Laryngitis simply signifies sore throat or inflammation of the larynx.
Causes. - Exposure to cold; standing in a stable where a current of cold air passes; driving rapidly against the wind, etc.
Symptoms. - The first symptoms noticed generally are dullness, slight swelling of the throat and soreness upon pressure. There will be difficulty in swallowing, and when attempting to drink the water will run out of the nostrils. The mouth will be dry and hot, the pulse very quick in severe cases, and there will be a discharge from mouth and nostrils both; the discharge will be colored from the food the animal has been eating, sometimes leading to the mistaken idea of glanders. The breathing will be loud and difficult, and in very severe cases there is danger of choking.
Treatment. - Put the animal in a box stall and give plenty of pure air. Mix equal parts of powdered chlorate of potash and licorice root and place a heaping teaspoonful well back on the tongue three or four times a day, after first rinsing the mouth with cool water. Mix equal parts of turpentine, raw linseed oil, and ammonia and apply to the throat every two hours until the skin becomes tender. If the breathing is very difficult, inject, with a small syringe, a half ounce of fluid extract of lobelia well back on the tongue once every two hours till relieved. Do not attempt to drench or you will strangle the animal. Keep a pail of clean, cool water where the patient can get to it, and feed on bran mash and a little fine hay.
