Nobody can tell if a horse is likely to develop dermatitis since there are no predisposing factors. Some horses may randomly develop an allergy or sensitivity toward a substance (allergen). Dermatitis is more of a reaction than a disease classification and may be associated with respiratory and/or digestive conditions. If your horse experiences symptoms only during the summer months, it is likely that a seasonal allergy is to blame. This means your horse is likely to suffer the same symptoms in following summers.
A horse with severe dermatitis will usually demonstrate scratching, rubbing, chewing, and/or biting in the affected region. This is the horse’s attempt to relieve the itch that usually accompanies the condition. Other signs such as hives (urticaria), papules, scales, and crusts are also indicative of dermatitis. Prolonged irritation of the skin is often accompanied by a loss of luster in the horse's coat.
If your horse has been found to be allergic to a certain substance/substances, then avoiding contact with or exposure to the substance will help alleviate symptoms. For example, a horse that is sensitive to the bites of gnats or midges should be kept in the stable before mid-morning and after mid-afternoon, and insect repellent should be used.
Horses with severe or chronic skin conditions are sometimes given cortisone treatment, which may help alleviate the condition. You should consult your veterinarian for proper and appropriate treatment of your horse's skin condition.
Here are some overall suggestions for improving skin health and helping your horse maintain a healthy skin and coat.
* Ensure that your horse gets daily exercise to improve circulation to the skin.
* Maintain regular veterinary checkups
* Avoid excessive use of common anti-inflammatory medications used to treat dermatitis (such as cortisone) as they actually promote skin tissue degeneration when used on a chronic basis.
* Discuss your horse’s overall health with your veterinarian.
