Dog owners who want to participate in Boulder's Voice and Sight Control program, known as the green-tag program, can start taking classes June 2.
All green-tag holders who wish to continue taking their dogs off leash on Boulder open space, as well as new applicants, must attend the class and reapply for a license.
The new requirement kicks in Jan. 1, but city officials hope people won't wait until the last minute. Early completion of the requirements is encouraged.
City of Boulder residents will also have to have a current dog license, while out-of-city residents will need to provide proof of current rabies vaccination. There are annual fees for each dog and for each person who plans to walk the dog on open space.
The program, started in 2006, allows people whose dogs are under voice and sight control to walk their dogs off leash on designated trails.
The new education requirement is intended to make sure participants understand the rules and whether their dog can follow the rules.
To sign up for classes, go to bit.ly/1vttp5t and select "Dog: Voice and Sight" from the categories on the left side.
