CAUSE.—A sluggishness of the liver, or by the bile duct becoming obstructed by a Calculi (Gall Stone). Either condition suppresses the flow of bile into the bowels, hence the bile is taken up by the blood and causes the visible mucous membranes of the eyes and mouth to become yellowish in color. The predisposing causes are improper and overfeeding, combined with lack of exercise in house dogs, or excessive exercise in hunting dogs, exposure to damp, ill-ventilated sleeping quarters, producing debility, and liver complications are likely to follow. SYMPTOMS.—Appetite varied, thirst great, vomiting occasionally, the dog shows signs of dullness and sleepiness. Then there may be alternate diarrhoea and constipation, the tongue coated and foul in smell, the eyes, mouth, inside of the ears, and the skin inside the thighs and fore legs become very yellow and dry, temperature and pulse not much affected, the dog passes small quantities of dark amber colored urine frequently, due to the bile it contains. In severe cases, the dog loses strength and flesh readily and soon becomes a mere skeleton. Jaundice is often a complication of other diseases, as distemper, indigestion, colic, constipation, etc. TREATMENT.—Endeavor to make the dog as comfortable as possible by placing him in quiet, clean, light and well ventilated quarters. If he is in great pain, apply hot applications over the seat of pain and administer Calomel, one-half grain; Podophyllin, two grains; Powdered Jalap, one dram; Powdered Rhubarb, one dram. Make into six capsules and give one capsule once daily to a dog weighing forty pounds; to smaller or larger dogs regulate the dose in proportion to their weight. The above prescription stimulates the flow of bile from the liver into the bowels, which is very important in the treatment of Jaundice. Tonics are also necessary, and I have found the following very beneficial in treating convalescing diseases, especially where the appetite is poor: Pulv. Ferri Sulphate, one dram; Quinine Sulphate, one dram; Pulv. Nux Vomica, one dram; Pulv. Gentian Root, two drams. Mix and make into twenty-four capsules and give one capsule three times daily just before feeding. This dose should be given to a dog weighing about forty pounds. Smaller or larger dogs should receive the same medicine in doses proportionate to their weight. Feed raw eggs, pure sweet milk, fresh beef finely chopped, cooked vegetables, beef broth, etc. Do not feed too large a quantity at any one time. LUNG FEVER (_Congestion of the Lungs—Pneumonia_)
