The duration and course of the disease are deceptive. It occasionally proceeds so insidiously that several days are suffered to pass before the owner perceives any marks of disease, or seeks any aid. The duration of the disease is usually from ten to twelve days. It terminates in congestion of blood in the liver, or a gradual restoration to health. The latter can only take place in cases where the inflammation has proceeded very slowly; where the commencement and progress of the disease could be discovered by debility and slight yellowness of the skin, and especially where speedy recourse has been had to medical aid. The predisposing causes of this disease are often difficult to discover. The dog, in warm climates, seems to have a natural disposition to it. As exciting causes, atmospheric influence may be reckoned, sultry days, cold nights, and damp weather. Other occasional causes may be found in violent falls, bruises, and overfeeding. Fat petted dogs that are easily overheated by exertion are often attacked by this disease. The result of the disease depends on its duration, course, and complication. If it is attended to early, it can generally be cured. If it has existed for several days, and the fever has taken on a typhoid character--if the yellow hue is perceptible--the appetite failing, and vomiting ensuing, the cure is doubtful; and, if inflammation of the stomach has taken place, with high fever, vomiting of blood, wasting away, and fits occurring, there is no chance of cure. When simple jaundice alone is visible, a moderate laxative of sulphate of magnesia and tartaric acid, in conjunction with some aromatic and mucilaginous fluid, or, quite in the beginning of the disease, an emetic, will be found of considerable service; but, when the yellow colour has become more intense, and the animal will no longer eat, and the fever and weakness are increased, it is necessary to give calomel, tartar-emetic, camphor, and opium, in the form of pills, and to rub some strong liniment on the region of the liver: the doses of calomel, however, must be very small. If inflammation of the stomach appears, mucilaginous fluids only must be given. Bleeding may be of service in the commencement of the disease, but afterward it is hurtful. This is an account of hepatitis as it occasionally appears, and particularly on the Continent; but it does not often assume so virulent a character in our country. There is often restlessness, thirst, and sickness, accompanied by much prostration of strength; or general heat and tenderness. Occasionally there is purging; but much oftener constipation, that bids defiance to almost every medicine. The principal or almost only hope of cure consists in bleeding, physicking, and blistering on the right side.
