Water-dogs are specially liable to canker of the internal ears, owing to the fluid producing irritation by not being properly dried out of the ear. The animal shakes his head continually, thereby exciting inflammation of the membrane or lining of these organs. All dogs with long pendulous ears are susceptible to canker. So whenever a dog is observed to be constantly engaged in shaking his head and making frequent attempts to scratch his ear, you should institute a careful examination of the interior of the passage leading into the head, and if you discover that the lining is red and inflamed, such evidence is conclusive that the disease exists.

Treatment

Administer a good dose of physic to begin with, and then drop a little of the following mixture into the ear that is affected once a day: - Opium tincture, one drachm; liq. plumb. dia. one drachm; olive oil, one ounce; glycerine, one ounce. Mix. When you have done this, hold the head for some time to prevent the animal shaking it Colic and Inflammation of the Bowels is also a frequent complaint among the canine race; the symptoms being intense pain, aggravated at intervals to such an extent that the poor brute will howl in the most appalling manner. The back will be arched, the legs drawn together; he will suddenly start up with a sharp painful moan, and then lying down again, appear at rest for a short interval The start and moaning, however, are repeated in a few minutes with increased intenseness, and gradually become more and more prolonged as the disease advances. The nose appears natural; there is no fever; all the evidences of pain are situated in the belly.

Treatment

First, good dose of physic, followed up with tincture of opium one drachm, sweet spirits of nitre one drachm, given in a little warm water every three hours. Apply hot fomentations, or, better still, put the animal in a bath and keep it there until you observe signs of relief.
