It shall be unlawful for any owner of any animal to keep such animal if it is known to have a contagious disease unless the animal is under the current treatment of a licensed veterinarian. If any animal impounded under the provisions of this chapter is found to be suffering from rabies or is inflicted with hydrophobia, mange or other infectious or dangerous disease, it shall not be released. The animal safety officer may order that an incurably contagious or harmful animal be destroyed, subject to appeal to the city administrator. (Ord. 436, 3-1-1999)
