Rain Scald
Which is also called rain rot, is caused by the Dermatophilus congolensis bacterium. It is one of the most common skin ailments that a horse may get. It does not cause abscesses and stays on the skin. This fungus requires the absence of oxygen to keep it alive. Rain scald usually occurs when a horse's coat is wet for a long period of time.
The signs of rain scald include matted raised tufts of hair that when removed show pink skin and pus or development of crusty scabs. This ailment is contagious and can be spread by horses sharing the same horse blanket or rubbing posts.
The easiest solution for this condition is to make sure your horse's coat is kept dry during intense weather. Horses kept in humid climates are more likely to get rain scald than horses kept in arid climates. To prevent this you should groom your horse often, especially in the early spring months. Grooming removes the winter coat and makes your horse less likely to get rain scald.
Once you have notice the signs of rain rot you should immediately address the problem. Your vet will advise you on treatments. Your horse will have to be washed using an antimicrobial shampoo. Whilst you are washing the horse you will have to try to remove any scabs that have formed. Be careful because this may cause discomfort to the horse and they may buck or kick. It is very important to remove the scabs so air will reach the infection and dry it up.
You will have to wash your horse for approximately seven days to clear up the rain scald. During the time of treatment it is important to keep your horse in a well ventilated and dry area. Sometimes there are other things that can look like rain scald, including parasites, skin allergies and other bacterial infections. If you're uncertain, you should consult your vet.
Rain scald is a common problem that looks unsightly; but doesn't actually cause your horse much discomfort. To keep your horse healthy make sure you groom them often and treat any conditions promptly.
