Summertime has a tendency to bring sunshine, heat, humidity, and insects to a horse barn. These three things can be hard on a horse’s skin, and can lead to the development of several common issues.

Sunburn

Increased day length and a hotter sun can spell trouble for horses lacking pigment on their face, nose, and ears. Intense sunlight can cause redness, swelling, and increased sensitivity. It can be unsightly and is no doubt painful for the horse.

Certain plants such as ragwort, St. John’s wort, and buckwheat contain chemicals that cause horses to be unusually sensitive to the sun. Medications like tetracycline also can make horses more photosensitive.

If your horse is showing signs of sunburn, the first and most logical step is to limit exposure to the most intense hours of sunlight by stabling during these times. Sunscreen or zinc oxide is effective for horses and can be used in the affected areas of the nose and face. Many grooming products and fly sprays might have sunscreen already added
