The following rules apply at all times:

  • Visitors may have no more than three (3) dogs per person.
  • Dogs are not allowed in any District water areas, including streams or ponds.
  • Dogs must be on a leash 6’ long or less. Self-retracting leashes are allowed with a maximum extended length of 25 feet.
  • Do not allow dogs to harass wildlife or other visitors.
  • Bag and remove dog waste from the Preserve by packing it out. Do NOT leave bagged waste at the Preserve or outside Preserve restrooms.

Before heading out to an open space preserve with your dog, please review the Dog Access Guidelines.

  • Always carry water for your dog. No water is provided.
  • Choose a hike within the limits of your dog’s ability.
  • Restrict exercise in the heat of the day and hike in the shade whenever possible.
  • When your hike is finished, give your dog a thorough once-over for ticks and other bugs.

Heat Exhaustion

Be aware that dogs can overheat in the open space preserves, particularly on strenuous trails and warm, summer days. Symptoms of heat exhaustion include heavy panting, dry gums, weakness, confusion and inattention. The best approach is prevention:

  • Avoid hiking with your dog on hot days, especially in direct sun.
  • Bring plenty of water for yourself and your dog. No water is provided.
  • Retreat to a cool area, rest, and provide water if your dog shows symptoms.

All recreation must be consistent with the protection of the natural environment. Compliance with the rules ensures everyone using the trails has an enjoyable experience and shows respect for others and for the land. Keeping dogs on leash reduces conflicts with other users and wildlife, and protects the safety of your dog.
