The short answer for a Clydesdale emergency plan
A good emergency contact plan for a Clydesdale answers one question fast: when something goes wrong with a horse this big, who can actually help, and how do they reach each other? List yourself first, then a backup person who knows the horse and can make decisions if you are unreachable, followed by your regular veterinarian, the nearest after-hours equine hospital, a farrier experienced with draft feet, and a hauler with a trailer tall and sturdy enough for a Clydesdale. Beside every name, write a phone number, the best time or way to reach that person, and what you expect them to do.
Identification details a stranger would need
Someone covering for you may know horses but not this horse, so the plan should identify him beyond doubt. Include his registered and barn names, age, sex, colour, blaze and leg markings, and recent photos taken from both sides, the front, and close up on the feathering around his lower legs. Note his microchip number if he has one, where he is stabled, which stall or field he uses, and any halter or handling quirk a newcomer should know, such as needing a calm, unhurried approach at the wash rack. A weight estimate and his usual vital-sign ranges, if your veterinarian has recorded them, help a covering vet judge how he compares with his normal self.
Care facts that travel with the contacts
Contacts alone are not enough if nobody knows his routine. Add what he eats, how much hay and feed he gets at each meal, where the feed is stored, and which treats or feeds he must avoid. Write down supplements he receives, ongoing care notes from recent vet or farrier visits, and the date his hooves were last trimmed or shod, because draft feet carrying that much weight should not silently run overdue. Include his turnout companions, the horses he should not share a fence line with, and simple handling notes like how he loads, ties, and stands for grooming.
Decisions to settle before anything happens
The hardest calls are easier made in advance. State who may authorise emergency veterinary treatment in your absence, whether he is insured and where those details are kept, and which hospital you prefer if he needs transporting. Name the hauler again here, and confirm the trailer plan honestly: a standard trailer that suits a riding horse may be far too small for a Clydesdale, so the plan should say exactly whose rig fits him and where it is kept. Note the barn owner's or yard manager's number too, since they control gate access, water, and power after hours.
Keeping the Clydesdale plan current
A plan only works if the numbers still ring. Check it whenever a vet, farrier, hauler, or barn changes, after any stay away from home, and whenever his feed or care routine shifts. Leave printed copies where a helper would actually look: with his feed instructions, in the tack room, and with your backup person, not buried in a truck glovebox. Walk one helper through the plan in person so the first reading is not during a crisis. Storing the finished plan in KinsLe as part of his Pet Passport keeps those contacts, photos, and care notes gathered in one portable packet that a helper, vet, or hauler can be handed in seconds.
