documents in most of the US and Europe. Scrambling for records the day before a trip is a tradition worth breaking.
• Switching or seeing multiple vets. Clinics can transfer records, but transfers are slow and often incomplete. Your copy is the backup that travels with the pet.
• Trends no one visit can see. A vet sees your pet for twenty minutes a year. You see them every day. Weight creeping up 8 percent, drinking gradually increasing, episodes of limping that cluster after long walks — patterns like these live in your notes, and they are frequently the earliest signal of thyroid disease, diabetes, kidney trouble, or arthritis.
• Multi-caregiver households. A shared record is how you discover the dog has been getting two dinners a night since March.

Dog Vaccines: The Core Timeline

The schedule below reflects the current American Animal Hospital Association (AAHA) canine guidelines. Core vaccines are recommended for essentially all dogs; your vet may adjust timing for your region and your dog's history.

Puppy series

• 6–8 weeks: first DAP dose (distemper, adenovirus, parvovirus — often listed as DHPP when parainfluenza is included).
• Every 2–4 weeks after: repeat DAP until at least 16 weeks of age. The final dose at or after 16 weeks is critical, because maternal antibodies can block earlier doses. Some high-risk breeds, such as Rottweilers and Dobermans, get an extra dose at 18–20 weeks.
• 12 weeks and up: leptospirosis, two doses given 2–4 weeks apart. Under the updated AAHA guidance, lepto is now recommended as core for virtually all dogs, not just rural ones — the bacteria spreads through wildlife urine in suburbs and cities too.
• 12–16 weeks: rabies, a single dose, with exact timing set by state or local law.

Adult boosters

• DAP: booster within 12 months of the final puppy dose (many vets now give it as early as 6 months to close the immunity gap), then every 3 years.
• Rabies: booster 1 year after the first dose, then every 1 or 3 years depending on the product label and local law. Record the certificate number and expiration date.
• Leptospirosis: annual booster.
• Lifestyle vaccines: Bordetella (kennel cough), canine influenza, and Lyme are given based on risk. If your dog boards or attends daycare, Bordetella will almost certainly be required — note the date, because facilities check it.

Cat Vaccines: The Core Timeline

This follows the AAHA/AAFP feline vaccination guidelines. Indoor-only status matters less than many owners assume, especially for kittens.

Kitten series

• 6–8 weeks: first FVRCP dose (feline viral rhinotracheitis/herpesvirus, calicivirus, panleukopenia).
• Every 3–4 weeks after: repeat FVRCP until 16–20 weeks of age. As with puppies, the dose at or after 16 weeks is the one that matters most.
• 8 weeks and up: feline leukemia (FeLV), two doses 3–4 weeks apart. FeLV is considered core for all kittens under 1 year old, including indoor kittens.
• 12–16 weeks: rabies, single dose, per label and local law.

Adult boosters

• FVRCP: booster at 6 months to 1 year after the kitten series, then every 3 years.
• Rabies: every 1 or 3 years depending on the vaccine used and local law.
• FeLV: after the first year, annual boosters only for cats with ongoing risk, such as outdoor access or a housemate of unknown FeLV status.

Beyond Vaccines: What Else to Track

Weight and body condition

Weigh your pet monthly on the same scale — for small pets, weigh yourself holding them, then subtract. Log the number and a quick body condition score from 1 to 9, where 4–5 is ideal (ribs easy to feel but not see, visible waist from above). Flag any change of 10 percent or more that you did not cause deliberately; unexplained loss in particular deserves a vet call, not a wait-and-see. Age changes the stakes: senior pets should see the vet twice a year, and "senior" arrives earlier for big dogs than small ones. Our free pet age calculator shows where your pet actually is in life-stage terms.

Symptom log

When something seems off, write down the date, what you observed, how long it lasted, and what preceded it. Better yet, take a video. Limping, coughing, head tilts, and seizure-like episodes are notoriously absent in the exam room, and thirty seconds of phone footage is worth more to your vet than five minutes of description. Note appetite, water intake, energy, and stool alongside — those four cover most of what a vet will ask.

Medications and preventives

Log every medication with dose, start and stop dates, and any reaction. Give heartworm and flea/tick preventives their own monthly tick-box row, because "did I give it this month?" is the single most commonly forgotten item in pet care. Anchor it to the first of the month and the question disappears.

Identity and emergency information

Record the microchip number, the registry it is enrolled with, and the phone number on file — then check yearly that the contact details are current, since an unregistered or outdated chip is nearly useless. Keep several recent, clear photos of your pet from different angles in the record too. It feels like a formality until the day a gate is left open, at which point having a good photo ready means you can generate a lost pet poster in minutes instead of panicking through your camera roll. The same photos double as proof of ownership. If you have done a DNA test — see our guide to finding out your dog's breed — file the health-screening results here as well, so any vet can see inherited risks at a glance.

Before Every Vet Visit: The 10-Minute Prep

1. Update the weight entry that morning if you can.
2. List anything that changed since the last visit: food, behavior, appetite, water, bathroom habits.
3. Write down your top three questions — exam rooms have a way of erasing memory.
4. Queue up any symptom videos on your phone.
5. Bring the medication list with exact doses, including supplements and preventives.
6. Note the food brand and daily amount; "a scoop of the orange bag" is not data.
7. For stomach issues, bring a fresh stool sample; call ahead to ask if one is needed.
8. Bring vaccine certificates if seeing a new clinic.
9. Confirm insurance or payment details before, not during, checkout.
10. Arrive ten minutes early so your pet can decompress before the exam.

A Simple Printable Record Card

Copy this structure onto one page, or into a note on your phone — ideally both, since paper works in a power outage and the phone is always with you:

• Basics: name, species, breed or mix, date of birth (or best estimate), sex, color and markings.
• Identity: microchip number, registry name and phone, license or passport number where applicable.
• Vaccines: one line each — vaccine, date given, date due.
• Medications and preventives: name, dose, schedule, start date.
• Allergies and reactions: drugs, foods, vaccine reactions.
• Weight log: date and weight, one line per month.
• Contacts: regular vet, nearest 24-hour emergency clinic, poison control hotline, backup caregiver.

Make It a Habit That Sticks

Set a fifteen-minute "pet admin" appointment on the first of every month: give the preventive, do the weigh-in, snap a quick photo on the scale, and update the record. That is the entire system. As a bonus, twelve months of scale-day photos make a surprisingly moving year-in-review — aipet.video can turn those photos into a short AI-generated film of your pet's year, and your first three videos are free.

A health record is one page of quiet effort that turns you into the owner every vet hopes walks through the door: the one with the dates, the doses, and the video. Your pet cannot tell anyone their history. This is how you do it for them.
