A Mustang's health record starts with honesty about its paper trail, because many of these horses arrive with adoption documents, a freeze brand, and an estimated age rather than a breeder's file. Head the record with the horse's name, brand description in words, colour and markings, estimated age and who estimated it, and origin details if they are documented. From there, keep vaccinations, Coggins results, dental findings, hoof care, deworming as your vet advises, and illness or injury notes in one dated timeline that never pretends estimates are facts.
Recording identity and age when both are partly estimated
Recording a Mustang's identity means describing the freeze brand character by character if one is present, plus scars, whorls, and any old injury marks, because a brand that is misread in the file will not match the horse at a border or a show ground. For age, write the dental estimate, the date it was made, and the vet who made it, and update the working age only when a later dental exam revises it. Note handling level beside identity — halter-broken on arrival, gentled over months, now riding — because a vet planning sedation or a first float needs that context before the horse is in front of them.
The first vet visits: building a baseline from scratch
A Mustang's early vet visits create the baseline every later entry depends on. Log the first full exam in detail: teeth state, old splints or scars, body condition after gather or rescue, feet condition, and any vaccine history the seller or agency could actually confirm versus what was started fresh with you. If a vaccine series was begun because prior cover was unknown, write that reason down. Mustangs gathered from range conditions may carry gaps that are nobody's fault, but an unexplained gap in the file looks like neglect later, while an explained one reads as careful ownership.
Hoof, dental, and training-linked health entries
Hoof and dental entries carry extra weight in a Mustang file because range feet and unexamined mouths are common starting points. Record the trim cycle, any transition from overgrown or cracked feet, and shoeing decisions as training progresses from groundwork to riding. Enter float findings plainly, including hooks or ramps that affected eating. Beside those entries, note training milestones and setbacks — first trailer load, first farrier visit without incident, a spook-related injury. A Mustang's health and training histories genuinely explain each other, and keeping them apart hides why a horse regressed or improved.
When to call the vet, and keeping the file transferable
A Mustang record should prompt a vet call for colic signs, a non-weight-bearing lameness, a wound near a joint, rapid weight loss, choke, or a horse who stops drinking after a move or gather-related stress, with your dated notes on appetite, droppings, and handling state ready to share. Because Mustangs are rehomed more often than many breeds, write every entry so a stranger can follow it without you translating. KinsLe's Pet Passport gathers a Mustang's adoption details, vaccine timeline, and dental history into one packet that moves with the horse if ownership changes.
