Set each horse's cycle first
A schedule is only a set of intervals written down, so start by fixing the right interval for each horse rather than the right date for the yard. Most horses in regular work need the farrier every five to eight weeks: fast-growing feet, hard road work and worn shoes pull a horse toward the short end, while a retired horse on soft ground who only needs a trim may sit comfortably at the long end — until his toes start to flare, which is the interval telling you it is wrong. Teeth run on a slower rhythm, a check about once a year for most adults, but young horses whose mouths are changing and old horses whose teeth are wearing out earn closer attention, and your dentist will tell you after the first visit which rhythm each horse belongs on. Write each horse's cycle on its record in plain sight — 'shoes, six weeks', 'teeth, yearly, autumn' — because the cycle, not your memory of the last date, is what generates every future appointment.
Book the next visit before this one ends
The single habit that separates yards where appointments never slip is booking the next visit while the farrier or dentist is still on the yard, tools in hand. They know their own diaries, they have just seen the horse's feet or mouth and can judge the interval honestly, and the appointment exists from that moment rather than depending on you remembering to phone in week five. If your farrier visits several horses, cluster them on the same day and the same cycle where their intervals allow — one visit, one diary entry, and the whole yard's feet marching together. Keep the booked dates where everyone sees them, on the yard board or the shared calendar, because a booking known to one person is a booking lost when that person is away on the day.
The per-horse record that makes the schedule trustworthy
Dates alone tell you when; a small record per horse tells you what, and the what is what makes future visits better. For each farrier visit note the date, the work done — trimmed, shod, any change of shoe or stud pattern — and anything the farrier remarked on: a foot growing unevenly, a shoe wearing thin on one side. For dental visits, record the work done and every observation: sharp points rasped, a tooth to watch, wolf teeth discussed. Two lines per visit is enough, but write them the same day, in the same place as the schedule itself. This running record is what turns a vague sense that a horse 'isn't quite right' into evidence — the shoeing that slipped to nine weeks, the tooth flagged at the last visit — and it is the first thing a vet, a buyer or a new farrier will ask to see.
When not to wait for the schedule
A schedule is for routine; it is not a reason to delay when a horse tells you something is wrong between visits. A cast shoe on a shod horse, a cracked or sprung shoe, sudden heat in a foot — these are farrier calls today, because a loose shoe tears hoof wall and a horse worked on three shoes strains the fourth leg. On the dental side, the signs are quieter but just as clear: quidding, where the horse drops wads of half-chewed hay, tilting the head to eat, resisting the bit in a new way, or losing condition despite good feed all mean the mouth needs looking at now, not at the autumn appointment. Keep your farrier's and dentist's numbers with the schedule so the call is easy to make. The schedule itself runs best as shared yard work: in KinsLe, Care Teams lets you set each horse's farrier and dental visits as recurring assigned duties, and each completed visit is marked with a timestamp — so the cycle, the booking and the record all live in one place the whole yard can see.
