Holiday cover for a Mustang is really a document about trust. A Mustang, particularly one gathered from the range or adopted with limited handling, may be perfectly settled with his owner yet wary, quick and strong with a stranger, so instructions that work for a domestic riding horse can fail badly here. Your sheet has to transfer the relationship as far as paper can: how this horse is approached, what he has been trained to accept, and where his limits sit. Only after the handling is clear should the sheet move on to feed, fencing and daily checks.
Lead With How This Mustang Is Caught and Handled
A Mustang's catching routine needs describing step by step, in the order the sitter will do it. Explain how you enter the pen or paddock, whether you carry the halter openly or tucked out of sight, where you walk toward on his body, and what he does when he is unsure, whether that is moving off, snorting, or planting his feet. Say plainly that he must never be chased, cornered by several people, or pursued with ropes or sticks if he will not be caught, and give the fallback instead: leave feed and water, withdraw, and call you. Note who he will accept, because some Mustangs settle for one familiar helper only, and name that person as backup.
Describe the Fencing and Space He Needs
A Mustang's fencing notes deserve their own section because a startled, athletic horse tests boundaries a quieter horse ignores. State the height and type of fencing around his turnout, which gates get chained rather than just latched, and ask for a twice-daily walk of the fence line looking for leaning posts, loose rails and gaps at corners. Say whether he lives alone or with a companion, since a Mustang bonded to one particular horse may fret and pace if that companion is moved while you are away. Include the rule that his space is never entered by visitors, children or dogs during your holiday, however friendly he seems through the fence.
Keep Feeding Simple, Hardy and Unchanged
A Mustang usually thrives on a plain, forage-based routine, and your instructions should protect that simplicity. Give the hay type and amount, the times it is fed, and a firm note that rich grazing, sweet feeds and well-meaning extras are not treats for a horse whose system is built for sparse forage. Explain the water setup, including how the trough is checked for ice or algae and where the hose or spare buckets are kept. If he receives any routine supplement, say where it is stored and how it is measured, and warn the sitter that a Mustang who stops eating is showing something significant, because this breed rarely leaves forage without a reason.
Set the Emergency Lines for a Horse Who Hides Trouble
A Mustang's stoic nature means the sitter needs explicit thresholds rather than judgement calls. Write that a horse who is off his hay, standing apart, sweating, pawing, repeatedly rolling, or favouring a leg earns an immediate phone call, and that visible injury, escape from the pen, or a broken fence is an emergency whether or not he looks hurt. Leave the vet and farrier numbers, your own contact order, and the name of the experienced backup handler who can help catch or load him if treatment is needed. Sharing the whole sheet through a KinsLe Care Pass lets your sitter keep this Mustang's approach rules, fence-line checks and vet number together until you are back.
