No person or owner shall chain or leash an unsupervised dog outside for a period longer than 1 (one) hour unless the chain is at least 12 feet long so as to allow for adequate exercise and freedom of movement. Said dog must also be contained on the owner's premises. The chain shall be attached so as to avoid entanglement. If an animal is found to be entangled Animal Control has the authority to do whatever is necessary to rescue said animal. (Ord. O-2019-0904, 9-17-2019)
