How To Treat An Open Wound On A Horse

Last Updated on July 26, 2022

As a horse owner or carer, it is vital that you know how to treat an open wound on a horse. Horses can sustain injuries at any time of day or night, and the correct first aid treatment is vital to ensure that the wound heals rapidly and without complications. Let’s find out how to treat an open wound on a horse!

What Is An Open Wound?

An open wound is one that lacerates the surface of the skin, exposing the flesh underneath. For a wound to be classified as open the skin must be broken, unlike bruises and hematomas, where the skin surface remains intact.

Horses can sustain open wounds in a variety of ways, and there are many different types of open wounds. They can cut the skin on any area of the body, and the depth of the wound can vary from a skin graze to a deep laceration that penetrates the organs underneath.

What Is An Open Wound

Types of open wounds in horses include:

  • Surgical wounds, as a result of veterinary surgical procedures. This includes wounds that are sutured and heal normally and those that break down and reopen.
  • Lacerations – wounds with a clean edge where none of the skin is missing
  • Puncture wounds, such as bites, gunshots, and wire penetration injuries
  • Abrasion wounds, where some or all of the skin tissue is destroyed
  • Avulsion wounds, also known as degloving, where the skin is torn away from the underlying tissues
  • Burns and scalds, including toxic chemical burns

How To Treat An Open Wound On A Horse

To know how to treat an open wound on a horse, we first need to understand a little bit about the stages of wound healing. The manner in which any wound heals is split into several stages:

  • Phase 1: The Inflammatory Phase

This occurs immediately after the injury occurs, and is triggered by the mechanisms that cause blood to start clotting in the wound. Although we often think of inflammation as a bad thing, in this situation it is a natural response by the body in response to an injury. Specialist cells are attracted to the wound that can destroy bacteria and debride dead and damaged tissue.

  • Phase 2: The Proliferative Phase

During this stage, fibroblasts are laying down the structures necessary for the wound to heal. First of all a matrix is laid down, over which new capillaries and granulation tissue develop. This appears in the form of a pink, sponge-like tissue that fills in the deficit left by the wound.

  • Phase 3: The Remodelling Phase

In the final phase of wound healing, the healing wound is strengthened and remodeled as new collagen is laid down. For these three phases to be carried out effectively, the wound needs the optimum conditions to enable it to heal. This means that the wound will need to be cared for correctly at each stage to ensure that full and rapid healing can be facilitated.

What Do You Do If You Find A Wound On Your Horse?

The first thing to do is visually inspect the location, depth, and extent of the wound. If there is any likelihood that it has penetrated a vital structure such as an internal organ, the eyes, or a joint, seek veterinary help immediately.

For wounds that only affect the skin, you can carry out some minor first aid at home. If the horse is calm and you have someone to restrain it, apply pressure over the wound with a clean dressing to stem the bleeding. This can be bandaged in place for a short period.

Once the bleeding has stopped you can evaluate and treat the wound. Wash the wound thoroughly with cold water, sterile saline, or a dilute chlorhexidine solution. Never use strong antiseptic solutions on open wounds, as they can delay the healing process.

The hair can be clipped away from the wound if necessary, but avoid getting loose hair inside the wound. A wound barrier gel can be useful to keep the wound protected here.

If the wound looks complex or deep, it may require veterinary attention and suture. Minor wounds can be treated by the application of a clean dressing to prevent flies from contaminating the wound. Infection and movement of the wound will also slow down wound healing.


So, as we have learned, the question of how to treat an open wound on a horse involves keeping the wound clean and free from infection. If the wound can be immobilised or covered it will heal more quickly. Wound healing will be delayed by infection, flies, and excessive movement of the wound site.
