Most owners do not decide to keep poor records; the records simply scatter. The passport lives in the car, the dentist's receipt is in a coat pocket, the vaccination date is in the vet's computer and the farrier's card is pinned to a board that gets cleared every spring. One file per horse, kept deliberately, ends the scatter — and its value shows on the worst days, not the ordinary ones.
Identity and ownership documents
The core of the file is the passport, the document that identifies the horse and records ownership. With it belong the bill of sale from when you bought the horse, any registration or breed society certificates, and the microchip paperwork. If the horse is on loan, or you loan yours out, the signed loan agreement belongs here too, because it is the document that proves who is responsible for the horse while it lives away from its owner. Insurance documents sit in this section as well — the policy itself and any correspondence about exclusions, which are the first thing anyone asks about when a claim starts.
Health records that build a history
Vaccination records are the minimum, and in many passports they are stamped directly into the book. Beyond those, keep a note of every vet visit: what the horse was seen for, what was found, what was done, and what you were told to watch for. Dental records matter more than owners expect — the state of an older horse's teeth explains weight loss that feed changes cannot. Farrier records showing shoeing dates, changes of shoe type and any remedial work build a picture of the feet over time, and worming dates and worm count results complete the routine picture. None of these need specialist forms; dated notes in one place beat perfect paperwork in five places.
Everyday management paperwork
The third layer is the running of the horse's life: a livery contract if the horse is kept at a yard, feed and supplement details written down rather than held in one person's head, saddle-fitting and physio notes, and competition or society memberships if the horse competes. This is the section a stand-in carer reads when you are away, and the section a buyer reads when you sell, so write it for a stranger, not for yourself.
Keeping the file alive
A file works if adding to it is effortless: one folder or wallet per horse, new paperwork dropped in as it arrives, and a quick tidy once a season to throw out superseded insurance schedules and old entry forms. The original passport should live somewhere dry and findable, and the working details should be reachable on an ordinary yard day. That is the habit KinsLe's Pet Passport is designed around — the horse's records gathered into one portable packet, ready for a vet visit, a yard move or a sale, instead of spread across the car, the coat pocket and the feed room.
