As it has been said of the human being that great power and exertion of the mental faculties are sometimes connected with a tendency to epilepsy, and, as violent emotions of joy or of grief have been known to be followed by it, I can readily account for its occurrence in the young dog, when frightened at the chiding of his master, or by the dread of a punishment which he was conscious that he had deserved. Then, too, I can understand that, when breaking loose from long confinement, he ranges in all the exuberance of joy; and especially when he flushes almost his first covey, and the game falls dead before him, his mental powers are quite overcome, and he falls into an epileptic fit. The treatment of epilepsy in the dog is simple, yet often misunderstood. It is connected with distemper in its early stage. It is the produce of inflammation of the mucous passages generally, which an emetic and a purgative will probably, by their direct medicinal effect, relieve, and free the digestive passages from some source of irritation, and by their mechanical action unburthen the respiratory ones. When it is symptomatic of a weak state of the constitution, or connected with the after stages of distemper, the emeto-purgative must be succeeded by an anodyne, or, at least, by that which will strengthen, but not irritate the patient. A seton is an admirable auxiliary in epilepsy connected with distemper; it is a counter-irritant and a derivative, and its effects are a salutary discharge, under the influence of which inflammation elsewhere will gradually abate. I should, however, be cautious of bleeding in distemper fits. I should be fearful of it even in an early stage, because I well know that the acute form of that general mucous inflammation soon passes over, and is succeeded by a debility, from the depression of which I cannot always rouse my patient. When the fits proceed from dentition, I lance the jaws, and give an emetic, and follow it up with cooling purgative medicine. When they are caused by irregular and excessive exercise, I open the bowels and make my exercise more regular and equable. When they arise from excitation, I expose my patient more cautiously to the influence of those things which make so much impression on his little but susceptible mind.
