All dogs, cats and ferrets 4 months of age and older that live in the City of Lewisville must have a current registration with the city.
Payment for your license is due upon expiration of your current license. If you are licensing for the first time, you must purchase a license within 10 days of obtaining a pet over the age of 4 months.
Licenses are valid for 1 or 3 years from date of purchase. A three-year license is only available if the pet received a three-year rabies vaccination in the last 6 months.
