The city within its jurisdiction shall serve a notice in writing upon the owner or person in charge of a dog, cat or other animal known or suspected to have been bitten by an animal known or suspected of being affected by rabies, requiring the owner or person in charge of the animal to kill it or confine it for a period of not less than six months. Any dog that has been vaccinated by some person legally authorized to do so at least one month before being bitten but not more than one year before shall be confined for ninety days. At the end of the respective periods of confinement such dogs shall be released if examined and declared free of rabies by a licensed graduate veterinarian or by the city dog officer if no veterinarian is available.
