How Dogs and Cats Cool Themselves: Hot Weather Can Become Dangerous for Pets

When it gets hot and humid, people can cool off by sweating, finding shade, drinking water, or going inside. Dogs and cats, though, do not cool down the same way. Their bodies have fewer ways to release heat, so they can overheat more quickly than many owners expect.

At Cliffdale Animal Hospital, we want you to know how dogs and cats cool themselves, why summer heat can be risky, and what signs mean your pet may need a vet.

Dogs Cool Themselves Primarily by Panting

Dogs get rid of most extra body heat by panting. When a dog pants, moisture leaves the tongue, mouth, and upper airways, which helps cool them down. This is normal after exercise, excitement, or being outside in warm weather.

But panting does not always work well. If the air is very hot or humid, moisture evaporates more slowly. A dog may keep panting but still struggle to cool down. This is why heatstroke can happen fast, especially after playing outside, going for walks, car rides, or being in the sun.

Dogs also try to cool off by finding shade, lying on cool spots, moving less, or drinking more water. If these things do not help, overheating can become an emergency.

Cats Have Their Own Cooling Behaviors

Cats are usually more subtle than dogs when they feel too warm. Instead of panting a lot, cats may look for cool tile, shaded rooms, sinks, bathtubs, or other cool places. They might groom themselves more, since saliva on their fur can help cool them as it dries. Cats may also slow down and rest more.

Cats do not pant as often as dogs. If your cat is panting, breathing with an open mouth, seems weak, or looks upset, take it seriously. Cats can overheat even indoors, especially in rooms without good airflow, air conditioning, or cool places to rest.

Why Heat and Humidity Are a Risk

High temperatures are dangerous, and humidity can make things worse. When the air is humid, moisture does not evaporate as well. For pets that rely on panting or evaporation to cool off, this makes it much harder to stay cool.

Pets are at higher risk during hot walks, outdoor events, car rides, trips to the beach, camping, power outages, or even just being in a backyard without shade. Closed spaces like parked cars, garages, sunrooms, and rooms without good airflow can become dangerous very fast.

Some dogs and cats are more at risk. Older pets, overweight pets, very young animals, flat-faced breeds, pets with heart or breathing problems, and those with thick coats may have a harder time handling heat.

Signs Your Pet May Be Overheating

Knowing the signs can help you act fast. Watch for these signs of overheating or heatstroke:

• Excessive panting
• Heavy drooling
• Bright red or dark red gums
• Weakness or lethargy
• Vomiting or diarrhea
• Trouble breathing
• Confusion or disorientation
• Collapse
• Seizures

In cats, warning signs can also include open-mouth breathing, hiding in strange places, restlessness, weakness, or extreme tiredness.

Heatstroke is a medical emergency. If your pet is showing concerning signs, move them to a cooler area and contact a veterinarian immediately.

What to Do If You Think Your Pet Is Overheating

If you suspect your pet is overheating, act quickly but carefully. Move your pet out of the heat and into a cool, shaded, or air-conditioned area. Offer water if your pet is alert and able to drink. You can begin cooling with cool—not ice-cold—water and use airflow from a fan if available.

Do not place your pet in an ice bath or use extreme cold, as cooling too quickly can create additional problems. Even if your pet seems to improve, a veterinarian should still evaluate them. Heatstroke can cause internal complications that are not always visible right away.

Call Cliffdale Animal Hospital or an emergency veterinary clinic for guidance as soon as possible.

How to Help Prevent Heat-Related Emergencies

Prevention is the safest approach. During warm weather, walk dogs early in the morning or later in the evening when temperatures are cooler. Avoid strenuous play during the hottest part of the day. Always provide fresh water and access to shade. Never leave pets in parked cars, even for a short time.

For cats, make sure they have access to cool indoor spaces, fresh water, and good airflow. If your cat enjoys screened porches or sunny windows, monitor the temperature carefully and make sure they can move away from the heat.

Also remember that pavement, sidewalks, sand, and asphalt can become very hot and may burn paw pads. If the ground feels too hot for your hand, it is too hot for your pet’s paws.

When to Contact Cliffdale Animal Hospital

If your pet is panting excessively, acting weak, vomiting, collapsing, breathing abnormally, or does not seem right after heat exposure, contact a veterinarian right away. It is always better to call early than to wait and see if symptoms worsen.
