🐴 Sweet Itch in Horses (Summer Seasonal Dermatitis)
Sweet Itch is a hypersensitivity reaction in horses caused by the bites of Culicoides midges. Commonly referred to as summer eczema, it typically occurs during warmer months when midge activity is at its peak.
🌿 Clinical Signs
Affected horses experience intense itching, most commonly along the mane, tail, and ventral midline. Persistent rubbing and scratching may result in:
• Hair loss (alopecia)
• Skin lesions, including sores and scabs
• Marked discomfort and restlessness
⚠️ Risk Factors
• All breeds may be affected, although genetic predisposition can influence severity
• Seasonal occurrence, primarily in spring and summer
💡 Management and Prevention
• Minimise midge exposure by stabling during peak activity periods (dawn and dusk)
• Use protective fly rugs, masks, and physical barriers
• Apply appropriate insect repellents and topical treatments
• Maintain skin hygiene by keeping affected areas clean and dry
• Seek veterinary guidance for moderate to severe cases, where anti-inflammatory or anti-allergy therapies may be indicated
🌞 Veterinary Insight
Proactive management before the onset of midge season is essential to reduce clinical severity and prevent secondary skin damage.
