What Causes Rain Rot in Horses & What Are the Symptoms?

Rain rot in horses is caused by the bacteria Dermatophilus congolensis. This bacteria is commonly found in soil and can also be transferred to an animal through an insect bite when the insect is carrying the bacteria, but Dermatophilus isn't activated until water is introduced. A horse can readily pick up the bacteria walking in the meadow, and until lesions appear, you don't realize it's there. Crusty, scabbed skin is a telltale sign that the infection has started. The symptoms of rain rot in horses include the following:

  • Matted hair
  • Hair standing up or on-end
  • Unusually warm skin
  • Crusted, scabby, thick skin
  • Skin that peels easily
  • Obvious pain in the affected area

Horse Wound Care for Common Injuries

Horses will be horses, and that can mean getting hurt in a variety of ways. It can be scary to see such a magnificently powerful animal suffering with pain. What are the common wounds horses sustain, and what can be used to clean and help manage irritation that result from the wounds? Here are four categories under which most horse wounds fall:

Scrapes and Abrasions

Whether in the stall or the meadow, horses will get an array of small wounds that aren't serious problems unless the wounds become infected. Staphylococcus infections can be deadly, so it’s important to find and tend to these wounds during daily grooming. Horse wound care spray with HOCl can help manage the irritation associated with minor scrapes and abrasions.


Lacerations are a bit more alarming because the horse could lose large amounts of blood. That isn't abnormal and is not necessarily cause for worry. These wounds are often jagged or ragged and sometimes appear far worse than they are. Horse wound care should include rinsing the laceration with water to examine the depth of the injury. If it is very deep, it may require stitches. If not, an ointment or horse wound spray containing hypochlorous acid (HOCl) can be used to clean and manage irritation from minor lacerations.


Punctures are more difficult to treat because it can be difficult to see all the damage. With scrapes and lacerations, you can see the injury when grooming the horse. A puncture wound caused by a bucket hook or other piercing object may leave a deep wound, making it easier for bacteria to travel deep into the animal’s body. Thorough washing of the affected area — irrigated by a professional if the puncture is deep — is the best place to start. A topical solution containing HOCl may be prescribed, and a horse wound spray may be used.

What is Hypochlorous Acid (HOCl)

An ideal disinfectant and sanitizer, hypochlorous acid is endogenous and effective against many microorganisms. Endogenous means it originates from within the white blood cells of mammals, for the purpose of fighting infections in the body. HOCl naturally destroys bacteria and viruses that cause infection after a wound occurs. Unlike many antibacterial agents, hypochlorous acid complements mammals' cells. That means a horse wound spray containing HOCl works with a horse’s system and causes no harm as it only enhances the body's natural ability to heal itself.
