If you’ve ever glanced over at your dog on a hot day and noticed rapid panting, a long tongue hanging out, and maybe even some drool on the floor, you’re not alone in wondering: Is my dog too hot? Many pet parents get concerned (or even a little alarmed) at heavy panting and may not know what’s normal or what requires action.

The truth is, panting is your dog’s version of sweating. Since dogs don’t regulate their temperature through their skin the way humans do, they rely on their respiratory system—taking in air quickly and evaporating moisture in their mouth and lungs—to cool down. Some panting is perfectly natural. But when the summer heat cranks up, that panting can escalate into a signal that your dog is struggling to regulate their body temperature.

Knowing how to help your dog cool down safely can make all the difference between a happy, comfortable pup—or, in worst cases, a veterinary emergency.

So, let’s talk about how to keep your dog cool in hot weather, why certain tricks work better than others, and what not to do if your pup is overheating.

Why Dogs Pant (And Why It’s So Important to Pay Attention)

Panting is your dog’s built-in cooling system. When they pant, moisture on their tongue, airway, and lungs evaporates, which lowers their core body temperature. Unlike humans, who have sweat glands all over their body, dogs only sweat through their paw pads and nose—tiny areas that aren’t nearly enough to stay cool during high heat.

Normal panting is shallow, rhythmic, and happens after exercise, excitement, or exposure to warm temperatures. But heavy, rapid, or distressed panting—especially when paired with drooling, lethargy, or trouble standing—is a warning that your dog may be overheating. That’s when immediate cooling strategies are crucial.

Smart & Safe Ways to Keep Your Dog Cool

If your dog is panting hard on a hot day, here are some techniques to provide relief and prevent overheating.

Use a Cooling Bandana or "Doggy Gator"

You can buy cooling bandanas designed for dogs, or simply dampen a lightweight bandana and tie it loosely around your dog’s neck. This targets an area where large blood vessels run close to the skin, which helps cool the blood traveling to the brain and ultimately reduces internal temperature.

Pro tip: Re-wet or swap the bandana frequently since it will dry out quickly in hot weather.

Focus on the Underside, Not the Back

A common mistake owners make is hosing down their dog’s entire body. But drenching their back and fur can trap heat if the outer coat prevents evaporation. Instead, lightly dampen their underside—the belly, chest, and inner thighs. These areas have less coat density and closer access to the skin, so evaporation works more effectively.

Running cool (not ice-cold) water over their paws and belly works wonders without shocking their system.

Shade and Airflow Are Better Than Cold Shock

Dogs don’t necessarily need cold environments to cool down—they need shaded, ventilated areas. A fan, open window, or shaded backyard spot helps panting work better by increasing airflow. This mimics how evaporation cools humans when we sweat.

Let Them Cool Down Before Ice or Frozen Treats

Here’s an important misunderstanding: giving a dog ice-cold water or frozen treats when they’re already overheated may actually cause more harm than good. The sudden temperature change can lead to stomach cramping, or worse, shock.

If your dog has just come in from a hot walk and is panting heavily, first help them cool gradually (shade, airflow, damp cloth on belly/paws). Once their breathing slows, it’s perfectly fine to provide cold water—or fun treats like ice cubes with peanut butter or chicken broth—for safe hydration.

Avoid Midday Activity

Walking your dog during the hottest part of the day (10 a.m. – 4 p.m.) not only risks overheating but also burns their paw pads on hot pavement. Follow the “hand test”: if you can’t hold your hand on the ground for seven seconds comfortably, it’s too hot for your pup to walk on. Stick to early morning or evening strolls.

Know the Signs of Heatstroke

Heatstroke in dogs develops quickly and can be deadly. Keep an eye out for:

• Excessive panting or drooling

• Bright red gums or tongue

• Staggering or inability to stand

• Vomiting or diarrhea

• Collapse or unconsciousness

If you suspect heatstroke, move your dog to a cool place, wet their underside with cool (not cold) water, and contact a veterinarian immediately.

Why Cooling Gradually Matters

When people overheat, we instinctively look for ice water or a cold shower. But dogs’ bodies respond very differently. Cooling too quickly—especially with ice or cold baths—can constrict blood vessels, trapping heat inside the body instead of releasing it.

Think of it like pouring ice water on a steaming-hot glass—it risks breaking. Dogs’ circulatory systems are similar: when they’re overheated, their blood vessels need to stay open to release heat. Sudden cold can slam them shut and prevent cooling.

That’s why tools like damp towels, airflow, and shade are more effective and safer than dunking your dog in ice water.

Helpful Extras for Summer Comfort

Beyond immediate cooling tricks, some products and adjustments can make hot weather much more bearable:

• Cooling mats: Gel or water-filled mats designed to absorb heat. Great for indoor naps.

• Kiddie pools: Dogs love lounging with paws in shallow water. Always supervise, especially if your dog isn’t a strong swimmer.

• Frozen snacks: Homemade treats like ice cubes of low-sodium chicken broth or plain yogurt. Just offer them once your pup is calm, not mid-overheating.

• Light grooming: Don’t shave your dog (fur protects against sunburn and insulates both ways), but regular brushing helps remove excess undercoat for better airflow.

The Myth of “Panting Equals Panic”

Sometimes pet parents confuse panting with stress or illness when it’s really just a heat response. Panting is your dog’s natural cooling system—it doesn’t automatically mean something is wrong. However, because overheating can escalate quickly, it’s always better to err on the side of caution.

If you understand why your dog is panting and can help them cool down efficiently, you’ll cut out the guesswork and prevent unnecessary worry—or worse, medical emergencies.

Staying Cool Together

Our dogs depend on us to manage their environment, especially since they can’t strip off layers or reach for ice water when the sun is blazing. By learning the difference between normal panting and signs of overheating—and by applying safe, gradual cooling methods—you can keep your pup safe, healthy, and comfortable all summer long.

So, when you notice your dog panting more than usual, don’t panic right away. Check their environment, guide them into shade, let them cool naturally with help from damp cloths or airflow, and always monitor for signs of real distress. With a little extra awareness, you’ll turn hot days into safe, happy ones for your four-legged friend.
