Mange in horses can be a frustrating and uncomfortable condition, both for the animal and its owner. If your horse has been excessively scratching, losing patches of hair, or showing signs of irritated skin, you’re likely searching for answers. Understanding the causes, symptoms, and treatment options can help you take the right steps to restore your horse’s health and comfort.

⚠️ What to Watch For

Mange is a skin condition caused by parasitic mites that burrow into the skin, causing irritation and inflammation. It can affect horses of all ages and breeds, and recognizing the signs early is key to effective treatment. Here are the most common symptoms of mange in horses:

  • Intense itching and scratching
  • Hair loss, often in patches
  • Thickened, crusty, or scabby skin
  • Redness or inflammation of the skin
  • Restlessness or irritability

In severe cases, horses may develop secondary infections due to broken skin from excessive scratching. If left untreated, mange can significantly impact your horse’s well-being and quality of life.

🔍 Possible Causes

Mange is caused by microscopic mites that live on or under the skin. In horses, there are several types of mites that can lead to this condition, including:

  • Sarcoptic mites (Sarcoptes scabiei) – These burrow into the skin and cause intense itching.
  • Psoroptic mites (Psoroptes spp.) – These live on the skin’s surface and can cause severe irritation.
  • Chorioptic mites (Chorioptes spp.) – Commonly found on the lower legs, especially in horses with feathered fetlocks.
  • Demodectic mites (Demodex spp.) – Rare in horses but can occur in immunocompromised animals.

Transmission typically happens through direct contact with an infected animal or contaminated objects like grooming tools, blankets, or tack. Horses with weakened immune systems or those living in unsanitary conditions are more susceptible to mite infestations.

✅ What You Can Do at Home

While mange requires veterinary treatment to fully resolve, there are steps you can take at home to support your horse’s recovery and prevent the spread of mites:

  • Isolate the affected horse to prevent transmission to other animals.
  • Clean and disinfect all grooming tools, tack, and stable equipment.
  • Wash blankets, saddle pads, and other fabric items in hot water.
  • Maintain good stable hygiene, including regular cleaning of stalls and paddocks.
  • Provide a balanced diet to support your horse’s immune system.

While these measures can help manage the condition, they are not a substitute for professional treatment. A veterinarian will need to identify the specific type of mite and recommend an appropriate treatment plan.

💡 When to Call a Vet

If you suspect your horse has mange, it’s essential to consult a veterinarian as soon as possible. Diagnosing mange typically involves a skin scraping or biopsy to identify the type of mite. Based on the diagnosis, your vet may recommend one or more of the following treatments:

  • Topical medications, such as medicated shampoos or sprays
  • Oral or injectable antiparasitic drugs
  • Anti-inflammatory medications to reduce itching and discomfort
  • Antibiotics if secondary infections are present

Early treatment not only helps your horse recover faster but also prevents mites from spreading to other animals. Keep in mind that some types of mange mites, such as Sarcoptes scabiei, can also infect humans, so prompt action is crucial for everyone’s safety.

FAQs

Q: Can mange in horses go away on its own?
A: Mange will not resolve on its own and requires veterinary treatment to eliminate the mites. Without intervention, the condition can worsen and lead to secondary infections.

Q: Is mange in horses contagious to humans?
A: Certain types of mange, such as sarcoptic mange, can be transmitted to humans. It’s important to handle affected horses with care and follow your vet’s advice to prevent zoonotic transmission.
