If vomiting accompanies the disease, the following prescription should be administered: Diluted Prussic Acid, nine drops; Morphine Hydrochlorate, ten grains; Bismuth Nitrate, one dram; water, quantity sufficient to make three ounces. Give one tablespoonful not oftener than six hours. This should be given a dog weighing forty pounds. Smaller or larger dogs should receive the same medicine in doses proportionate to their weight. When constipation is present, give two to four ounces of Castor Oil. The general medical treatment for Dog Distemper consists of the following: Quinine Sulphate, two drams; Potassi Nitrate, three drams; Zinc Sulphocarbolates, two drams. Mix well and make into twenty-four capsules and give one capsule every two or three hours. This dose should be proportionately increased in dogs weighing over forty pounds, or decreased for dogs weighing less than forty pounds. Of course a difference of five pounds should not be considered. Bathe the nose and eyes several times daily in a five per cent solution of Boracic Acid. When complications, as Chorea or Pneumonia develop, use the treatments as described under their respective headings. ECZEMA (_Surfeit_) CAUSE.—Derangements of the digestive canal, dogs recovering from distemper, or a bitch after whelping, is predisposed to Eczema. Dogs exposed to a sudden chilling of the surface of the body, when heated, frequently develop Surfeit. Sometimes dogs confined to poorly ventilated, damp kennels develop Eczema, or Surfeit. In fact, any condition that tends to cause a sluggishness of the circulation produces impure blood, and eruptions of the skin naturally follow as a result. SYMPTOMS.—This disease generally affects the neck, back, inside the thighs, arms and the abdomen. The skin becomes red, painful to the touch, small pimples form and serum oozes from them. This gradually spreads and the skin becomes raw and ulcerated. The dog will continue to scratch and bite himself violently, producing further irritation, if not properly treated.
