How long does your vet keep your pet's records?

You phone the clinic you left four years ago, asking for the bloodwork from the winter your dog was ill. The receptionist checks, pauses, and tells you the file has been purged. Nothing went wrong and nobody made a mistake. The record simply reached the end of the period it had to exist for.

There is no single answer to how long that is. It is set by the regulator where the practice sits, the periods are shorter than owners expect, and the clock runs from your last visit rather than from the day the test was done. Ontario requires at least five years. Virginia requires three.

How long is a clinic actually required to keep them?

Long enough for continuity of care, and then the obligation ends.

The College of Veterinarians of Ontario states in its guide to the medical records standard that records “must be retained for a period of at least five years after the date of the last entry in the record or until two years after the member ceases to practice veterinary medicine, whichever occurs first.” Virginia’s Board of Veterinary Medicine is shorter and blunter: under 18VAC150-20-195, patient records “including radiographs or digital images, shall be kept for a period of three years following the last office visit or discharge of such animal from a veterinary establishment.”

Two neighbours in the same profession, two years apart. That gap is the reason to look yours up rather than borrow a number from an article.

What is the minimum in each province and state?

Somewhere between three and seven years after your last visit, in every province and state below, and the United Kingdom sets no fixed period at all. Each row is the regulator’s own minimum, read from its bylaw, standard or regulation on 27 September 2026 and linked so you can check it. A clinic may keep records for longer than this; it may not keep them for less.

“Start not stated” means the rule gives a period without saying when it begins. The longest minimum, seven years, applies in British Columbia, Nova Scotia and Michigan; most US states in the table sit at three. In the UK the RCVS asks practices to keep clinical records “for as long as is necessary”, with legal duties such as the veterinary medicines rules deciding what that means for a given file.

Which date does the clock actually run from?

The last time anything was written down, which is a friendlier rule than it sounds.

A pet you still take to the same practice has a record that keeps renewing itself, because every visit resets the count. The file at risk is the one nobody has added to: the practice you left, the specialist you saw once, the emergency hospital from the bad night three years ago. Those are the records aging quietly, and they are usually the ones holding the imaging.

So the question worth asking is how long ago that clinic last touched the file the X-ray sits in. An insurer can ask for exactly those older months, which is why a pet insurance claim usually starts from the whole file.

What happens to the imaging?

In Ontario it travels with the record rather than keeping its own calendar. CVO’s rule is that radiographs are retained for as long as the patient record is retained, “regardless of the date the radiograph was taken,” and that once a record can be purged, the radiographs associated with it can be purged too. An image from eight years ago is safe while the file is alive and gone the moment it is not.

Virginia handles it by naming images in the retention rule itself, and adds a detail worth knowing if you ever collect the originals: where an original radiograph or digital image is transferred elsewhere or released to the owner, the establishment has to keep a record of that transfer with the patient’s file.

What if the practice closes?

You get roughly two more years, and no reminder.

CVO requires a veterinarian who closes a facility to arrange for records to be stored for up to two years after the closure, kept secure and accessible to the client on request, and says both clients and the College should be told how to access them. That is a real protection, and it is also a short window that opens at the worst possible moment, when the practice you would have phoned no longer answers.

A closing clinic is the one event that should move “request a copy” from a someday task to a this-week task.

Can you ask a clinic to delete the record?

No. CVO answers it as its own question and the answer is one word long: a veterinarian is required to retain the complete record for the full period even if the client asks for it to be purged and even if the client consents.

It cuts the other way too, and more usefully. The information in the record belongs to the client, who has the right to access its content, a request can be made by phone rather than in writing, a complete copy should be transferred within two business days, and a practice may not hold the release back over money you owe. The original stays put for the full period. A copy of it is yours whenever you ask.

What is worth copying, and when?

Three moments, none of which arrive with a warning: when you leave a practice, when a practice closes, and when a course of treatment ends and the file goes quiet.

What to ask for is the part a summary drops. The imaging rather than the report of it. Lab results with their dates, so the series is preserved and not just the latest value. The vaccination history, which is the document everyone else will ask you for. Anything from before you owned the pet, which may be legally unavailable and will not announce its absence. The mechanics of the request, including the fee rules and what a transfer covers, are set out in how to switch vets and transfer your pet’s records, and asking for the complete file is covered in getting a copy of your pet’s medical records. Keeping what comes back in order is the subject of the guide to pet health records. Read the copy when it arrives. If a visit sits under the wrong date or a note belongs to another animal, correcting an error in your pet’s vet records explains how to ask the clinic to review it.

One document deserves separate treatment, because a copy of it is the thing boarding kennels, groomers and landlords actually ask for: the rabies certificate, which has its own route to a replacement.

Where Dana fits

Retention periods are a clinic’s obligation and a household’s blind spot. The practice is keeping the original for its own regulator, on a clock that started at a visit you have probably forgotten, and the day it expires is invisible from your side.

Dana holds the copy that has no expiry date. The health record keeps vaccine dates, the weight series, the medication schedule and the microchip number in one place, with each entry carrying who logged it and when. The Records Vault, part of Dana Pro, stores the documents themselves, the PDFs and the photographed certificates, and shares them through a code-gated link that expires on its own. A file you hold is a file that outlives the practice that made it.
