=Responsibility of the owner.= Dangerous aggressive vice is too self-evident to the buyer to constitute a good cause for annulling a sale, but it has this legal bearing, that the owner who keeps an animal known to be vicious, renders himself responsible for whatever injury to man or beast he may perpetrate. Thus the vicious stallion, bull or dog in a public place which damages person or property, renders his owner liable to the extent of such damages. This, of course, must be largely qualified by the attendant circumstances. The man employed to take care of a horse, knows his habits as fully as the owner, takes his chances and should exercise due precautions to avoid danger. The person who enters a stall carelessly without speaking to the horse, seeing that he stands over, or otherwise responds to his call, is himself to blame if he gets kicked. The attendant who does things to a dangerous or questionable horse for mere bravado cannot blame the owner if he gets himself injured. If a person teases a horse so as to tempt him to retaliate, not only is he responsible for his own consequent injuries, but largely also for the habits of the horse and for such injuries as others may subsequently sustain from him. A dog or a bull shown in a public place, and which breaks loose and injures spectators or others, manifestly renders his master responsible for all such damage. _Treatment of aggressive vice._ In mild dispositions in which the vice is roused by temporary suffering, it may often be cured by removal of the cause of such suffering. Indeed, without the healing of sores under the collar or saddle the vice cannot be arrested. Considerate and gentle treatment, too, will go far to restore confidence and to gradually do away with the aggressive disposition. In wicked stallions castration will usually restore to a good measure of docility. The exceptional cases appear to be those that are hereditarily and constitutionally vicious, or in which the habit has been thoroughly developed and firmly fixed by long practice. Mares, too, which become vicious and dangerous at each recurrence of œstrum, can usually be completely cured by the removal of the ovaries especially if this is done early in the disease.
