Racing identity and the history you inherit
A Thoroughbred record starts with identity that can be verified: registered name, stable name if different, age, sex, colour, and photographs of markings, whorls, and any scars. Record lip tattoo or microchip details where present, and file sale, auction, or rehoming paperwork behind the identity page with the seller or rehoming organisation contact described in plain terms. Add his racing history as it was given to you — starts and level in general terms, his preferred distance or surface if known, and his reason for leaving racing. Most important, write down disclosed injuries, surgeries, or long layoffs exactly in substance, and mark clearly what is documented on paper and what was only told to you. A Thoroughbred's next vet, trainer, and owner all deserve to know which is which.
Feed transition and condition tracking
A Thoroughbred feed record should document the step down from racing rations: what he arrived eating, how concentrates changed, forage type and access, and how his weight, coat, energy, and droppings responded week by week. Thoroughbreds commonly arrive lean and fit rather than fleshed, so a regular weight-tape entry paired with honest condition notes and dated side photos gives you evidence of progress that daily familiarity hides. Note ulcer-type signs only as observations — appetite dips, girthiness, a dull coat, behaviour at feeding — and raise recurring patterns with your vet, who can decide what investigation is appropriate. Log turnout introduction in the same section, because a horse new to field life often eats, moves, and stresses differently all at once, and the combined record is what makes those weeks interpretable later.
Retraining and behaviour notes
A Thoroughbred retraining record should date the milestones of his second education: settling into a routine, first rides in an arena, canter work in both directions in general terms, jumping introduction if relevant, hacking, traffic, and loading practice. Note his racing-installed responses honestly — leaning on the bit, hurrying when company passes, standing at a mounting block — and which exercises are changing them. Log who rode and what was asked, because an ex-racehorse ridden by several people needs consistency that only a shared written record creates. Behaviour notes belong here too: stable habits, weaving or box walking if present, separation stress, and how he copes with clippers, hosing, and the farrier.
Farrier, dental, and veterinary spine
A Thoroughbred health record should keep farrier, dental, and veterinary entries in one chronological run. Log shoeing with notes on hoof quality — racing feet moving to riding work often change — and any farrier comment on balance or cracking. Dental entries should note eating changes or bit behaviour around each check. Veterinary entries carry reason, general findings, follow-up, and review timing, and old racing injuries deserve a standing summary page that new entries can reference, so a vet meeting him fresh understands his baseline before an examination begins. Record dated observations after workload steps: a leg that fills after jumping, stiffness after a day off, or a cough in a new stable.
One continuous story for a much-moved breed
A Thoroughbred file should assume he will be seen by people who never met his racing self: order it identity and racing history, feed transition, retraining, then health. Back the papers up with phone photos, and review the whole file before a yard move, a new discipline, or a sale or loan, completing any seller details while you can still ask. Honesty is the file's value — a disclosed old injury with a clear management history serves a Thoroughbred better than a suspicious blank. Binding racing identity, feeding, and retraining notes into KinsLe Pet Passport keeps a Thoroughbred's full history in one packet that travels with him wherever his second career leads.
