Benefits of Licensing Your Pet:

Being a responsible resident and licensing your pet has benefits for you, your pet and the community. The most important reason to license your pet is so it can be located more quickly and safely returned if lost or stolen. Licensing your pet is required by law and the license provides notification that it has been vaccinated for rabies to keep your pet and our community safe. License fees help support animal control services in Mountlake Terrace.

Which Pets Require a License?

  • All cats and dogs that are 3 months of age and over must be licensed and wear their tags. 
  • Additionally, the city requires a license for goats, horses and pigs.
  • Pet owners have 30 days to obtain a license for pets that are new to the City of Mountlake Terrace.
