Eczema probably comes from both external and internal causes. Among the external causes are improper grooming and cleansing of the skin, exposure of the animal to constant rain and the use of irritant soap. Grease may be caused by clipping the hair about the fetlock in cold weather and cleaning before the hair has entirely dried. Among the internal causes are hereditary disposition, improper diet and use of drugs. TREATMENT.—First clean the sores, removing all dirt, scabs, etc. For this purpose olive oil is better than water as soap and water are apt to cause further irritation. (If about the tail or mane, clip the hair around the sores). Apply Zinc Ointment at night and morning. Give A.A. three time per day for two days, then I.I. instead of the A.A. When in the form of “Grease” on the fetlocks, remove the hair from the sores and cleanse them well. In bad cases the application of a bran poultice cleanses them beautifully. Keep the legs as dry as possible. Feed with relaxing or green food, bran mashes, and less stimulating food, especially in the early stage, and give fifteen drops of A.A. Keep the legs as free from dirt as possible. If the horse is not worked let him have exercise daily, and each night and morning after the leg is cleaned apply Zinc Ointment. Hidebound This condition is not a disease of itself, but a mere symptom of some other disease, most frequently of the stomach; such as a disordered stomach; poor food, or long exposure to rough, stormy weather. It not unfrequently exists in connection with Glanders, Grease, Founder or old disease of the lungs. SYMPTOMS.—It manifests itself by the hair looking rough and unthrifty, without its natural smoothness and gloss; and the skin feels hard, firm and fixed to the flesh. We can most successfully treat it by ascertaining and removing the cause upon which it depends. But in the absence of any special indication, we may give with the best success a dose of fifteen drops of J.K., each morning, and the same of I.I., each night. A few days treatment will generally produce a most marked improvement. Mange (See also Eczema page 21) Mange is a disease of the skin which has much the same appearance as eczema but is caused by parasites while eczema is not. There are three forms of mange in the horse. 1—Sarcoptic mange caused by a burrowing mite which feeds and propagates in the lower layers of the skin. This form is usually found on the head, neck, shoulders and outer parts of the body. 2—Dermatodecic mange caused by sucking mites which live on the outer layers of the skin and suck up serum and lymph. This form is usually found on the inside of the thighs, root of the mane and tail, sheat, etc. 3—Symbiotic mange caused by scale eating mites which live and feed on the surface of the skin. This form is usually found on the feet and pasterns.
