Quarantine is for the healthy-looking new arrival, not just the horse who steps off the lorry coughing. Many yard infections are incubating silently during their first days in a new home, so plan on two to three weeks of separation — many yards use a full twenty-one days, and your vet or yard policy may set a longer period after illness at the horse's previous home. The clock only counts if the separation is real; a horse who can touch noses over a fence is not in quarantine, however far apart the stables are.
Setting Up Real Separation
House the new horse where it can see and hear other horses — isolation within sight settles a horse far better than solitary confinement — but cannot share airspace at close range, water, feed, or grazing contact with them. Give it dedicated buckets, feed bowls, headcollar, grooming kit, and mucking-out tools that stay in its area for the whole period, marked if necessary so nobody borrows them back to the main yard. Keep its manure separate too, and avoid turning the newcomer out on pasture the resident herd will graze immediately afterwards.
Work the yard in the right order: feed, muck out, and handle all resident horses first, the quarantined horse last, every day. Wash hands after handling it, clean or change boots before walking back through the main yard, and do not share rugs, numnahs, or tack during quarantine. Anyone else handling the horse — farrier, instructor, a friend helping out — follows the same order and the same rules, or the system leaks.
The Daily Checks That Make Quarantine Worth Doing
Check the horse twice a day and write down what you find: temperature taken at the same times daily, appetite and how much hay and water it is getting through, droppings, breathing at rest, and any cough, snotty nose, swollen glands, skin lumps, or diarrhoea. A single raised temperature, a horse off its feed, or a new cough is a phone call to your vet that day, not a wait-and-see — and the quarantine extends until your vet advises otherwise, restarting the clock if a contagious problem is confirmed. Ask the seller or previous yard, before arrival, for vaccination and worming history and any recent illness on their yard, and arrange worming and vaccination catch-up with your vet during the quarantine window rather than after turnout, so the horse joins the herd already aligned with its programme. This is general guidance, not a diagnosis: your vet sets the protocol for your yard's situation.
Joining the Herd
Introduce gradually once quarantine ends cleanly: turnout alongside, then with one steady resident companion, before full herd turnout, watching the first days for injuries and bullying at hay and water. Keep the daily notes; the pattern of temperatures across three weeks is exactly what settles arguments later about when a sign began.
Storing the arrival papers, vaccination and worming history, and those daily temperature and appetite notes in KinsLe's Pet Passport means the whole quarantine travels with the horse's record, ready for your vet, the yard manager, or a future move.
