Your Pet's Safety
• Hot Sand Temperatures In summer months, extreme sand surface temperatures up to 150 degrees F can occur from late morning through late afternoon. Plan to hike on the dunes in early morning or evening in summer months. Protect your pet’s feet with socks or pet booties. Watch your pet carefully for signs of heat exhaustion. When Medano Creek is flowing, keep your pet close to the cool, wet sand for relief. Bring a water bowl to give your pet water on your hike.
• Vehicles Do not leave pets unattended in your vehicle. Summer temperatures in a vehicle can quickly soar to dangerous levels. Extreme cold temperatures in the winter can also pose a danger to your pet.
• Cactus Spines The desert grasslands surrounding the dunes contain prickly pear cactus. If you walk your pet in the grasslands, walk slowly and carefully to to avoid injury to your pet from the sharp spines. Consider carrying tweezers or pliers.
• Dangers from Wildlife Keeping your pet on a leash less than six feet long is the best protection against wildlife. Pets may not be left tied to vehicles, trees or other objects. To prevent injuries, do not allow your pet to get close to a wild animal. Deer may kick, mountain lions or bears may attack, coyotes may chase, badgers may bite, and porcupines may release quills. On rare occasions, coyotes or other animals may approach your leashed pet. Raise your arms and shout loudly; coyotes will typically run away. Please report any unusual encounters to a park ranger. Never leave pet food out in your picnic site or campsite, as it may attract wild animals.
