Senior License Fees

Senior citizens aged 65 and older are eligible for one free license. Licenses for additional pets are standard price. A free license is also available for service dogs, guide dogs and police dogs.

Free renewals are required for all free licenses and for lifetime licenses to confirm the owner information and update the pet's rabies vaccination certificate.

If you qualify for a free license or renewal, you may obtain the license by mail, by fax (888-738-5556) or by submitting electronic copies of your documentation by email. Please note that the online payment system does not support free licenses.
