First Aid Kit Contents
A well-stocked equine (and human) first-aid kit should be kept in a place
where it is easily accessed. Any used or out-of-date items should be
replaced as soon as possible.
The basic items any equine first-aid kit should include are:
Thermometer (a digital one is more accurate)
Petroleum jelly (to use as lubrication for thermometer)
Salt (for saline solution, used to soak a horse's foot in case of an infection or abcess)
Cotton wool (for cleaning wounds, not dressing them)
Animalintex/poultice dressing. Even disposable nappies/diapers can be cut and used as a poultice as they draw moisture out of wounds. Regular poultice looks like clay and is lathered on the affected area and left to dry naturally. Some will wrap the poultice in wet paper towels to keep it from drying out.
Gamgee, to be used as padding underneath bandages
Sharp, clean scissors, reserved for first aid kit only
Clean bucket, reserved for first-aid kit only, for washing out wounds
Clean sponge, reserved for first-aid kit only
Antiseptic cream, powder, gel or spray
Bandages - 4x stable bandages, and some rolls of self-adhesive vet wrap
Latex/medical gloves, unused
Soap and nail brush to scrub your hands
Your veterinarian's and farrier's telephone and emergency numbers.
A paper and pencil
Suitable box/container for all of the above, to keep them clean and tidy.
If your horse will be doing strenuous or risky work, it is always good to have a leg brace/stabilizer and/or a few short planks of wood on hand, in case of a broken leg.
