The skin of a horse is not only the largest organ of the body but also an important shield against environmental influences. However, despite its robustness, the skin of many horses can be susceptible to various diseases that can affect both their well-being and performance. In this article, you will learn everything important about common skin diseases in horses and how to prevent them.
Common Skin Diseases in Horses
- Greasy Heel (Mauke)
Symptoms: Typical signs are redness, swelling, crust formation, and in severe cases even oozing wounds. Affected horses often show pain and lameness.
Risk Factors: Horses kept in wet or unclean stables or spending a lot of time on muddy ground have an increased risk of developing Greasy Heel. Horses with long fetlocks or dense fetlock hair are particularly at risk, as moisture and dirt can accumulate more easily there.
Treatment: Careful cleaning of the affected areas, drying, and applying antiseptic creams are often the first measures. In severe cases, veterinary treatment is necessary.
- Dermatitis
Dermatitis is a general term for inflammatory skin diseases and can be caused by various factors such as insect bites, allergies, chemical irritants, or skin irritations.
Symptoms: Redness, itching, scaling, and bald spots are common signs. With severe itching, horses may rub themselves raw, worsening the condition.
Causes: Dermatitis can be triggered by allergic reactions to insect bites (e.g., midges or flies), certain feed, plants, or grooming products. Insect bites occur more frequently in the summer months and can lead to so-called "summer eczema."
Treatment: Allergic dermatitis often responds to anti-allergic preparations and anti-inflammatory medications. Additionally, allergy-triggering factors should be avoided as much as possible. The use of insect repellents can also help.
- Fungal Infections (Dermatophytosis)
Fungal infections, often referred to as "ringworm," are contagious and spread quickly, especially in stables with many horses. They frequently occur in winter or in humid climates, as fungi prefer a moist environment.
Symptoms: The skin shows bald, scaly patches often accompanied by intense itching. The affected areas are usually round and clearly defined.
Risk Factors: A weakened immune system, insufficient hygiene, or the use of shared grooming tools or tack increase the risk of fungal infections.
Treatment: Affected horses must be isolated to prevent the spread of the infection. The veterinarian can prescribe antifungal agents, and all items that come into contact with the infected horse should be thoroughly disinfected.
- Eczema (e.g., Summer Eczema)
Summer eczema is a chronic allergic reaction to insect bites, especially from midges. It mainly occurs in spring and summer and primarily affects horses kept on pasture.
Symptoms: Horses suffer from intense itching, often shake their heads, and rub against fences or trees. This leads to open wounds and crust formation, especially on the mane, tail, and belly.
Treatment: In addition to relieving symptoms with cooling ointments and insect protection measures, adjusting the horse’s management (e.g., turnout in early morning hours or protective sheets) helps control summer eczema.
Prevention of Skin Diseases
Good stable hygiene and regular care are key to preventing skin problems in horses. Here are some tips that can help:
- Clean and Dry Housing: Regular cleaning of the stall and avoiding muddy floors are essential to prevent diseases like Greasy Heel. Especially in the damp autumn and winter months, stables should always be well bedded and ventilated.
- Regular Coat Care: Daily brushing and grooming remove dirt, dead skin cells, and parasites. Good coat care also supports skin health and helps detect changes early.
- Insect Protection: Effective insect protection is essential in the summer months to prevent insect bites and related skin diseases such as dermatitis and summer eczema. Insect protection sheets, sprays, and regular washing of the horses help keep insects away.
- Healthy Nutrition and Strong Immune System: A balanced diet not only contributes to the overall health of the horse but also strengthens the immune system, which in turn reduces the risk of skin diseases. Minerals such as zinc and biotin are especially important for healthy skin and coat.
- Hygienic Precautions with Infections: In cases of fungal infections and other contagious skin diseases, it is important to isolate the affected horse immediately. Shared items such as grooming tools, saddles, or blankets should be thoroughly disinfected.
Conclusion
Skin diseases in horses are not only unpleasant for the animal but can also cause serious health problems if not treated promptly. Careful grooming, clean housing conditions, and a keen eye for early signs of skin problems are crucial to prevent or treat diseases early. By following these measures, you actively contribute to the health and well-being of your horse.
