Sooner or later, every horse picks up a wound — on a fence, out in the field, in the stable, or on the way to a competition. A well-stocked first aid kit and some basic knowledge make the difference between acting calmly and improvising. Diagnosis and stitching are the vet's job; this is what you can do yourself until that point.
What Belongs in a First Aid Kit
A usable kit fits in a single sealable box you can grab quickly. Keep it in a fixed spot in the stable and bring a smaller version in the trailer and to competitions. The core consists of supplies to clean, cover, and secure a wound.
| Category | Contents |
|---|---|
| Cleaning | Saline solution or clean lukewarm rinse water, gauze pads, optionally a mild wound disinfectant |
| Covering | Sterile wound dressings, non-stick wound gauze |
| Securing | Synthetic padding/cotton wool, self-adhesive wrap (e.g., cohesive bandage), elastic bandage |
| Tools | Clean scissors with a rounded tip, tweezers, disposable gloves, flashlight |
| Measuring | Thermometer (digital, rectal), optionally a watch for heart rate and breathing |
| Other | Clean towel, garbage bag, notepad, a list of phone numbers |
Add whatever your vet recommends for your specific horse. Don't improvise with ointments or medication on your own: what you put on a wound can affect both its assessment and its healing. Check expiration dates a few times a year, and restock anything you've used right away.
Assess the Situation First
Before you touch anything, take a few seconds to take in the whole picture. Is the horse standing stable, or does it look like it might go down or pull away? Position yourself safely — never directly behind the legs — and have someone hold the horse if possible.
Then look at the wound itself and judge the urgency. Call the vet immediately for:
- Bleeding that keeps flowing or comes out in pulses (in time with the heartbeat).
- A deep or gaping wound, or a wound near a joint, tendon, or the abdomen.
- A wound with visible bone, joint fluid, or a caved-in section.
- Severe, sudden lameness where the horse won't bear weight on the leg.
- A puncture wound, for example from a nail or branch — these look small but go deep.
- Any doubt about tetanus cover: current tetanus vaccination matters for every wound.
When in doubt, call. The phone consultation is usually free and can sometimes save you from a much bigger problem.
Stopping Bleeding
For heavy bleeding, the first step is applying pressure, not cleaning. Place a clean pad or clean cloth on the wound and press down firmly and steadily with the flat of your hand. Don't keep lifting the pad to check: that disrupts clotting. If the material becomes soaked through, place a new pad on top instead of removing the one underneath.
Keep up the pressure until the bleeding eases or the vet arrives. A pressure bandage (padding plus a firmly wrapped wrap) can take over the pressure on a leg, freeing up your hands. Don't use a tourniquet yourself — it can do more harm than good.
Cleaning and Assessing a Wound
If the wound has stopped or almost stopped bleeding and is superficial, you can clean it carefully so you can see what you're dealing with.
- Put on gloves and, if needed, trim away the hair around the wound so it doesn't stick to it.
- Rinse the wound with saline solution or clean lukewarm water until sand, grit, and loose dirt are out. Rinsing works better than rubbing.
- Pat — don't rub — the edges dry with a clean gauze pad.
- Assess the size, depth, and location. Take a photo: useful for the vet and for comparing healing later on.
Don't use harsh agents such as undiluted iodine, hydrogen peroxide, or alcohol on a fresh wound; they damage healthy tissue. A mild wound solution formulated for horses is usually enough. Stitching is generally only useful within a few hours, so don't delay having the vet assess a gaping wound.
Bandaging or Leaving It Open
Not every wound needs to be wrapped. A small, superficial graze in a spot that doesn't move often heals just fine in open air, as long as it's clean. A wound on a lower leg — where there's little skin, a lot of movement, and dirt gets in quickly — actually benefits from a bandage.
Apply a bandage in layers:
- Contact layer: a non-stick wound dressing directly on the wound.
- Padding layer: a generous layer of synthetic padding that spreads pressure and doesn't constrict.
- Fixation layer: a wrap or cohesive bandage, applied evenly and not too tight.
Watch the tightness: a bandage that constricts cuts off circulation. You should still be able to just fit a finger underneath. Preferably wrap a leg bandage over a larger part of the leg so it doesn't slip down, and change it as agreed with the vet — often daily for a fresh, weeping wound. Swelling above or below the bandage, a leg that feels cold, or increasing restlessness are reasons to remove the bandage and consult the vet.
On the Road and at Competitions
The same principles apply at a competition or during transport, but conditions are trickier. Keep a compact kit in the trailer, and know in advance where the on-duty vet or the first aid post is located on the grounds. Also note down the number of your own vet and, for longer trips, of a clinic near your destination. A calm, familiar voice and a trusted halter help a frightened horse more than speed does.
In Short
A first aid kit doesn't need to be big, but it does need to be complete, clean, and quick to reach — and restocked as soon as you use something. For a wound, first assess the severity and your own safety, stop bleeding with pressure, clean superficial wounds with saline or clean water, and bandage only where it helps, without constricting. For deep wounds, ongoing bleeding, joints, puncture wounds, doubts about tetanus, and anything you're not sure about, the vet is the right source. Discuss at the annual check-up which supplies belong in your kit.
