As it is a constitutional disease, its duration is uncertain, its cure difficult, and its return probable. TREATMENT.—In old cases, give the I.I., each morning, and the J.K., at night, and anoint, once per day, the sore, rough or scabby places, with ZINC OINTMENT. In urgent recent cases, the remedies above referred to may be given, four doses in a day. But in general the treatment first named will suffice. ACCESSORY MEANS.—Strict attention must be given to diet; flesh must be utterly prohibited, except in the case of weak puppies, or when the disease has occasioned great debility, and then broth will be better than solid flesh. To gross dogs a few days’ abstinence will do no harm; they may thus become willing to take boiled rice, which should be offered fresh every day; but if declined, withdrawn at once. If the dog refuse to eat more than three days, an ounce or two of meat (according to his size) may be given to keep him alive, without satisfying his hunger. Vegetable or farinaceous food should still be offered sparingly, and when taken, the morsels of flesh should be discontinued. Do no more washing than is necessary. Dirt scabs, etc., should be removed with olive oil. The dog’s bed should be repeatedly changed, and his kennel well ventilated; he should have free, moderate exercise in the open air, and be fully supplied with fresh water. Boils—Furuncles Boils, which may appear on any part of the body, are small, round, red, hard, painful tumors, with raised centers, from which they supperate. When ripe, the boil should be opened and the pus pressed out. Warm fomentations will hasten the ripening. TREATMENT.—Give A.A., a dose three times per day, one to three drops, according to the size of the dog. If the boil is red and painful, apply HUMPHREYS’ VETERINARY OIL, two or three times per day. The boils should be opened when they have come to a head. Louse—Tick—Flea The dog louse (_trichodectes latus_), the dog tick (_irod ricinus_), and the dog flea (_pulex canis_) are sources of no little torment. They cause considerable irritation, which induces the dog to scratch and rub himself; small pimples are formed, their heads are rubbed off, serum exudes, perhaps matter, and thus sores are produced. Lice are found in every part of the body, but particularly on the head and about the eyes and lips. They do not live on man. Ticks do not infest house dogs. TREATMENT.—Fleas are best removed by means of Persian Insect Powder (Flores Pyrethri), this may be dusted on the dog or better dissolved in alcohol or water and sprinkled or rubbed on, another convenient way is to dust on the powder after a bath and before the hair has entirely dried. As this powder renders the fleas insensible rather than killing them, means should be taken to prevent the fleas getting back on the dog after they have recovered.
