Newcastle's Responsible Pet Owners

The number of cats and dogs licensed in Newcastle continues to grow. That's great news for pets in the city and throughout King County. License fees support the return of hundreds of lost pets to their homes and help give thousands of homeless pets new families every year. Pet license fees also fund investigation of animal neglect or cruelty, spay/neuter programs to reduce pet overpopulation, and community education services. If you license your pet, you can also expect that your pet will be reunited with you should the pet become lost. Purchase or renew a pet license online at the Regional Animal Services of King County website.
