Dogs in Boulder must wear current city license tags, and Humane Society of Boulder Valley strongly couples licensing with microchipping for identification. Microchips dramatically improve return-to-owner rates for impounded animals across Boulder County.
Under BRC Title 6, every dog over four months kept in Boulder must be licensed annually through Humane Society of Boulder Valley, the city's contracted provider. License fees are reduced for spayed/neutered dogs. While microchipping itself is encouraged rather than universally mandated by the city, it is required for any dog that has been impounded as a condition of return, and the county strongly promotes chips at adoption. A registered microchip allows BPD and animal control to reunite lost pets without lengthy shelter stays. Owners must update contact information when moving within or away from Boulder.
Failure to license is a municipal violation with fines; impound fees are higher for unlicensed or unchipped dogs, and second-time impounds may trigger mandatory chipping.
