Heatstroke in Dogs: Signs, Urgent Care & Prevention Tips | Mascot Animal Hospital
As temperatures rise, heatstroke becomes one of the most dangerous summer emergencies for dogs. Unlike humans, dogs cannot cool themselves efficiently through sweating. They primarily rely on panting to regulate body temperature, making them highly vulnerable to overheating during hot and humid weather.
At Mascot Animal Hospital, we frequently treat pets suffering from heat-related illnesses. Recognizing the warning signs early and seeking immediate veterinary care can save your dog’s life.

What Is Heatstroke in Dogs?
Heatstroke occurs when a dog’s body temperature rises to dangerous levels and the body can no longer cool itself effectively. When the internal temperature exceeds 40°C (104°F), vital organs can begin to fail, leading to severe complications or even death if left untreated. Heatstroke is considered a medical emergency and requires immediate veterinary attention.
Signs and Symptoms of Heatstroke in Dogs
Heatstroke can progress rapidly and become life-threatening if not treated promptly. As a pet owner, it’s important to recognize the warning signs early. Common symptoms of heatstroke in dogs include:
- Excessive or heavy panting
- Bright red or unusually dark gums
- Rapid heart rate
- Excessive drooling
- Signs of dehydration, such as dry gums and lethargy
- Elevated body temperature (above 40°C or 104°F)
- Vomiting, sometimes with blood
- Diarrhea, which may also contain blood
- Confusion, disorientation, or difficulty walking
- Weakness or sudden collapse
- Tremors or seizures in severe cases
- Loss of consciousness and, if left untreated, death
What Causes Heatstroke in Dogs?
Heatstroke occurs when a dog’s body temperature rises faster than it can be regulated. Since dogs rely primarily on panting rather than sweating to cool themselves, they can quickly overheat in hot or humid conditions.
Common Causes of Heatstroke
Being Left in a Parked Vehicle
One of the most common causes of heatstroke is leaving a dog inside a parked car. Even when the weather feels mild, temperatures inside a vehicle can climb rapidly within minutes. Cracking the windows or leaving the air conditioning on may not provide adequate protection, making any unattended vehicle a dangerous environment for pets.
Outdoor Activity During Hot Weather
Dogs that exercise, walk, or play outdoors during peak temperatures are at increased risk of overheating. Hot pavement, direct sunlight, and high humidity can make it difficult for a dog to cool down effectively. To reduce the risk, schedule outdoor activities during the early morning or evening and ensure your pet has access to plenty of fresh drinking water.
Which Dogs Are More Vulnerable?
While any dog can develop heatstroke, some are more susceptible than others, including:
- Flat-faced breeds such as Pugs, Bulldogs, and Boxers
- Senior dogs
- Overweight or obese pets
- Dogs with heart conditions
- Pets with breathing difficulties or airway disorders
- Dogs with tracheal collapse or laryngeal paralysis
- Pets taking medications that may affect temperature regulation
Why Dogs Overheat More Easily Than Humans
Unlike humans, dogs have very few sweat glands. Their primary cooling mechanism is panting, which releases heat through moisture evaporation from the tongue and respiratory tract. During extremely hot or humid weather, this process becomes less effective, causing body temperature to rise rapidly.
What Should You Do If You Suspect Heatstroke?
If your dog is showing signs of overheating, act immediately. Move them to a cool, shaded area and contact your veterinarian without delay.
While transporting your pet:
- Use cool or room-temperature water to gently wet their body
- Place damp towels over their back and abdomen
- Keep air circulating with a fan or air conditioning if available
- Offer small amounts of water if your dog is alert and able to drink
Avoid using ice or ice-cold water, as sudden temperature changes can lead to shock and may worsen the condition.
If your dog is experiencing heavy panting, weakness, vomiting, or signs of heatstroke, don’t wait. Book an appointment with Mascot Animal Hospital for immediate veterinary attention and professional care.
Treatment for Heatstroke in Dogs
Heatstroke is a serious condition that requires immediate veterinary care. At Mascot Animal Hospital, treatment focuses on lowering your dog’s body temperature safely, preventing complications, and supporting affected organs during recovery.
How Is Heatstroke Treated?
Depending on the severity of your pet’s condition, treatment may include:
- Intravenous (IV) fluid therapy to correct dehydration and maintain circulation
- Medications to control vomiting, diarrhea, and gastrointestinal irritation
- Oxygen therapy for pets experiencing breathing difficulties
- Continuous monitoring of body temperature and vital signs
- Medications to manage seizures or neurological complications when necessary
- Specialized treatments to support heart function and organ health
- Blood tests and diagnostic monitoring to evaluate internal organ function
Our veterinary team closely monitors each patient throughout the recovery process to ensure they receive the care they need.
Heatstroke is a medical emergency that requires prompt veterinary attention. If you notice excessive panting, weakness, collapse, vomiting, or any other signs of heat-related illness, contact Mascot Animal Hospital immediately. Early intervention can significantly improve your dog’s chances of a full recovery
Recovery After Heatstroke in Dogs
A dog’s recovery from heatstroke largely depends on how quickly veterinary treatment is provided. The sooner a pet receives medical attention, the better their chances of a successful recovery.
Many dogs recover fully with prompt treatment and supportive care. However, severe heatstroke can affect vital organs such as the kidneys, liver, heart, and brain, potentially leading to long-term health complications.
Some pets may need to remain hospitalized for observation, fluid therapy, and ongoing treatment until their condition stabilizes. After returning home, rest, hydration, and following your veterinarian’s recommendations are essential for recovery.
At Mascot Animal Hospital, we may recommend follow-up visits and diagnostic testing to monitor your dog’s overall health and ensure all organ functions have returned to normal. Regular check-ups help support a smooth recovery and reduce the risk of future complications.
When to Seek Urgent Veterinary Care
Seek immediate veterinary attention if your dog shows any of the following signs of heatstroke:
- Excessive or heavy panting
- Vomiting or diarrhea
- Weakness or extreme lethargy
- Confusion or disorientation
- Difficulty walking or stumbling
- Sudden collapse
- Tremors or seizures
- Bright red gums or excessive drooling

Frequently Asked Questions
Can dogs get heatstroke on a walk?
Yes. Dogs can develop heatstroke during walks, especially in hot or humid weather. Walking on hot pavement, exercising during peak temperatures, or prolonged outdoor activity can increase the risk.
How do I cool down my dog safely?
Move your dog to a cool area, use room-temperature water to wet their body, and provide good airflow with a fan or air conditioning. Avoid using ice or very cold water, as this can cause shock and slow the cooling process.
Why is my dog panting excessively after being outside?
Excessive panting may be a sign that your dog is struggling to regulate its body temperature. If panting is accompanied by weakness, drooling, vomiting, or red gums, seek veterinary care immediately.
Can puppies get heatstroke?
Yes. Puppies are more sensitive to heat and may overheat faster than adult dogs. They should always have access to shade, water, and a cool environment during warm weather.
Are senior dogs more likely to suffer from heatstroke?
Yes. Older dogs often have reduced tolerance to heat and may have underlying health conditions that increase their risk of heat-related illnesses.
How long does it take a dog to recover from heatstroke?
Recovery time varies depending on the severity of the condition. Some dogs recover within a few days, while severe cases may require hospitalization and extended monitoring.
Can heatstroke cause permanent damage in dogs?
In severe cases, heatstroke can lead to long-term damage to the brain, kidneys, liver, or heart. Early treatment helps reduce the risk of permanent complications.
Is heatstroke more common in certain seasons?
Heatstroke is most common during the summer months, but it can occur any time temperatures and humidity levels rise significantly.
What is the difference between overheating and heatstroke?
Overheating is the early stage of heat stress, while heatstroke is a severe condition where the body can no longer regulate its temperature. Heatstroke requires immediate veterinary treatment.
Can dogs get heatstroke in the shade?
Yes. Even when resting in the shade, dogs can develop heatstroke if temperatures are extremely high, humidity is elevated, or ventilation is poor.
