Required Paperwork
- A current rabies vaccination certificate is required if the rabies vaccination on file has expired. Please check your certificate for correct address and pet information.
- Separate proof of spay/neuter, such as a signed statement from a veterinarian or a paid invoice for services is required if the pet has been altered since the last licensing period and you are applying for the lower spayed/neutered license fee.
- A copy of the owner’s ID card is required to receive the discounted fee for senior citizens age 65 and over.
Your paperwork will not be returned to you, so please retain a copy of your documents for your records.
