ASTHMA
Cause.—In some instances I believe it is hereditary, although in others no influence of this nature can be discovered. This affection frequently follows organic diseases of the chest. The spasms of difficult breathing may be directly due to irritants inspired into the lungs, such as smoke, gas, or dust and cold air containing infectious matter. Overfeeding frequently produces this condition, as an abnormal distention of the stomach presses against the lungs and causes them to become inactive and spasmodic contraction of the muscular fibers of the bronchial tubes follows. Dogs with narrow chest cavities are predisposed to asthma, which condition is hereditary.
Symptoms.—This disease is attended with difficulty of breathing and a sensation of constriction of the chest, giving rise to wheezing, coughing and general nervousness. The animal becomes emaciated, the hair has a rough, faded appearance, although it will continue to eat well. Constipation is generally associated with this disease.
Treatment.—Place the animal in clean, comfortable surroundings, exercise carefully as violent exercise would tend to aggravate the disease. Feed sparingly on nitrogenous food that is easily digested; also administer Fowler’s Solution of Arsenic, four drops, twice daily. This can be placed on the food, as the dog will take it readily. If the bowels are constipated, give one to two tablespoonfuls of Castor Oil. Good care and careful feeding play a very important part in the treatment of asthma.
