Straight from the code for my county:
ARTICLE VI, Killing or Injuring Livestock, or Poultry or Other Domestic Animals
§ 62-16. Killing or injuring livestock or poultry.
A. It shall be the duty of the animal control officer or other officer who may find a dog in the act of killing or injuring livestock or poultry to kill such dog forthwith, whether such dog bears a license tag or not. Any other person finding a dog committing any of the depredations mentioned in this section shall have the right to kill such dog on sight, as shall any owner of livestock or his agent finding a dog chasing livestock on land utilized by the livestock when the circumstances show that such chasing is harmful to the livestock.
B. The general district court or circuit court shall have the power to order the animal control officer or other officer to kill any dog known to be a confirmed livestock or poultry killer; any dog killing poultry for the third time shall be considered a confirmed poultry killer.
C. If any person, including the animal control officer, has reason to believe that any dog is killing livestock or committing any of the depredations mentioned in this section, he shall apply to a magistrate of the County, who shall issue a warrant requiring the owner or custodian, if known, to appear before the judge of the general district court at the time and place named therein, at which time evidence shall be heard, and if it shall appear that such dog is a livestock killer or has committed any of the depredations mentioned in this section, the dog shall be ordered killed immediately, which the animal control officer or other officer designated by the judge of the general district court to act shall do or removed to another state which does not border on the commonwealth and prohibited from returning to the commonwealth. Any dog ordered removed from the commonwealth which is later found in the commonwealth shall be ordered by a court to be killed immediately.
