Canker in the Ear This disease consists of an inflammation of the internal ear, followed by ulceration and the formation of matter. It is usually the consequence of some injury, but may also result from excess of food and want of exercise, or from frequent and sudden exposure, as in case of dogs taught to go in the water, among whom it is quite common; it may also come from parasites; fat dogs are more subject to it than others. SYMPTOMS.—The dog manifests pain by shaking his head, scratching his ears, or whining. The internal ear looks red, afterwards may ulcerate; a discharge occurs, and a blackish fluid will be found at the bottom of the ear, sometimes in considerable quantity; there is high fever, which, with the continuance of the discharge, may wear out the dog. TREATMENT.—Wash the ear frequently with warm water, to carefully remove the discharge; afterwards apply some diluted MARVEL WITCH HAZEL. Give A.A., three or four drops, alternately with I.I. The same dose four times per day; it may be successful. Deafness CAUSES.—It is sometimes a sequel of distemper, fever, or inflammation of the brain; it is also due to general debility, an accumulation of hardened wax, old age and canker. TREATMENT.—Examination must be made to ascertain if it is due to the impaction of hard wax; if so, a little warm water and soap may be injected twice a day; after a few days the wax will most likely be softened sufficiently to allow of its removal. If the disorder follows distemper, C.C., should be given; if fever or inflammation of the brain, A.A.; if canker, also the C.C., a dose morning and night. Serous Cyst or Abscess of the Ears This affection of the ear generally arises from some injury, which is followed by an accumulation of a pale, straw-colored fluid between the outside and inside skin of the ear. Sometimes it increases slowly, at others rapidly, so much so that in a few days there will be a quarter of a pint deposited. The best thing is to open the swelling at once with a lancet, at the lowest part of the inside of the ear, and press out all the fluid. If this can be done effectually, adhesion of the two skins takes place without anything else being necessary. But if the discharge has been caused by a severe blow, it may continue for a week or two. Occasionally, if the punctured place is not kept open, the fluid accumulates a second and third time; if such should be the case, it will be advisable to inject a little warm water, and lay the ear in a vessel containing warm water for five or ten minutes, once a day for several days. Give I.I., also morning and night. External Canker External Canker is mostly found on the ears of dogs with short coats; it comes generally on the outside of the ears, beginning at the tips, and gradually extends down to the roots.
