A few years ago, the horse community suffered a fairly strong shock. What had been viewed as a nuisance case in Connecticut was judged, not just once but again on appeal, against the horse owner and in favor of the plaintiff who wanted horses declared “inherently vicious.”
The facts of the case are complicated, and the ruling did not actually condemn all horses. The upshot of it all was that horses, if provoked, will bite (or kick or do other things that may damage a human), and held the horse owner responsible for what happens. There’s still strong feeling on both sides about this, and as a horse owner myself, I hope and pray that someone doesn’t wander into my horse turnout when I’m not there to stop them, and get kicked or stepped on (my lot are not biters as a rule).
