Every year, dog guardians leave behind thousands of pounds of dog waste on Boulder’s open space.

Each lingering “DOO” left behind creates a bad smell for everyone. It can also cause harmful impacts to water quality and native plants – along with a citation that could result in a $500 fine.

Enjoy our shared public lands with your furry friend and help keep open space clean. Bacteria, nitrogen and phosphorous in dog waste can:

  • Enter waterways and storm drains when it rains or when snowmelt runs across the path. 
  • Cause chemical changes in soil composition that can kill native plants and encourage noxious weed infestation.  
  • Deplete oxygen in water and help encourage algal blooms.

City of Boulder Open Space and Mountain Parks (OSMP) staff invite dog guardians to help them reducing these impacts and participate in the city’s “Let’s DOO It” campaign from 9 to 11 a.m., on Sunday, Aug. 8, at the Chautauqua, Sanitas, Dry Creek and Shanahan Ridge trailheads. Join us as we all “DOO” our part to help keep OSMP lands clear of dog waste and:

  • Receive some fun dog swag – including a “Let’s DOO It” bandana – for their furry friend. 
  • Take the “Let’s DOO It” pledge to BAG IT, PACK IT and CAN IT. Immediately BAG your dog’s DOO. If a waste can is not immediately within reach, PACK IT and then CAN IT in a pet waste composting or waste receptacle. 

A city ordinance requires dog guardians to immediately remove and dispose of their pet's excrement on all open space trails and in city parks. Leaving bags with dog waste on or near the trail  even temporarily – is prohibited.  

When visiting city open space trails, remember to:

  • Carry extra poop bags with you at all times.
  • Compost your dog’s poop in OSMP dog waste receptacles.
  • Carry a sealable bag with you to cut down on the smell.
