    Leash rules

    Boulder regulates by HAND-HELD rather than by feet: there is no numeric length limit anywhere in the rules. A leash must be hand-held at all times unless the dog is Voice and Sight registered and you're on an approved trail. And there's a Trailhead Leash Program: you must leash the moment you leave the vehicle at any OSMP trailhead, so the walk from the car park is always leashed regardless of tags.

    Licensing & vaccination

    Beyond standard Colorado requirements, Boulder adds its own document for off-leash use: every dog needs a Voice and Sight tag, registered per dog and expiring 31 December each year. Registration costs $13 for a city resident, $33 county, $75 non-county, but renewal in the 1 November to 31 January window drops that to $5, $20 or $30. Additional dogs are $10 each and additional guardians $5. Miss the renewal window and you pay full registration price again rather than the renewal rate, which for a walker with a client list is a real avoidable cost.
