Enteritis is inflammation of the inner or mucous lining of the bowels.

Causes. - Irritating food causing diarrhoea; catching cold or a prolonged case of colic; and sometimes irritating medicines given in the treatment of colic cause it.

Symptoms. - An ordinary observer will sometimes mistake it for colic, but there is a difference. The pain is continuous, while in colic there will be quiet spells. The horse lies down carefully; the pulse is soft at first, but rapidly and gradually grows faster and harder until it becomes small and wiry and then fails altogether. The breathing is hurried, and there is an anxious look out of the eyes. Toward the last the patient does not lie down but continues to walk until it staggers and falls, struggles a few times and expires.

Treatment. - There is little use for the novice to attempt treatment; it is generally fatal. A quart of raw linseed oil and two ounces of laudanum should be given at once. Mix a pound of the best ground mustard with warm water and rub it well into the abdomen, then put a sheet of newspaper over it and put on a blanket to keep it there. Use warm water injections freely. In an hour after giving the oil, if there is pain, begin to give one ounce of laudanum every hour until four more doses have been given. Repeat the oil in two hours without the laudanum. Death or recovery will take place in from six to twenty-four hours.
