How to keep track of pet vaccine due dates

Vaccine due dates are easy to lose — not because you're careless, but because there's no obvious place they're supposed to live. A date on a paper certificate. A note in a vet portal you rarely log into. A reminder someone set on a phone that got replaced two years ago. This guide covers a simple system for keeping due dates findable, attached to the records that back them up, and on your schedule — not someone else's.

Your records, your reminders

Most vet clinics send appointment reminders — postcards, emails, automated texts nudging you to book. Those are useful, but they're built around the clinic's schedule, not yours. They tell you when the practice wants to see your pet, not necessarily what's actually due or when it matters for the other things in your life: a boarding trip, a daycare enrollment, a move to a new city with a new vet.

An owner-first reminder system starts from your records, not from a clinic's booking calendar. When you know what's in your pet's history and when things are due, you're in a position to act — not just to respond.

Why vaccine dates are easy to lose

The date a vaccine was given usually lives in one place: the certificate your vet hands you or emails after the appointment. That certificate is easy to misplace, easy to leave in a car, and easy to forget you ever had. The due date for the next one is often printed on the same page — which means when the certificate disappears, the due date disappears with it.

Vet portals help, but only if you remember to log in, only if your vet uses one, and only if you stay with the same practice. When you switch vets, travel, or board your dog or cat somewhere new, the history you need is wherever the last vet kept it — not with you.

Keep the vaccine record and due date together

A due date stored separately from the record that explains it is easy to question. When the only thing you have is a calendar reminder that says "Bordetella due," you have no way to verify it without digging through paperwork. When the due date lives inside the vaccination record — alongside the date given, the vaccine brand, and the certificate — you can see the full picture at a glance.

Treat the record as the source of truth. The reminder is just a way to surface it at the right time.

Save proof, not just the date

Daycares, boarding facilities, catteries, groomers, and some dog parks ask to see the actual certificate, not just your word that the vaccine was given. A date in your phone's notes app isn't enough. The certificate — the document your vet issues — is what they need.

Whenever you receive a vaccine certificate, attach it to the vaccination record before you forget. A PDF, a photo, a scan — any format works as long as it's stored close to the record it belongs to, and you can pull it up on your phone when someone asks for it. In Willow, you can scan a certificate straight into the record it belongs to, so the proof and the due date stay together from the start.

Set reminders before the date matters

Vaccine reminders are most useful when they arrive early enough to act on, not the week a vaccine expires. If your dog's Bordetella is due in three weeks and you're boarding her in four, you need to know now — not the day before drop-off. The same holds for a cat: if your cat's FVRCP or rabies booster is coming up before a cattery stay, early notice is what turns a scramble into a non-event.

A reminder set 30 days before a due date gives you time to book the appointment, get the vaccine, receive the updated certificate, and have it ready before you need it. Your veterinarian can advise on the specific timing for each vaccine.

Review upcoming care monthly

Reminders catch individual due dates. A monthly review catches patterns. Once a month, scan your pet's upcoming care for anything in the next 60 days: vaccine renewals, wellness visits, medication refills, dental cleanings. Five minutes of looking ahead is usually enough to avoid a last-minute scramble.

If you have more than one pet, do this review for each of them. Dates that seem far off have a way of arriving at the same time.

Keep notes for each pet in multi-pet households

In a household with more than one dog or cat, it's easy for records and due dates to blur together — especially when pets are on similar schedules or see the same vet. Keep each pet's records completely separate from the beginning. A due date that looks familiar might belong to a different animal.

Share proof when daycare, boarding, or travel requires it

Vaccine records exist to share. When a facility asks for proof, the process should take seconds — not ten minutes of searching. If your records are organized with documents attached to the right entries, sharing is straightforward: you open the record, pull up the certificate, and hand it over.

If you use daycare or boarding regularly, here's what facilities typically ask for and how to have it ready. For cats specifically, here's the cat vaccine schedule and what catteries look for.

How Willow helps

Willow is a pet health organizer built for owners, not clinics. It uses the dates you save — not a clinic's booking calendar — to keep vaccine reminders on your schedule. Records, due dates, certificates, and reminders live in one place, organized by pet, so you know what's coming and have the proof ready when someone asks.
