CAUSES.—Constitutional tendency; unsuitable food; want of cleanliness; sudden disappearance of eczema. TREATMENT.—I.I., is the proper remedy, giving once or twice per day. The ears should be washed once a day with warm water and soap. After they are dry, the following lotion should be applied with a sponge; Glycerine one part, HUMPHREYS’ MARVEL WITCH HAZEL two parts, to water three parts. Ulceration of the Nose Ulcerations of the nose are not common in dogs, but they should not be neglected, as they might injure or destroy the sense of smell. They sometimes occur in old dogs, and emit a purulent, or sanious, and most offensive discharge. This condition is attended with pain, noisy breathing, attempts to sneeze, etc. TREATMENT.—C.C., is the proper remedy, and may be given two or three times per day. The nostrils should be washed and syringed with tepid water, morning and night. CHAPTER IV.—PART IV. DISEASES OF THE RESPIRATORY ORGANS Angina—Sore Throat DEFINITION.—Inflammatory swelling of the larynx and trachea. CAUSES.—Exposure to sudden cold when heated; damp lodgings. SYMPTOMS.—The first are generally sneezing, hoarse cough, ears and nose alternately hot and cold, noisy breathing, caused by swelling of the glands under the throat and jaw; difficulty of swallowing. The front of the neck, especially about the larynx, is much swollen; when the swelling is considerable, internally and externally, the breathing sometimes becomes so much embarrassed that the animal dies of suffocation. TREATMENT.—Give A.A., a dose every hour at first, and then every two hours, until relieved. ACCESSORY MEANS.—The frequent application to the throat of cloths dipped in hot water; cold water, frequently renewed, for the dog to lap; cold milk and broth as diet. Catarrh—Coryza—Cold DEFINITION.—As a rule, coryza in the dog consists of inflammation of the mucous membrane of the nose. It is most frequent among dogs that are petted and kept in warm rooms. It may lead to bronchitis and other diseases of the respiratory organs. CAUSE.—Change of temperature, especially in spring, during the prevalence of easterly winds. SYMPTOMS.—Running from the nose and eyes; sneezing; diminished appetite; accelerated breathing; dullness; heaviness; sleepiness. TREATMENT.—C.C., is the proper remedy, a dose, one to three drops, three or four times per day. ACCESSORY TREATMENT.—It will facilitate the cure if the dog is kept in a warm place for a day or two, not allowed to go out at all, and fed upon milk or thin oatmeal gruel. He should also have plenty of water to drink. The nose and eyes should be sponged with tepid water several times a day. Bronchitis—Acute and Chronic
