The cost for licensing unaltered or fertile pets is higher than for licensing spayed or neutered pets in order to promote sterilization and to reduce pet overpopulation.

Required Paperwork

  1. 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.
  2. Proof of spay/neuter, such as a signed statement from a veterinarian or an 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.
  3. Proof of age, such as a copy of a government-issued identification card, is required to receive the discounted fees for senior citizens age 60 and over.

Your paperwork will not be returned to you, so please retain a copy of your documents for your records.
