§ 90.042  IMPOUNDMENT OF ANIMAL THAT HAS BITTEN OR ATTACKED.
   (A)   When an owner of an animal has been notified that animal has bitten or attacked any person, within 24 hours, that owner shall place the animal under the care and control of the animal control officer for a period of not less than ten days.
   (B)   At the end of the ten-day period, the animal control officer shall examine that confined animal and if cleared, the animal may be reclaimed by the owner. The owner is to pay all expenses incident to the confinement and examination.
   (C)   If, during confinement, the animal shows signs of rabies or it is known that animal has been exposed to rabies, then that animal may be confined in excess of the ten-day period and for as long a period as is necessary to determine a diagnosis.
   (D)   Any animal that has bitten or attacked and cannot be captured, may be destroyed in such a way as not to destroy the head so that it may be submitted to a laboratory for a rabies examination.
   (E)   (1)   Within 24 hours of the bite, if an owner of the animal that has bitten or attacked can provide proof of a current rabies vaccination given within 30 days prior to the date of the bite or attack, then he or she may prevent the euthanization of the animal by order of the health authority or a veterinarian from the board of health.
      (2)   Any animal that has bitten any person may be euthanized by order or the health authority, if in its opinion and based on sound medical judgements, a greater risk is present if the animal is not euthanized. The health authority shall take into consideration the following factors:
         (a)   History of the animal, including its exposure to rabies;
         (b)   Vaccination record of the animal;
         (c)   Health of animal;
         (d)   Nature, seriousness and location of bite;
         (e)   Circumstances surrounding the bite, including whether or not the bitten animal provoked it;
         (f)   Tolerance of person bitten to vaccination treatments.
