The licensing fee is $11 per year for each spayed/neutered dog and $14 per year for each non-spayed/non-neutered dog. A 3-year license is also available for $33 for each spayed/neutered dog and $42 for each non-spayed/non-neutered dog. Proof of current rabies vaccination is required and must not expire before October 31st of the licensing year (or final year of 3-year license).
To pay the lower licensing fees, proof of spay/neuter is required. Licenses are valid for the calendar year from January to December. To license your dog, you must complete a Dog License Application (PDF), provide proof of rabies inoculation, proof of spaying or neutering, and pay the appropriate fees. You may license by mail or in person at the Health Department during business hours. If your dog is already licensed, you should receive a notice of renewal in late December of the expiration year. The license can be renewed by mail by noting any necessary changes on the renewal form (i.e. address change, etc.) and enclosing the proper fee payable by check or money order. Dogs that are registered after January 31st are subject to a $5 late registration fee.
