What are Colorado's Dog Licensing Laws?

In Colorado, getting a license for your dog is usually required within 30 days of the dog entering the state. While not all areas require licensing, most do. In Mesa County, it is required that a dog owner license the animal.

Licensing can be done online, in person, or by mail. While a local humane society can license a pet, your local veterinarian likely also offers this service. Dogs and Cats over four months old in Colorado are also required to have a rabies vaccination. Find out more about licensing in Mesa County, Colorado here.

What Leash Laws Exist in Colorado?

Colorado does not have a state-wide leash law on the books in 2023, but the state does require all dogs must be under control at all times. The state gives local governments the authority to create leash laws. Communities like Aspen, Colorado Springs, Denver, Golden, and Sterling prohibit dogs from running loose in town. Dogs found roaming free in these communities may be impounded, and the animal's owner is subject to fines or possible jail time.

In Mesa County, dogs are required to be on a leash no longer than 10 feet when in a park or open space unless otherwise indicated by posted signs. The city of Grand Junction has two off-leash dog parks. One is located at Canyon View Park and the other at Las Colonias Park. Rules for dogs are posted on the grounds.
