What Is Dog Overheating?

Dog overheating happens when your dog’s body can’t cool itself fast enough. This can quickly lead to serious health problems, including heat exhaustion or even heat stroke.

Causes of Overheating in Dogs

Most dogs overheat during hot weather, especially if they stay outside for long periods. It can also happen if your dog plays too hard, is left in a car, or doesn’t have access to water and shade.

Dogs with short noses like Bulldogs, Pugs, or Shih Tzus are at higher risk because their airways make it harder to cool down. Overweight dogs, puppies, and older dogs also struggle more in warm temperatures.

Hot pavement, high humidity, and poor ventilation make overheating worse. Even indoor spaces can become dangerous if they get stuffy or too warm.

Signs that your dog may be overheating include excessive panting, drooling, and bright red gums. You can read more about these symptoms and prevention tips on the AKC guide.

The Science Behind Overheating

Dogs cool themselves mostly by panting, not by sweating like humans. When panting isn’t enough, their body temperature rises quickly.

If your dog’s internal temperature goes above 104°F, it’s considered overheating. Normal body temperature for a dog is between 101°F and 102.5°F.

Heat exhaustion begins as the temperature climbs higher. If it reaches 108°F or more, seizures or organ damage can happen, as outlined in this article on dog overheating.

High humidity makes it harder for dogs to lower their temperature through panting. When the cooling system fails, blood vessels expand, gums turn red, and your dog can go into shock.

Warning Signs of Overheating in Dogs

Dogs can overheat quickly, especially in hot weather or after heavy exercise. It’s important to notice the warning signs early to keep your dog safe and healthy.

Physical Symptoms to Watch For

When your dog gets too hot, you may notice several changes in their body. One of the clearest is excessive panting.

Unlike normal panting, this will seem frantic and hard for your dog to control. You might also see drooling or extreme salivation that’s thicker than usual.

Look at your dog’s gums, tongue, and ears. If they turn a bright red color, this is a warning sign that your dog is overheating.

Some dogs will have trouble breathing, with rapid or labored breaths. Other symptoms to watch for include vomiting, diarrhea, or soft stool.

Your dog’s heartbeat may also become fast or irregular. For a full list of physical symptoms, you can visit this detailed guide on overheating signs.

Behavioral Changes in Overheated Dogs

Alongside physical signs, overheating also causes clear changes in your dog’s behavior. An overheated dog will often slow down suddenly, even during activities they usually enjoy.

You might see them stop walking or running and sit down unexpectedly. Lethargy is common—your dog may seem unusually tired or weak.

Confusion and disorientation can happen too. Your pet might wander around, bump into things, or not respond to their name.

Some dogs become anxious or restless, pacing or whining for no clear reason. Others may collapse or lie down and refuse to get up.

Prevention Tips for Dog Overheating

Dogs can quickly get overheated when the temperature climbs. Simple steps like finding shade, giving water, and planning activities help keep your pet safe and comfortable.

Keeping Dogs Cool in Hot Weather

Always give your dog a shady place when outside. Direct sun heats up quickly and can make your dog sick.

Use trees, canopies, or umbrellas to block out the sun. If you don’t have natural shade, using a portable canopy or even a large towel works in a pinch.

Limit the amount of time your dog stays outside on very hot days. Try setting up a kiddie pool with cool water, or turn on a hose briefly for them to splash in.

This helps lower body heat and gives a fun break. Never leave your dog in a parked car—even for a few minutes.

The temperature inside a car climbs fast and is dangerous, even if the windows are cracked. For more detailed ideas, read tips on how to keep your dog cool in the summer heat.

Hydration and Access to Water

Make sure your dog always has fresh, cool water. Bring a water bottle and portable bowl whenever you go for walks or trips.

Refill the bowl often, especially on hot days, since water warms up quickly outside. Watch for signs your dog is thirsty, like heavy panting or drooling, and offer water right away.

At home, place several water bowls in different spots so your dog can drink easily throughout the day. Splashing or wiping cool tap water on your dog’s belly, paws, and neck also helps their body cool down.

Exercise Precautions

Only walk or play with your dog in the early morning or late evening when it is cooler. If you must go out during the day, keep activity short and stick to shady paths or grassy areas.

Hot pavement and sand can burn your dog’s paws, so touch the ground first with your hand. If it’s too hot for you, it’s too hot for your dog.

Carry water and take breaks every 10-15 minutes. If your dog starts panting hard, slowing down, or acting tired, stop right away and move to a cooler area.

Never push them to keep going. Get more advice on exercising your dog safely when temperatures rise.

First Aid and Emergency Steps for Overheating

Quick action is important when your dog shows signs of overheating. Knowing what to do can protect your dog from serious harm.

Immediate Actions to Take

Move your dog to a shaded or cool spot right away. Shade helps stop their body temperature from rising further.

Pour cool (not cold) water over their body, making sure to get their belly and paws wet. Using very cold water or ice can cause shock, so stick with cool tap water.

You can also use wet towels on your dog’s body, but make sure you change them often so they stay cool. Encourage your dog to drink small amounts of water.

Avoid forcing them if they refuse, as this could cause choking. Check your dog’s breathing and look for signs like fast panting, drooling, weakness, or confusion.

If you have a thermometer, check their temperature every few minutes. Here’s a step-by-step guide to first aid for heatstroke in dogs.

When to Seek Veterinary Help

If your dog’s condition does not improve after a few minutes of cooling, get them to a vet quickly. Watch for symptoms like vomiting, diarrhea, seizures, or collapse.

Even if your dog seems better, heatstroke can cause problems that show up later, so a vet visit is still needed. Signs that mean you should seek emergency help include acting confused, not responding to your voice, or losing consciousness.

Prompt medical care can save your dog’s life. If you notice your dog’s temperature stays above 104°F (40°C), or if their symptoms get worse, don’t wait.

Call your vet or an emergency clinic right away. These are clear signs that professional help is needed to prevent serious health risks.

Recognizing At-Risk Breeds and Dogs

Some dogs are much more likely than others to overheat because of their breed or certain health problems. Knowing if your dog falls into these groups can help you keep them safer in warm weather.

Breeds Prone to Overheating

Certain dog breeds are just more likely to get heatstroke, mainly because of how their bodies are built. Dogs with short, flat faces—called brachycephalic breeds, like pugs, French bulldogs, and English bulldogs—often can’t breathe well, especially when it’s hot out.

Bigger dogs, especially those over 110 pounds, also face higher risks. Their bodies just make more heat and can’t cool off fast enough.

Here’s a quick list of breeds that tend to overheat more easily:

• Pugs
• French Bulldogs
• English Bulldogs
• Boxers
• Boston Terriers
• Shih Tzus
• Chow Chows

Flat-faced breeds have about double the chance of getting heatstroke compared to other dogs. Dogs with thick coats, like Chow Chows, can also get too warm pretty fast when it heats up outside.

Health Conditions That Increase Risk

Some health problems make your dog more likely to overheat, even if they’re not a high-risk breed. Heart disease, breathing issues, and obesity are big factors.

Dogs with heart or lung problems just can’t cool down as well because their bodies work harder to get oxygen and keep a normal temperature. Older dogs and puppies are at higher risk too, since their bodies don’t handle stress as well.

Overweight dogs have a tougher time losing heat, so their temperature can climb faster. Medications for anxiety or other conditions might also mess with your dog’s ability to stay cool.

If your dog deals with any of these issues, you’ll need to be extra careful during hot days. Always keep an eye out for overheating and do what you can to keep your pet cool. For more on health risks, check out heat exhaustion in dogs.
