The winner in 2017, Westminster Hills is still the champ. Dogs love it for its muddy canal and swimming ponds, its 420 acres of meandering trails and wide-open roaming space, its drinking fountain, and its opportunities to chase the occasional prairie dog. Their people love the shady benches, the gorgeous views of the Front Range, the hiking feel of the space, and the fact that pups usually pass out from exhaustion soon after they leave. The park is kept extra-clean by regular poop-pickup events, and abundant baggies and trash cans help, too. If Fido is a bolter, be aware that there are fenceless areas, but it's easy to avoid them if you head toward the center. Not enough of a workout? Put the leash back on and head to nearby Standley Lake.
