Licenses are normally valid for a 12-month period. Rabies vaccination must be good through the 12-month term of the license, or the license will expire when the vaccination does.Example: if you purchase your license on May 12, 2014, and the dogs rabies vaccination is valid until July 2015, your license will expire at the end of May 2015.
If you purchase your license on May 12, 2104, and the rabies vaccination expires in November 2014, then your license will expire at the end of November 2014.
