Why Paper Vaccination Records Keep Letting Pet Owners Down

The card is somewhere. James is fairly sure of that. It’s either in the kitchen drawer — the one with the batteries and expired coupons — or it was left at the old flat, or possibly handed to the vet at the last appointment and never returned. His cat, Omelette, needs to board for ten days while he travels for work. The cattery needs proof of vaccinations. James has three days to find a card he last saw eighteen months ago.

If this sounds familiar, you’re in good company. Across the world, this scene plays out thousands of times a day. A pet needs to travel, board, or see a new vet, and the paper record that’s supposed to travel with them is missing, damaged, incomplete, or locked inside a practice’s software system on the other side of the city.

Paper vaccination records were a reasonable solution for a different era. They’re not keeping up with the way people and pets actually move through the world in 2026.

What Paper Records Were Designed For

The logic of the paper vet card made sense when most people lived in the same place for decades, saw the same vet their whole lives, and rarely crossed borders with their pets. Under those conditions, a physical card in a drawer — topped up at each annual check-up — covered most situations.

But modern pet ownership looks nothing like this. People move cities and countries. They use multiple vets — a regular practice, an emergency clinic, a specialist. They board pets, use dog walkers, attend training classes, enter shows, and cross borders. Each of these touchpoints may require proof of the same records, and each is a new opportunity for the paper trail to break down.

The Four Ways Paper Records Fail

1. They get lost. This is the obvious one, and it’s more common than anyone likes to admit. A survey of pet owners in the UK found that nearly a third couldn’t locate their pet’s vaccination records without calling their vet. That’s a third of owners effectively flying blind if their pet needs emergency care away from their regular practice.

2. They’re incomplete. Most paper cards only capture vaccinations. They don’t include medication history, allergy flags, surgical notes, parasite treatments, dietary requirements, or the dozens of other details that matter enormously in an emergency or at a new clinic. When the card is all you have, that’s all you can share.

3. They can’t be verified. A paper record is a stamp and a signature. It can be forged, and anyone who has worked in professional pet care knows this happens. For international travel in particular — where vaccination requirements can mean the difference between your pet entering a country or spending weeks in quarantine — an unverifiable paper certificate is an increasing liability.

4. They belong to the wrong person. This is the subtlest failure, but arguably the most significant. When your pet’s health history lives inside a veterinary practice’s system, it belongs to that practice. You have access to it by courtesy — as a printout, a verbal summary, or an email if you ask nicely. But if you move, if the practice closes, if there’s a dispute, or simply if you’re abroad at 11pm with a sick animal, those records may as well not exist.

What Happens at the New Clinic

Every pet professional has a version of the same story. A new patient comes in. The owner fills in a form. The form asks about vaccination history, current medications, known allergies. The owner guesses, approximates, or leaves fields blank. The vet works with incomplete information.

In most cases, this is fine. In some cases, it isn’t. An undisclosed drug sensitivity, a missed booster that everyone assumed the previous clinic had administered, an allergy written on a record no one thought to transfer — these gaps have consequences.

And the cost isn’t only medical. The time spent at intake, the repeat diagnostics run to compensate for missing history, the re-vaccinations administered because records can’t be confirmed — these add up. For pet owners already navigating the cost of care, incomplete records are an invisible tax.

The Digital Alternative

A digital pet health record doesn’t just replicate a paper card on a screen. Done properly, it changes the fundamental structure of who owns the information and how it travels.

When records are stored in a portable, owner-controlled digital format:

• The history is complete — not just vaccinations, but medications, conditions, treatments, and notes
• It moves with the pet, not with the practice
• It can be shared instantly with any vet, boarding facility, or border control, anywhere in the world
• It can be cryptographically verified — meaning a boarding kennel or customs officer can confirm the record is genuine without calling anyone
• The owner is always in control of who sees what

This is the model Petso is built on. Your pet’s health passport — including vaccination history, medical records, and registration details — lives with you and travels wherever you and your pet go. You share it on your terms.

Making the Switch

If you’re still relying on a paper card, the first step is simpler than it sounds: ask your vet for a copy of your pet’s complete record at your next appointment. Most practices can export this or provide a printed summary. From there, digitising it — and keeping it updated — means you’re never in James’s position again.

Omelette, for the record, was allowed to board. James found the card in the kitchen drawer, behind the batteries. But he spent two days looking, made three phone calls to the vet’s admin line, and swore — not for the first time — that there had to be a better way.

There is.
