A. It is unlawful for any owner or custodian of any dog to permit any such dog to run loose or be at large upon any public street, highway, or public place, or upon private property owned by a person or persons other than the owner or custodian of the dog, within the corporate limits of the city unless such dog is controlled.

B. Any animal injured or killed in the street shall be considered as running at large; the animal control officer shall remove all such animals and, at the officer's discretion, take those needing medical attention to a veterinarian. The owner or custodian of any such animal shall be responsible for all expenses of the treatment and of the impoundment. All reasonable efforts will be made to notify the owner or custodian of any such animal prior to the animal being treated and impounded. Injured animals may be destroyed humanely, if it is determined by the animal control officer or a veterinarian that the animal has sustained critical injuries, suffering is extreme, and/or the prognosis for recovery is poor. The animal control officer shall consult with a veterinarian as to the disposition of injured animals, when the animals' prognosis cannot be ascertained with reasonable certainty.

C. All dogs kept at any one location are subject to impoundment and disposal by the Animal Control Officer if animals from that address have been at large on more than four occasions within a 12 month period. It is not necessary all the animals have been at large on at least one occasion. Such animals are considered a nuisance and the correction of that nuisance is accomplished by the seizure and disposal of all dogs located at the offending address.
