Dogs used to the chase, or hunting in scrubby heather, or running much over hard, uneven roads, suffer from sore toes; the parts around the roots of the claws are swollen, inflamed and tender, making the dog lame, and, indeed, almost unable to get about; there is redness between the toes, and sweating or thin serous discharge therefrom.
Such cases are often very difficult to cure. First give a dose of aperient medicine, and keep the dog up, giving him plenty of soft bedding, and a light diet. Foment the part night and morning with warm water, and bathe freely with this lotion: Calomel, 2 scr.; lime water, 12 oz.; mix. Shake the bottle well when using it, which should be done four or five times a day. If the foregoing fail, try Goulard's Extract of Lead, 2 dr.; tincture of arnica, 1/2oz.; distilled water, 1 pint; mix and apply freely four or five times a day. If the case is a very bad one, wrap the foot in a piece of lint saturated with the lotion, and pull over it a chamois leather boot, which the dog can be prevented from gnawing and pulling off by use of a muzzle, over the mouth-part of which a piece of canvas has been sewn.
