What is a common allergy for horses?

Horses can have allergies just like humans. One common allergy for horses is an allergy to insect bites, such as from mosquitoes, flies, or gnats. These bites can cause a reaction called insect bite hypersensitivity, which can range from mild itching to severe swelling and discomfort. Other allergies in horses can include allergies to certain foods, such as legumes or grass, environmental allergens like pollen or mold, and even some medications or grooming products. Allergies in horses can be managed through various methods such as avoiding allergens, using antihistamines, or immunotherapy, which involves gradually introducing the allergen in small doses to help reduce sensitivity.
