A bandage on a horse's leg lives a hard life: it is stood on, lain on, dragged through bedding, and tested by teeth. Keeping one clean and secure for days at a time is less about clever materials than about a sound build at the start and a strict routine of checks afterwards, because a bandage that slips or tightens unevenly can damage the very tendons it was meant to protect.
Start with a clean, dry leg
Never bandage over dirt, stable stains, or wet hair. Brush or wash the leg first — if the bandage covers a wound, clean the area as your vet directed — then dry it thoroughly, fetlock and pastern included, because trapped damp under padding macerates skin within a day and gives you a second problem under the first. Work on a clean, dry standing area rather than in the bed, so no straw works its way inside as you wrap. If the other foreleg or its pair needs a support bandage for a horse on box rest, build that one with the same care; a horse standing unevenly for days loads the good leg hard.
Padding first, pressure second
The pad is doing the real work: it spreads pressure evenly over the cannon bone and tendons, fills the hollows beside the fetlock, and stops the outer wrap from ridging into the leg. Lay it smoothly with no folds or turned-under corners. Wrap your outer layer over it in even, overlapping turns, working down over the fetlock and back up, keeping the tension consistent — firm enough that the bandage does not slide when you press it, never so tight that the edges bite in. Bandage in the direction that closes over the front of the leg rather than pulling across the back of the tendons. Finish at the top and check: you should be able to slide two fingers under the top edge, the fetlock should be covered without being locked rigid unless your vet has asked for that, and the whole thing should look smooth rather than lumpy. Lumps mean pressure points, and pressure points on a horse's leg become sores.
Keeping it clean through the day
Deep, dry bedding is your ally in the stable; a bandage dragged through a wet bed all night comes off in the morning soaked and filthy whatever you do. Pick the box out more often than usual for a bandaged horse. If the horse goes into a small pen or is hand-walked, an outer protective layer over the bandage keeps mud and bedding out of its edges — but take that layer off back in the stable so the leg breathes and you can see the bandage itself. Check twice a day at minimum: run your hand over it for damp patches, feel whether it has slipped down and bunched around the fetlock, and sniff it — a sour smell through the wrap is a reliable early alarm.
The checks that tell you it is failing
Change the bandage at least once a day, or immediately if it has slipped, got wet through, or started to smell. At every change, read the leg before you rewrap: compare the shape above and below where the bandage sat, feel for heat that was not there yesterday, and look at the wound itself for discharge, proud-looking tissue, or edges pulling apart. Swelling that appears above the bandage, a horse who is suddenly more lame, or a leg that fills around a bandage that was fine in the morning all mean the plan needs reviewing rather than simply rewrapping. Photograph the wound and log each change in KinsLe's Pet Passport and you have a dated visual record to show your vet instead of relying on memory.
