California’s heat waves are getting hotter, longer and more frequent — and while you may be able to head indoors or crank up the A/C, your dog relies on you to stay safe. Unlike humans, dogs don’t sweat efficiently and can overheat quickly, making extreme heat a serious health risk.
Whether you’re exploring a dog-friendly trail, hanging out at home or road-tripping across the Golden State, here’s how to keep your pup cool, comfortable and protected when temperatures soar.
Rethink your daily routine
During a heat wave, timing is everything. Plan walks, hikes and outdoor play for early morning or after sunset, when temperatures are significantly lower.
Midday outings can be dangerous, especially once temperatures climb into the 80s and 90s. Even if the air feels tolerable, surfaces like asphalt and sand can become scorching. Pavement can heat up far beyond the air temperature and burn sensitive paw pads in seconds.
A simple rule: if you can’t comfortably hold your hand on the pavement for several seconds, it’s too hot for your dog.
Hydration is non-negotiable
Always provide unlimited access to fresh, cool water — indoors and outdoors.
If you’re out exploring, bring a portable bowl and offer frequent water breaks. Dogs can become dehydrated quickly in high heat, especially during activity.
At home, consider adding extra water stations and even offering frozen treats or ice cubes as enrichment. Keeping hydration levels up is one of the most effective ways to prevent heat-related illness.
Create shade and cooling zones
Shade is essential, whether you’re at a campsite, beach or backyard. Dogs should never be left in direct sun without relief.
Outdoors, use umbrellas, trees or pop-up shade structures. Indoors, aim for well-ventilated spaces with fans or air conditioning. During extreme heat, it’s often safest to keep pets inside where temperatures are controlled.
Cooling strategies can be simple and fun: a kiddie pool, sprinkler or damp towel can help lower your dog’s body temperature safely.
Never leave your dog in a car
This can’t be said enough. Even on a mild day, the temperature inside a parked car can rise rapidly to deadly levels — and cracking the windows doesn’t help.
If you’re running errands, leave your dog at home. California heat waves turn vehicles into ovens within minutes.
Adjust exercise and expectations
Your dog doesn’t need the same level of exercise during extreme heat. Swap long hikes for shorter walks, indoor games or mental stimulation like puzzle toys.
Dogs cool themselves primarily by panting, which becomes less effective in high temperatures. Overexertion can quickly lead to heat exhaustion or heatstroke.
Certain dogs are especially vulnerable, including flat-faced breeds (like bulldogs and pugs), seniors, puppies and dogs with thick coats or underlying health issues. Extra caution is essential for these pups.
Protect those paws
Hot pavement is one of the most overlooked dangers. Asphalt and concrete can retain heat and reach temperatures high enough to cause burns.
Stick to grassy or shaded trails when possible. If you must walk on hot surfaces, consider protective booties — or skip the walk altogether.
Know the signs of heatstroke
Heatstroke is a medical emergency. Watch for excessive panting, drooling, vomiting, lethargy or disorientation.
If you notice these symptoms, move your dog to a cool area immediately, offer small amounts of water and contact a veterinarian right away.
California’s outdoor lifestyle doesn’t have to stop when temperatures spike — it just needs a seasonal adjustment. With a little planning and awareness, you and your dog can still enjoy summer safely, from coastal escapes to mountain retreats.
Because during a heat wave, the best adventure is a safe one.
