Horses face a wide range of skin conditions throughout their lives. Understanding the most common issues—and how to support healthy skin—helps you keep your horse comfortable and their coat looking its best.
Common Horse Skin Issues
Rain Rot (Dermatophilosis)
Rain rot is a bacterial skin infection caused by Dermatophilus congolensis. It commonly appears as crusty scabs that pull away with tufts of hair, often along the back, neck, and hindquarters. Wet conditions and compromised skin barriers increase susceptibility.
Scratches (Pastern Dermatitis)
Also called mud fever or grease heel, scratches affect the lower legs and pasterns. Symptoms include crusty lesions, swelling, and sensitivity. Chronic moisture and mud exposure are common contributing factors.
Ringworm
Despite its name, ringworm is a fungal infection, not caused by a worm. It produces circular patches of hair loss and scaly skin. It is contagious between horses and can spread to humans.
Sweet Itch
Sweet itch is an allergic reaction to the bites of Culicoides midges. Affected horses rub and scratch intensely, particularly along the mane and tail. Managing midge exposure is central to controlling this condition.
Hives (Urticaria)
Hives appear as raised, fluid-filled welts across the skin. They can result from insect bites, dietary changes, medications, or environmental allergens. Many cases resolve on their own, though persistent hives warrant veterinary evaluation.
Dandruff and Dry Skin
Flaky skin and visible dandruff can result from environmental factors, grooming product choices, nutritional factors, or underlying skin conditions. Gentle, pH-balanced grooming products and regular grooming help support healthy skin.
Sunburn
Horses with pink or lightly pigmented skin, particularly around the muzzle and face, can sunburn. Protection through shade, fly masks, and appropriate topical products may help reduce exposure.
How Grooming Supports Skin Health
Regular grooming is one of the most effective ways to monitor and support your horse's skin. Daily brushing removes dirt, debris, and loose hair while giving you the opportunity to spot early signs of skin changes.
When bathing is needed, choosing a gentle, plant-based shampoo free from SLS, parabens, and synthetic fragrances helps support the skin's natural barrier without unnecessary disruption.
When to Call Your Veterinarian
Many common skin conditions can be managed with proper grooming and environmental care. However, contact your veterinarian if your horse shows:
- Persistent itching, rubbing, or hair loss
- Open sores, ulcers, or spreading lesions
- Swelling or heat in affected areas
- Symptoms that worsen despite basic care
- Any condition you are unsure about
