Dogs cannot sweat the way we do. They pant. That is their whole cooling system. When the air temperature gets close to their body temperature, panting stops working. I learned this the scary way when Gus started wobbling on a ninety-five-degree day after a walk that felt short to me.

He was fine — I got him into air conditioning and gave him water and he recovered in twenty minutes. But I spent that evening reading everything I could about heat stroke in dogs, and I have been much more careful since.

Signs Your Pet Is Overheating

Excessive panting is the first sign, but by itself it is normal. The danger signs are:

• Panting that sounds louder or harsher than usual
• Bright red or pale gums — normal gums are pink
• Thick, sticky saliva or drooling
• Wobbling, stumbling, or seeming confused
• Vomiting or diarrhea
• Collapse

If you see any of these, get the animal into shade or air conditioning immediately. Offer water but do not force it. Cool — not cold — water on the paws, belly, and ears helps bring their temperature down. Ice water can shock their system. Call a vet.

Prevention That Actually Works

The pavement test: Before walking your dog on a hot day, press the back of your hand against the pavement for seven seconds. If it is too hot for your hand, it is too hot for their paws. Walk early in the morning or after sunset instead.

Cooling mats: I bought a pressure-activated cooling mat for thirty dollars. Gus lies on it by choice now, even when the air conditioning is on. It works by absorbing body heat — no electricity, no refrigeration.

Frozen treats: Fill a Kong toy with wet dog food or peanut butter and freeze it. It keeps them occupied and cools them from the inside. I also freeze low-sodium chicken broth in ice cube trays for hot afternoons.

Water stations: Put out multiple bowls of water in different rooms. Pets drink more when water is convenient. Change the water twice a day — warm water is unappealing and grows bacteria faster.

Cats Need Cooling Too

Cats are better at finding cool spots on their own — tile floors, bathroom sinks, the gap behind the toilet. But they can still overheat. Wipe them down with a damp cloth on the ears and paw pads. Provide a cardboard box in a shady corner — cats seek out enclosed cool spaces. And brush them more in summer to remove the undercoat that traps heat.

Never Do This

Do not leave a pet in a parked car. Not even for five minutes. Not even with the windows cracked. The temperature inside a car on an eighty-degree day hits one hundred degrees in ten minutes. This is not a suggestion. It kills dogs every summer.

Also, do not shave double-coated breeds like huskies or goldens. Their undercoat actually insulates against heat as well as cold. Shaving exposes their skin to sunburn and removes their natural temperature regulation.

Gus has a cooling mat, frozen broth cubes, and walks only before eight in the morning now. He is spoiled. But he is also safe.
