Colorado summers are made for hiking, park days, patio outings, and outdoor adventures with our pets. But Denver’s combination of high temperatures, intense sunshine, and higher elevation can create unique risks for dogs and cats. Many pet owners are surprised to learn that heat-related illnesses can develop quickly—even when temperatures don’t seem extreme. Here are some important tips to help keep your pets safe and comfortable throughout the summer.
Denver’s Dry Heat Can Be Deceptive
While Colorado’s dry climate may feel more comfortable than humid environments, pets can still overheat quickly. The thinner air at higher elevations and intense UV exposure can make outdoor activities more demanding, especially for senior pets, puppies, and brachycephalic (flat-faced) breeds. Always monitor your pet closely during outdoor activities and provide frequent breaks in the shade.
Watch the Pavement
On sunny days, sidewalks, asphalt, and trails can become much hotter than the air temperature. Pavement temperatures can easily exceed 120°F, causing painful burns to paw pads. A simple test: place the back of your hand on the pavement for seven seconds. If it’s uncomfortable for you, it’s too hot for your pet. Whenever possible, walk during the early morning or evening and choose grassy or shaded routes.
Hydration Is Essential
Denver’s dry climate increases water loss through panting and activity. Always bring water for your pet when hiking, walking, or spending time outdoors.
Signs of dehydration may include:
• Excessive panting
• Dry gums
• Lethargy
• Sunken eyes
• Reduced skin elasticity
Fresh, cool water should always be available at home and on the go.
Be Careful on Hikes and Outdoor Adventures
Colorado offers incredible trails and open spaces, but many pet emergencies occur during summer hikes.
Before heading out:
• Bring more water than you think you’ll need
• Take frequent breaks
• Avoid hiking during peak afternoon heat
• Watch for signs of fatigue or overheating
• Consider shorter routes on especially hot days
Remember that dogs often push themselves to keep up with their owners, even when they’re becoming overheated.
Never Leave Your Pet in a Vehicle
Even with Denver’s relatively mild mornings, temperatures inside a parked vehicle can rise rapidly and become deadly within minutes. Cracked windows do not provide adequate protection. If your pet cannot accompany you inside, it’s safest to leave them at home.
Know the Signs of Heatstroke
Heatstroke is a life-threatening emergency that requires immediate veterinary attention.
Watch for:
• Excessive panting
• Difficulty breathing
• Excessive drooling
• Bright red gums
• Vomiting or diarrhea
• Weakness or collapse
• Disorientation
If you suspect heatstroke, move your pet to a cool, shaded area, offer small amounts of water, and seek veterinary care immediately.
Some Pets Need Extra Protection
Certain pets are at greater risk for heat-related illness, including:
• Bulldogs, Pugs, French Bulldogs, and other flat-faced breeds
• Senior pets
• Overweight pets
• Pets with heart or respiratory disease
• Puppies and kittens
These pets should have limited outdoor activity during hot weather and close supervision whenever temperatures rise.
