This is a very common form of mange, though often confused with non-parasitic eczema.
The mange mite is known as Sarcoptes canis, and takes up its abode upon the superficial dermoid structures.
The irritation thus induced, causes the dog to bite and scratch the part, ending in the production of a raw, weeping surface, extending from point to point, unless something is done to check the ravages of the mites. With licking, biting and scratching, these parasites are transferred as indicated, and an artificial form of eczema induced.
The diagnosis can be confirmed by microscopic examination of the under surfaces of the crusts upon the sores.
Being contagious, keep the diseased dog from healthy ones until cured.
All fittings, clothing, and other appliances likely to have been in contact with the diseased dog ought to be thoroughly scalded with boiling water and soda.
Short-coated dogs are more readily curable than heavily-coated varieties.
Wash dog twice weekly, and after thoroughly drying, dress all over with a dressing, composed of 4 ounces of flowers of sulphur, 1/2 ounce of oil of tar, and a pint of train, or colza oil.
This dressing should be washed off in about three or four days, and repeated until cured.
A bath of sulphurated potash is a capital remedy.
Add an ounce of sulphurated potash to every ten gallons of tepid water.
In some instances it is advisable to clip the dog, thus facilitating the penetration of the dressing.
Almost every kennel man and doggy man has his so-called mange cure, but the first principles are to make a diagnosis of the complaint under which the animal is labouring.
