If you have lost your tag or it has become unreadable, please pay the replacement tag fee when you mail your renewal, and a new tag will be mailed with your license registration. Otherwise, a receipt only will be mailed.

We will mail your tag and/or license receipt within 10 business days from the day we receive your completed license application and payment. Please allow an additional 3-5 business days to receive your tag or receipt in the mail. If we have not received correct payment or proper documentation, you will be notified via mail and the processing of your license will be delayed.

Refunds are not available for unused time or if the animal is altered during the licensing period and you paid at the higher rate.

Why should I license?

Licensing helps Animal Services identify family pets, should an animal become lost. The fees from licensing are used to care for animals and investigate complaints about stray animals, among other services. Other goals of animal licensing are to promote responsible pet ownership and to reduce the tragedies associated with lost pets and pet overpopulation.
