Mange in Horses: 2025 Vet Guide by Dr Duncan Houston 🐴🦠

Hello! I’m Dr Duncan Houston, veterinarian and founder of AskAVet.com. Although rare, **mange** can cause serious discomfort in horses. This 2025 guide covers mite types, clinical signs, diagnosis, treatment—including topical dips and oral dewormers—herd hygiene, and prevention to keep skin healthy and your herd mite-free.

🔍 What Is Mange?

Mange refers to skin infestation by microscopic mites, causing intense itching, hair loss, scabs, and thickened skin. Major mite types in horses include chorioptic (leg/feather mange), sarcoptic (body mange), psoroptic (mane/tail), and demodectic (face/facial) :contentReference[oaicite:3]{index=3}.

🩺 Common Types & Signs

• Chorioptic mange: Most frequent; causes itching, crusting, hair loss, especially around fetlocks and lower legs; signs worsen in cooler weather :contentReference[oaicite:4]{index=4}.
• Sarcoptic mange: Highly contagious but rare; intense itching and crusted lesions on head, neck, shoulders; may cause emaciation in severe cases :contentReference[oaicite:5]{index=5}.
• Psoroptic mange: Affects mane, tail, ears; causes severe itching, scabs; eradicated in some regions but still seen with imported horses :contentReference[oaicite:6]{index=6}.
• Demodectic mange: Localized, non-itchy hairless patches usually on face, muzzle; often self-limiting :contentReference[oaicite:7]{index=7}.

🩺 Diagnosis

1. Clinical exam — look for itching, crusts, hair loss.
2. Skin scrapings to identify mite species under microscope.
3. Veterinary labs can confirm via biopsy or specialized tests.

🛠️ Treatment Strategies

Topical Therapy

• Lime sulfur dips: Effective against chorioptic, sarcoptic, psoroptic mites. Repeat every ~12 days until cleared :contentReference[oaicite:8]{index=8}.
• Other acaricides: Fipronil, pyrethroid sprays, selenium-sulfide shampoos can help :contentReference[oaicite:9]{index=9}.
• Clipping affected hair: Especially on feathers to improve treatment efficacy :contentReference[oaicite:10]{index=10}.

Oral Dewormers (Off-label)

• Ivermectin: 200 µg/kg orally, repeated after ~14 days—effective against multiple mite types :contentReference[oaicite:11]{index=11}.
• Moxidectin: 400 µg/kg—shown effective for chorioptic mange :contentReference[oaicite:12]{index=12}.

Supportive Care

• In severe cases, antibiotics or corticosteroids may control secondary infection or inflammation :contentReference[oaicite:13]{index=13}.
• Clean, dry environment with good ventilation helps skin heal.

🛡️ Prevention & Management

• Quarantine new horses until skin is cleared.
• Use separate grooming tools to prevent mite spread :contentReference[oaicite:14]{index=14}.
• Maintain dry, clean stalls to minimize parasite survival.
• Monitor herd for early signs and treat promptly.
• Follow up with skin scrapings and treatment until two negative results.
