McDowell Sonoran Preserve

Rattlesnakes are an important part of the Preserve ecosystem and are a protected species. The Preserve is a wild area inhabited by a variety of wild animals, which are inherently unpredictable. While you visit their natural habitat, it is important to understand these tips to assure a safe experience.

We will be resuming hikes in October.

Rules

Dogs in the Preserve are a privilege. If you bring your dog, it is your responsibility to follow the rules:

• If it is over 90 degrees at any time in your hike, it's too hot for your dog.
• Dogs must be on handheld leash, no longer than six (6) feet at all times.
• Waste must be pick up immediately and disposed of in a trash container or carried with you until you reach a trash container.
• Loose or bagged waste on the trail is prohibited.

Heat Warning for Dog Owners

Dogs do not actually sweat. They exchange heat through panting and to a minor degree, through their feet pads. Additionally, our canine friends do not tolerate high environmental temperatures as well as humans do.

Risk groups

The risk groups are much the same as humans: old, obese, suffer from medical conditions or take medicine. Certain breeds are more susceptible to heat emergencies than other breeds. These breeds with a broad, short skull: Boxers, Bulldogs, Pugs, etc.

Causes of heat emergency in dogs

• Strenuous exercise in hot, humid weather
• Elevated temperatures from atmospheric temps and hot surface contact
• Sidewalk/natural rock surface can radiate very high temps
• 90 degree atmospheric temp/ potential surface temp of 135 degrees

Warning Signs

• Begins with heavy panting/signs of difficulty breathing
• Tongue/gums appears bright red with thick saliva
• Skin elasticity (when pinched, does not snap back)
• Worsens if dog vomits, becomes unsteady, lethargic, unwilling to move (Core temp in the 104 degree range)
• Heat Stroke:
  • lips/membranes become blue/gray
  • Rapid on-set collapse, seizure, unconsciousness and death

What to do
