_Symptoms._ These are in the main the same as in the larger animals. The early excitement usually takes the form of hyperæsthesia. When lifted, pressed, touched or only approached the dog may growl, howl, snap, cringe, cower or tremble, glancing up meanwhile with anxious or pleading eyes. When later, this gives place to anæsthesia no such interference will draw a response. The motor disorders at the outset are mostly of the nature of tremors or twitching of the muscles of the limbs or of those parts of the trunk corresponding to the seat of the lesion. In exceptional cases spasms or convulsions may be shown. Trasbot records a case of very acute myelitis of the brachial enlargement in which there were clonic contractions of the muscles of the neck, jaws and eyeballs, and grinding of the teeth, which condition lasted for thirty-six hours. When this motor excitement merges into paralysis it usually attacks the hind limbs which are extended backward helpless while the animal pulls himself forward by his fore limbs. Some such cases are restless and in continual movement while others are dull, apathetic and indisposed to move. The precise seat of the paresis or paralysis will be determined by the seat of the lesion as in the larger animals. Thus paraplegia is most common, less frequently hemiplegia, palsy of the fore limb, palsy of a single limb, and monoplegias, about in the order named. Palsy of the tail and sphincters implies a lesion of the lumbar section of the cord and is very offensive in the incontinence of urine and fæces especially in long-haired subjects. _Treatment._ The abstraction of blood is rarely called for in myelitis in the dog. If admissible at all it is in the case of strong, vigorous, plethoric animals which have been attacked in connection with sudden exposure to cold or accidental concussion, and which are presented for treatment at once. Then leeches may be applied to the abdomen or inside of the thigh, or the jugular may be opened with a lancet. Usually on the other hand the patient is fat, lymphatic, and, if a few days have elapsed, even anæmic, while if he has been the victim of an accident the shock and prostration would forbid any depressive measures. Derivation toward the bowels may be sought by purgative doses of calomel or jalap. In case of high fever, cold may be applied (in the form of icebags, evaporating lotions or wet cloths) to the tender portion of the spine. If the attack has followed exposure to cold, salicylate of soda may be given, otherwise the bromide of potassium or camphor. Acetanilid and other antithermic agents may be used with caution. With the abatement of the high fever and the supervention of paresis, if not before, counter-irritants are demanded.
