During the last few years a disease has been quite prevalent in the south which has been called “Black Tongue” whether this is a distinct disease or merely the symptom of some other disease is as yet not known. The principal symptoms are congestion of the tongue and mouth which causes the black color, this usually leads to ulceration of the mouth and the ulceration frequently extends so as to involve the entire digestive tract. There is great weakness and emaciation with death in a few days. Very few animals recover. Besides these symptoms many others have been reported but they vary so much in the different cases that they have caused great doubt as to “Black Tongue” being a distinct disease. The symptoms given might be Dumb Rabies, page 225; Canker of the Mouth, page 237; Hook Worm, page 243; or Sore Throat, page 232. In cases of so called “Black Tongue” we would advise comparing the symptoms with those of the above diseases. CHAPTER II.—PART IV. DISEASES OF THE HEAD AND NERVOUS SYSTEM Apoplexy DEFINITION.—A sudden, partial or complete loss of consciousness and power of motion, occasioned by determination of blood to the head. CAUSES.—Pressure on the brain, from a congested state of the blood-vessels. Fat pet dogs are more subject to an attack than dogs moderately fed and allowed plenty of exercise. SYMPTOMS.—Staggering walk, drowsiness, twitching of the muscles of the face and limbs; these are premonitary symptoms of an attack; or the fit may be sudden, when the dog falls down without power of movement, with loud and irregular breathing, and appears to be dying, but generally, after three or four hours, he gradually recovers. TREATMENT.—The A.A., is the proper remedy, and may be given for the premonitions of an attack, a dose morning and night. If he has had the fit, give a dose at once, and repeat it again after two or three hours, and then morning and night for a time, to prevent a relapse. Dose, one to three drops, according to the size of the dog. ACCESSORY MEANS.—Wherever the fit occurs, if possible, let the dog remain, and apply cold water to the head with sponge. After recovery takes place, care must be taken as to diet, only milk or oatmeal and water should be given for a day or two. Palsy, Paralysis This is not an unfrequent affection in the dog, especially those that are well fed, as pet dogs. It arises from disease of the brain or spinal cord, and is sometimes also the result of disease of the bowels or stomach. SYMPTOMS.—It may occur in one side or part of the animal, and is most frequent in the hind legs, which appear as if the animal had no power over them; he staggers, falls, or lies on the ground, dragging his hind legs after him, unable to stand upon them. TREATMENT.—Give the J.K., two to five drops, according to the size of the dog, three times per day.
