Inflammation of the Kidney is not very common in the dog, but it sometimes occurs from the use of turpentine as a vermifuge. Very rarely there is met with in the kidney a formation of stone, called Renal Calculus, but no means can be used to remove it, nor are there any symptoms which indicate its presence during life.

Inflammation of the Bladder and Urethra is very usual in the dog, and is marked by a discharge of yellow mucus from the end of the penis. This is the result of high feeding generally, though sometimes it comes on from mechanical irritation.

The Treatment is to be conducted by giving saline aperients: sulphate of magnesia, 1/2 to 1 ounce; nitre, 10 to 15 grains ; water enough to dissolve. Mix, and give twice a week.

Balsam of copaiba may be given in obstinate cases, in does varying from 4 to 15 drops, in a little mucilage; but it seldom is retained on the stomach, and the best chance is to give one or two of the capsules now commonly sold, which may be pushed down the throat. When the discharge is clearly in the sheath, a wash of the sulphate of zinc, as here prescribed, may be used. Sulphate of zinc, 10 to 15 grains; rose water, 1 ounce. Mix.
