Conn. Gen. Stat. § 52-557s: Liability of owner or keeper of horse, pony, donkey or mule.

(a) In any civil action brought against the owner or keeper of any horse, pony, donkey or mule to recover damages for any personal injury allegedly caused by such horse, pony, donkey or mule, such horse, pony, donkey or mule shall not be found to belong to a species that possesses a naturally mischievous or vicious propensity.

(b) In any civil action brought against the owner or keeper of any horse, pony, donkey or mule to recover damages for any personal injury allegedly caused by such horse, pony, donkey or mule, there shall be a presumption that such horse, pony, donkey or mule did not have a propensity to engage in behavior that would foreseeably cause injury to humans. Such presumption may be rebutted by evidence that such horse, pony, donkey or mule previously exhibited behavior that put the owner or keeper of such horse, pony, donkey or mule on notice that such horse, pony, donkey or mule had a propensity to engage in the behavior that allegedly caused such personal injury.

(c) There shall be no cause of action for strict liability brought against the owner of any horse, pony, donkey or mule to recover damages for any personal injury alleged to be caused by such horse, pony, donkey or mule.
