dermatitis, often referred to as “dermatophytosis”,
“rain rot”, “scratches”, or “dew
poisoning”, is a common problem in horses living in the
southeast, especially during the warm and wetter months of the
year. The presence of fungal organisms on your horse’s skin
can cause irritation, itching, and even open sores. Once an area
in the skin becomes compromised or open it invites more opportunistic
fungal organisms, which further accentuate the infection. Fungal
infection of the subcutaneous tissues can result in considerable
swelling, pain, and lameness. It is also important realize that
even skin which appears normal may be infected.

Equine Clinic has developed a treatment protocol which attempts
to accomplish all of these goals. For treatment of fungal dermatitis, we recommend:
a heavy lather of AEC Antifungal Shampoo to the entire
horse. The shampoo is very concentrated, so only a small
of the shampoo (with lots of water) is required. Let the
shampoo sit for 15 minutes.
15 minutes, rinse your horse with warm water. Dry all areas

every 5 days as necessary.

immunostimulant, such as EqStim®. Call the office
