Recognizing the symptoms and clinical signs of fungal infections on horses’ legs is crucial for early detection and prompt intervention. Here are the common indicators to watch for:

1. Skin Lesions and Crusts: Fungal infections often present as distinct skin lesions, such as circular or irregularly shaped patches. These areas may have a scaly, crusty texture and can range in size from small spots to larger areas of affected skin.
2. Hair Loss and Bald Patches: Affected areas may experience hair loss, resulting in bald patches or thinning hair. This hair loss may be localized or spread across a larger area of the leg.
3. Itching and Discomfort: Horses with fungal infections often exhibit signs of itchiness and discomfort. They may excessively rub or scratch the affected areas, leading to further irritation and potential self-inflicted wounds.
4. Swelling and Inflammation: Inflammation and swelling can accompany fungal infections, particularly in more severe cases. The legs may appear swollen, and the skin around the infected areas may be red, tender, and warm to the touch.
5. Discharge or Moisture: Some fungal infections can result in the production of discharge or excess moisture on the legs. This can range from a clear fluid to a thicker, pus-like substance, depending on the specific infection.
6. Lameness or Difficulty Moving: In advanced cases, where the infection has spread or caused more significant damage, horses may exhibit lameness or reluctance to move. This can be due to pain, discomfort, or the compromised integrity of the hoof or leg structures.

It’s important to note that the specific symptoms and severity may vary depending on the type of fungal infection and individual horse. If you observe any of these signs on your horse’s legs, it’s advisable to consult a veterinarian for a proper diagnosis and treatment plan. In the following section, we will explore the diagnostic and treatment options available for managing fungal infections on horses’ legs.
