Understanding Heat Stroke in Dogs
Heat stroke is a serious risk for dogs, especially during warm or humid days. Knowing the warning signs and which dogs are most at risk helps you take steps to keep your pet safe.
Even short exposure to high temperatures can be dangerous.
What Is Heat Stroke?
Heat stroke in dogs happens when their body temperature rises above a safe range, usually past 40°C (104°F). Their organs start to struggle as the heat builds up.
Dogs can’t cool down by sweating like humans. They rely mostly on panting.
When panting doesn’t work, their bodies get overwhelmed by heat. Without quick action, heat stroke can lead to seizures, organ damage, internal bleeding, or even coma.

Early signs include rapid breathing, drooling, red gums, and confusion. As things get worse, exhaustion, vomiting, and collapse can follow.
Spotting these signs early gives your dog the best shot at recovery.
Why Dogs Are Susceptible
Dogs are more likely to get heat stroke than people. They don’t sweat through their skin, and their fur traps heat.
This makes it tough for them to lose extra warmth, especially in hot or humid weather. Some dogs are at higher risk.
Brachycephalic breeds like Bulldogs, Pugs, and Boxers—the short, flat-faced ones—have narrow airways that make panting less effective. Dogs with heart or lung problems and older dogs are also more vulnerable.
Heavy exercise, even on a mild day, can push some dogs toward exhaustion fast. Long-haired breeds and overweight dogs need extra care too.
Watch for changes in breathing or energy, especially if your dog is high-risk.
Common Causes of Heat Stroke in Dogs
Heat stroke often happens when dogs get stuck in hot places without enough shade or water. Cars are especially dangerous—even on a cool day, the temperature inside a parked car can skyrocket.
Check out the RSPCA’s advice for more on prevention and causes.
Some other common triggers include:
- Too much exercise in warm weather
- Direct sun exposure without breaks
- Poor ventilation in confined areas
- Lack of fresh water on hot walks
Sometimes, even a short walk at midday can be risky. Dogs can quickly become exhausted and overheated, even if they seem fine at first.
It’s always better to plan walks during cooler times of day.
Recognising Signs and Symptoms
It’s important to spot when your dog is too hot before things get worse. Knowing the early warning signs and serious symptoms means you can act fast if your dog is in danger.
Early Signs of Heat Stroke
You might first notice your dog breathing heavier than normal. Heavy panting can happen even if your dog hasn’t been running or playing.
This is often one of the most obvious signs. Excessive drooling or salivation is common too.
Your dog’s gums or tongue might look much redder than usual. They may seem extra tired or lethargic, wanting to lie down more than normal.
Other early symptoms can include mild weakness, slight wobbliness, or restlessness. If you spot any of these, move your dog to a cool place right away.

Severe Symptoms to Watch For
If your dog’s condition gets worse, the signs become more serious. Collapse or trouble standing is a big red flag.
Your dog may start vomiting, and some dogs get diarrhoea. In severe cases, there may even be blood.
Seizures or muscle tremors can show up if their temperature keeps climbing. If you don’t act, heatstroke can cause coma.
These symptoms are really dangerous and need immediate vet care. If you see severe signs, call your vet right away.

Immediate Response to Suspected Heat Stroke
If you think your dog is suffering from heat stroke, you need to act fast. Quick first aid and knowing when to get help can make a massive difference.
First Aid Steps
Move your dog straight to a shaded, cool spot. Every second counts, so don’t wait.
Take off tight collars or harnesses to help your dog breathe. Use cool water—not ice-cold or ice—to wet your dog’s body.
Pour water over their back, belly, and paws, or use a wet towel. Avoid their nose and mouth to prevent choking.
If you have a fan, use it to help cool the water on their fur. Offer small sips of cool water if they’re alert and can swallow, but never force it if they seem confused.
Watch closely for heavy panting, vomiting, confusion, or collapse. Cooling your dog before heading to the vet is important in the treatment of heatstroke.
Don’t use ice—it can actually make things worse.
When to Seek Veterinary Help
Even if your dog seems better, head to the vet right away. Heat stroke can cause serious health issues that may not show up right away, like organ damage.
Watch for trouble standing, seizures, or gums that look very red or pale. If you’re worried or your dog doesn’t improve, get urgent medical help.
Call your vet or an emergency clinic before you arrive so they’re ready. Heat stroke is a true emergency, and early treatment of heatstroke could save your dog’s life.
Trust your gut and act quickly—professional treatment is always the safest move.
Preventing Heat Stroke in Dogs
Keeping your dog safe from heat stroke takes planning, smart choices, and knowing their risks. Small changes to your routine can make a big difference as the weather heats up.
Safe Exercise and Outdoor Activities
Taking your dog outside is important, but timing really matters. Walk early in the morning or later in the evening, when it’s cooler.
Hot pavements can burn paws, and raised temperatures can quickly lead to exhaustion—or worse. Always carry water and offer it often.
Let your dog rest if they slow down, pant heavily, or seem tired. In summer, stick to shaded paths and grassy areas instead of open, sunny spots.
Try to keep play sessions short and gentle when it’s warm. Fetch and running games can get risky on hot days.
Never leave your dog in a car, even for a few minutes—the inside temperature rises unbelievably fast. For more tips, check out this guide about preventing heat stroke in dogs.
Protecting Vulnerable Breeds
Some breeds really need extra help in the heat. Brachycephalic dogs—bulldogs, pugs, boxers—have shorter noses, which makes panting and cooling down tough.
That puts them at way higher risk for heat stroke. Older dogs, puppies, and those with thick coats also struggle more.
If your dog falls into one of these groups, it’s best to keep walks short and avoid direct sun. Always keep them in cool, shaded, and well-ventilated areas.
A fan or shallow paddling pool can help. Watch closely for early signs of overheating like heavy panting, drooling, or confusion.

Long-Term Effects and Recovery
After a dog suffers from heat stroke, many owners wonder what recovery looks like and what health problems could develop. Immediate care is important, but it’s equally crucial to know what to watch for as your dog heals.
Potential Health Complications
Heat stroke can be pretty serious. It doesn’t just mess with your dog’s temperature—sometimes, it leaves a mark long after the event.
Some dogs bounce back, but others deal with lingering issues. The most common problem after heat stroke is organ damage.
The kidneys, liver, and brain can all take a hit. In really bad cases, dogs might get acute kidney injury, breathing trouble, or even neurological problems.
You might notice changes in behaviour, wobbly walking, or seizures. It’s tough to see, honestly.
We also have to keep an eye out for rhabdomyolysis, which is muscle damage that can harm the kidneys. Some dogs, unfortunately, seem more likely to get heat stroke again, even after they’ve recovered once.

Supporting Your Dog After Heat Stroke
Helping your dog recover starts with a trip to the vet. You’ll probably need to keep a close eye on their eating, drinking, and bathroom habits.
Offer lots of fresh, cool water. Make sure your dog stays in a calm, shaded spot.
If your dog takes medication, a simple schedule or checklist can help you stay on track. Watch for any changes in personality or behaviour.
Return to the vet if you notice vomiting, diarrhoea, shaking, or weakness. Skip vigorous exercise and hot places while your dog recovers.
Sticking with a daily routine can help both you and your dog feel more comfortable. For more advice, the PDSA guide on heatstroke in dogs is pretty helpful.
Frequently Asked Questions
Heat stroke in dogs is no joke—it needs fast action and real attention. You can spot the warning signs, help at home, and support your pet with the right steps.
What can you do at home to treat your dog’s mild heat stroke?
If your dog starts showing mild symptoms, move them to a cool, shady spot right away. Offer small sips of cool water—don’t push it if they’re not interested.
Lay wet towels on their body, especially on the paws, belly, and neck. Skip the ice or freezing water; cooling should be gentle, not shocking. Always call your vet, even if your dog seems better.
How can we recognise the signs of heat exhaustion versus heat stroke in our canine friends?
Heat exhaustion usually begins with heavy panting, drooling, tiredness, and bright red gums. These signs can get worse quickly.
Heat stroke is much more dangerous. You might see weakness, confusion, vomiting, muscle tremors, or even collapse.
If you spot any of these, act fast—heat stroke can cause organ damage and be life-threatening.
What’s the expected recovery time for a dog after suffering from heat stroke?
Recovery time really depends on how bad things got and how quickly you got help. Some dogs perk up in a few days, but others might need a week or longer.
Your vet will walk you through what your dog needs at home. Sometimes, ongoing checkups are needed even after leaving the clinic.
How does heat stroke in dogs differ from heat exhaustion, and why is it important to know?
Heat exhaustion is like a warning sign—the dog’s overheated but can still cool down with your help. If you don’t step in, heat exhaustion can turn into heat stroke.
Heat stroke means the body just can’t handle the heat anymore. You might see seizures, collapse, or coma. Honestly, knowing the difference can save your dog’s life.
Can dogs experience long-term effects following a heat stroke, and how can we support them through recovery?
Heat stroke can cause lasting problems—things like kidney, heart, or brain damage. Even after surviving, your dog might feel weak or tire out fast.
Keep a close watch and limit exercise for a while. Make sure they always have fresh water, a cool place to rest, and follow your vet’s advice to help them heal.
What should you look out for in your dog in the days following a suspected heat stroke?
Keep an eye out for tiredness or weakness. Vomiting, diarrhoea, or a wobbly walk are red flags too.
Notice any changes in your dog’s behaviour. If your dog stops eating or just seems off, it’s time to call your vet.
Sometimes problems pop up even after your dog seems better. It’s honestly better to be safe than sorry, so stay alert.
