(a) If any dog is not redeemed by its owner or harborer within the time allowed for redemption as specified in § 2-207 thereof, the Animal Control Officer, any authorized law enforcement officer, any authorized veterinarian or any duly authorized pound personnel may destroy such dog or sell the same for the costs of impoundment and keeping, plus any registration fee due for the current year.
(b) No dog may be transferred to the permanent custody of a prospective owner unless:
(1) Such dog has been surgically spayed or neutered before the physical transfer of the dog occurs; or
(2) The prospective owner signs an agreement to have the dog spayed or neutered and deposits with the city not less than the lowest nor more than the highest cost of spaying or neutering in the community as determined by the city. Any funds deposited under such an agreement shall be refunded to such person upon presentation of a written statement signed by a licensed veterinarian that the dog has been spayed or neutered. If such person does not reclaim the deposit within six months after receiving custody of the dog, the city shall keep the deposit and may reclaim the unspayed or unneutered dog.
(c) Nothing in this section shall be construed to require sterilization of a dog that is being held by the city and that may be claimed by its rightful owner within the holding period established in § 2-207.
