Spay and Neuter


In 2014, the Ventura County Board of Supervisors approved a mandatory Spay and Neuter Ordinance (4421-3) requiring all dogs and cats six (6) months and older to be spayed or neutered. The purpose of this ordinance is to control the overpopulation of animals in Ventura County, but there are a number of additional benefits to having your pet spayed and neutered.


Animals who are spayed or neutered:

    1. Tend to live longer, healthier and happier lives.
    2. Are free from ovarian and testicular cancer and have a lower prevalence of certain types of other cancers.
    3. Are less likely to spray and mark territory.
    4. Tend to have less behavior problems due to the absence of testosterone in their system.
    5. Tend to cost the owners less money in the long run.
    6. Are less likely to escape your yard and roam the community.


The cost of a pet license for spayed or neutered animals in Ventura County is considerably less when compared to a pet license for an unaltered/intact animal.


Simply spay or neuter your pet.  If you have been given a notice to comply with this ordinance, you must submit proof of sterilization within sixty (60) days from the time of notice.  Visit to submit documents.

Support our department’s efforts to provide no-cost spay/neuter services to intact animals who are being reclaimed by their owners as a result of having ben brought to the shelter as a lost or stray pet.  Your purchase of a Pet Lover’s license plate through the Department of Motor Vehicles (DMV) helps support these efforts.
