The Lachrymal canals, which originate from the internal angle of the eye, convey the tears into the lachrymal sac, an oval bag, which is a receptacle for tears. It is situated near the angle, and constitutes the upper extremity of the nasal duct. If this duct be obstructed, the tears flow over on the cheek and a small tumor forms in the sac. This is followed by inflammation, suppuration, and the formation of an abscess, which bursts externally and leaves a fistulous opening, through which tears flow from the sac on to the cheek.
Treatment.—Sponge the eye with warm water, and give A.A., morning and night, if the eye or lids are inflamed, or the I.I., if no manifest inflammation is present.
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.
