Horses, like humans, can develop various skin conditions, and summer sores are one of the most common and frustrating issues horse owners face during the warm weather months. Summer sores, also known as sweet itch or seasonal recurrent dermatitis, are a type of allergic reaction that affects horses, causing intense itching, redness, and inflammation on their skin. As a horse owner, it’s essential to understand the causes of summer sores to provide effective treatment and prevent future occurrences.
What Causes Summer Sores in Horses?
Summer sores are caused by an allergic reaction to the saliva of the midge, a tiny flying insect that is prevalent during the summer months. The midge’s saliva contains a protein that is highly allergenic to horses, causing an intense immune response and subsequent skin irritation. The reaction is often exacerbated by other factors, such as humidity, heat, and wind, which can increase the horse’s sensitivity to the midge’s saliva.
Other Contributing Factors
In addition to the midge’s saliva, other factors can contribute to the development of summer sores in horses. These include:
- Genetic predisposition: Some horse breeds, such as Thoroughbreds and Warmbloods, are more prone to developing summer sores.
- Environmental factors: Horses that live in areas with high midge populations or are exposed to other allergens, such as pollen or dust, may be more susceptible to summer sores.
- Imbalanced diet: A diet lacking essential nutrients, such as omega-3 fatty acids, can weaken a horse’s immune system and increase their susceptibility to allergic reactions.
In the next section, we will explore the symptoms and diagnosis of summer sores in horses, as well as treatment options and prevention strategies.
What Causes Summer Sores in Horses?
Summer sores, also known as sweet itch or sweet itch dermatitis, are a common problem in horses, particularly during the summer months. These sores are caused by an allergic reaction to the saliva of the biting midge, a type of insect that is prevalent during the warmer months. In this article, we will explore the causes of summer sores in horses, as well as the symptoms, diagnosis, and treatment options.
The Biting Midge
The biting midge is a small, biting insect that is found throughout the world. It is attracted to the warmth and moisture of a horse’s skin, and feeds on the horse’s blood. The saliva of the biting midge contains an allergen that causes an allergic reaction in some horses, leading to the development of summer sores.
The biting midge is most active during the summer months, when the weather is warm and humid. It is most commonly found in areas with dense vegetation, such as pastures and fields, and is particularly prevalent in areas with standing water.
The Allergic Reaction
The allergic reaction caused by the biting midge’s saliva is a complex process that involves the immune system. When a horse is bitten by a midge, the saliva is injected into the skin, triggering an allergic response. This response causes the horse’s immune system to release chemicals, such as histamine, which lead to the development of symptoms such as itching, redness, and swelling.
The allergic reaction can occur within minutes of the bite, and can last for several hours or even days. In some cases, the reaction can be severe, leading to the development of blisters, hives, and other skin lesions. (See Also: Why Are Arabian Horses So Ugly)
Symptoms of Summer Sores
The symptoms of summer sores in horses can vary depending on the severity of the allergic reaction. Common symptoms include:
* Itching and scratching of the skin
* Redness and swelling of the skin
* Blisters and hives
* Skin lesions and ulcers
* Excessive scratching and rubbing of the skin
In severe cases, summer sores can lead to secondary infections, such as bacterial or fungal infections, which can further complicate the condition.
Diagnosis of Summer Sores
Diagnosing summer sores in horses can be challenging, as the symptoms can be similar to those of other skin conditions. However, a veterinarian can diagnose summer sores by performing a physical examination and taking a complete medical history.
A veterinarian may also perform a skin scraping or biopsy to rule out other skin conditions, such as skin cancer or fungal infections. In some cases, a veterinarian may prescribe a skin test to confirm the diagnosis.
Treatment of Summer Sores
Treatment of summer sores in horses typically involves a combination of medications and lifestyle changes. Common treatments include:
* Antihistamines: These medications can help relieve itching and scratching.
* Corticosteroids: These medications can help reduce inflammation and itching.
* Topical creams and ointments: These can help soothe and calm the skin.
* Shaving and clipping: Removing hair from the affected area can help reduce irritation and scratching.
* Fly repellents: Applying fly repellents to the skin can help deter biting midges.
In severe cases, a veterinarian may prescribe antibiotics or antifungal medications to treat secondary infections. In some cases, a veterinarian may recommend a course of immunotherapy to help desensitize the horse to the midge’s saliva.
Prevention of Summer Sores
Preventing summer sores in horses is often easier than treating them. Common prevention methods include:
* Using fly repellents: Applying fly repellents to the skin can help deter biting midges.
* Wearing protective clothing: Wearing protective clothing, such as a fly mask and fly veil, can help prevent bites.
* Avoiding areas with high midge populations: Avoiding areas with high midge populations can help reduce the risk of bites.
* Using midge traps: Using midge traps can help reduce the midge population and reduce the risk of bites.
In addition to these prevention methods, horse owners can take steps to reduce the risk of summer sores by maintaining good horse care practices, such as regular grooming and cleaning of the skin.
Conclusion
Summer sores in horses are a common problem that can cause significant discomfort and distress. By understanding the causes, symptoms, diagnosis, and treatment options for summer sores, horse owners can take steps to prevent and manage this condition. With proper care and attention, horses can recover from summer sores and lead healthy, happy lives.

Frequently Asked Questions
What are summer sores in horses?
Summer sores, also known as sweet itch or sweet itch dermatitis, are a common skin condition that affects horses, particularly those with a white or light-colored coat. They are caused by the bite of certain types of flies, such as the Culicoides midge, and can lead to intense itching, scratching, and skin lesions.
What are the common causes of summer sores in horses?
The primary cause of summer sores in horses is the bite of the Culicoides midge, which is attracted to the sweat and body heat of horses. Other factors that can contribute to the development of summer sores include allergies, skin irritation, and poor fly control measures. Horses with a white or light-colored coat are more prone to developing summer sores due to their increased sensitivity to fly bites.
Can summer sores be prevented in horses?
Yes, summer sores can be prevented in horses by taking a few simple precautions. These include using fly repellents, such as sprays or creams, to deter flies from biting, and providing adequate shelter and fly control measures, such as fans or misting systems, to reduce fly activity. Regular grooming and skin care can also help to reduce the risk of summer sores by removing any irritants or allergens that may be present on the skin.
How are summer sores treated in horses?
The treatment of summer sores in horses typically involves a combination of topical and systemic therapies. Topical treatments, such as creams or ointments, may be applied to the affected area to reduce itching and inflammation. Systemic treatments, such as antihistamines or steroids, may be administered to reduce itching and inflammation from the inside out.
