(a) Confinement. No other person shall own, keep, harbor or allow to be upon any premises occupied by him or her or under his or her charge or control any dog:
(1) With a known cross, dangerous or ferocious disposition; or
(2) Which has, without provocation, bitten any human within the prior 12 months, without such dog being confined behind a fence from which it cannot escape and being securely chained in such a manner that the animal cannot range within closer than three feet to the property line of the owner, keeper or harborer.
(b) Placarding premises. When any dog is required by this section to be confined it shall also be required that a conspicuous notice be posted at the place of confinement of such a nature as to warn the public of the nature of the dog therein confined. The notice shall consist of a sign that is at least 12" in width and 12" in length. Said sign shall have lettering which is clearly legible and at least 3" high. The sign shall be constructed of durable material and firmly affixed or anchored to the place of confinement.
(c) Exceptions. This section shall not apply to any dog owned by a governmental unit performing in its official duties.
(d) Violation; disposition of dog. Upon conviction of failure to comply with any provision of this section, in addition to the usual judgment of conviction, if it shall appear to the City Council or municipal judge that such dog is not in compliance with this section, the Council or Judge may order the dog out of the city limits or may refuse to issue a license for the dog.
(e) Euthanasia. If a dog deemed dangerous re-offends by putting someone in fear (§ 2-106) or biting someone, the City Council or Municipal Judge may order that said dog be humanely killed and direct the permit authority to enforce that order and the sheriff shall assist as may be requested by the permit authority. Before such order, the dog owner is entitled to a euthanasia hearing before City Council or Municipal Judge within 30 days of the date of the incident. The hearing shall be conducted according to the rules of evidence.
