(2) Any dog which bites a person causing any injury less severe than a "severe injury" whether the person and the dog are on or off the property of the owner or custodian of the dog. Severe injury means any physical injury to a human being that results in muscle tears or disfiguring lacerations or requires multiple sutures or corrective or cosmetic surgery.

(3) Any dog which has killed, seriously bitten, inflicted injury, or otherwise caused injury attacking a domestic animal, horse, or livestock whether the animal and the dog are on or off the property of the owner or custodian of the dog.

(b) Vicious dog means any of the following:

(1) Any dog which inflicts severe injury on or kills a human being whether the person and the dog are on or off the property of the owner or custodian of the dog.

(2) Any dog previously determined to be and currently listed as a potentially dangerous dog, which, after its owner or keeper has been notified of this determination, continues the behavior of a "potentially dangerous dog" as set forth above, or is maintained in violation of the conditions and restrictions placed upon the dog as a "potentially dangerous dog."

(c) A dog shall not be declared potentially dangerous under subsection (a) or vicious under subsection (b)(1) or (2) if the owner or custodian establishes that the actions of the dog with respect to which the declaration is sought were provoked. With respect to harm to a human, "provocation" shall mean that the bite, threat, injury or damage was sustained by a person who, at the time, was committing a willful trespass upon the premises occupied by the owner or custodian of the dog, was committing or attempting to commit a crime upon the person of, or the premises occupied by, the owner or custodian of the dog, or was teasing, tormenting, abusing or assaulting the dog or who has, in the past, teased, tormented, abused or assaulted the dog. The terms "tease, torment, abuse, or assault" as used herein, shall be limited to acts that cause pain, injury, suffering or distress beyond the typical or usual interactions of a human or animal with a dog in a similar environment or circumstance. For purposes of this section, provocation does not include the acts of a person attempting to prevent an animal from physically attacking, mauling, or physically injuring another person or animal. With respect to harm to a human or an animal, a bite, threat, injury or damage shall not be considered provoked if the dog's reaction to the act of provocation was grossly out of proportion to the alleged provocative act. With respect to harm to an animal, an act shall be considered provoked if at the time of the bite or injury, the victim animal was on the property or premises of the dog owner, custodian or keeper, without their knowledge, permission, or consent, whether expressed or implied.

(d) These definitions do not apply to dogs used in military or police work while they are actually performing in that capacity.
