Heatstroke is a serious and life-threatening condition that can affect dogs. It occurs when a dog's internal body temperature rises above 105°F and can have fatal consequences if not addressed promptly. Dogs are susceptible to heatstroke due to their limited ability to cool down, primarily through panting and blood vessel expansion. Certain factors, such as high humidity, lack of shade, inadequate water access, and confinement in cars or closed spaces, can put dogs at higher risk. Recognizing the early signs of heatstroke, such as heavy panting, rapid breathing, and excessive drooling, is crucial to prevent severe complications or even death. Immediate action to lower the dog's body temperature and seek veterinary care is essential for a positive outcome.

Heatstroke can occur in minutes, even when the temperature doesn't seem hot
Heatstroke in dogs is a serious and life-threatening condition. Dogs are not efficient at cooling off and dissipating body heat. They cool themselves primarily by panting and blood vessel expansion. Therefore, they are at a higher risk of overheating.
The risk of heatstroke depends on several factors, including the dog's activity level, age, overall health, thickness of their fur, and shape of their head. Brachycephalic ("flat-faced") breeds, such as Pugs and Boxers, are prone to overheating due to their breathing problems. Puppies under six months, older dogs, and overweight dogs are also at a higher risk.
Additionally, environmental factors such as high humidity, lack of shade, inadequate ventilation, and restricted access to water can contribute to heatstroke. Dogs left in closed vehicles, homes, or crates without proper ventilation and water are at a high risk of heatstroke.
The signs of heatstroke include heavy panting, rapid breathing, excessive drooling, dry mucous membranes, bright red gums and tongue, hot skin, and an increased heart rate. As heatstroke progresses, dogs may exhibit signs of shock, pale mucous membranes, a rapid heart rate, a drop in blood pressure, dehydration, muscle tremors, lethargy, and collapse.
To prevent heatstroke, it is crucial to keep dogs cool, hydrated, and well-ventilated. Provide ample shade, water, and rest breaks, especially during hot weather. Avoid exercising them during the hottest times of the day, and never leave them unattended in parked cars.
If you suspect heatstroke, immediately remove the dog from the hot environment and gradually lower their body temperature using cool water and fans. Do not use ice or cold water, as it can constrict blood vessels and hinder cooling. Seek veterinary attention as soon as possible, as heatstroke can lead to severe complications and even death.

Dogs cool themselves by panting and blood vessel expansion
Dogs have three main ways to cool themselves: panting, sweating, and blood vessel expansion. Panting is the most effective way for dogs to cool down. When a dog pants, moisture is evaporated from their nose, tongue, and lungs, and the air passing across the moist tissue helps to cool them down. However, if the air being taken in during panting is already warm, it is ineffective at cooling the dog down.
Dogs also cool themselves by sweating through their paw pads, which have two types of sweat glands: merocrine glands and apocrine glands. Merocrine glands are similar to human sweat glands and are activated when a dog gets hot, helping to cool them down through evaporation. Apocrine glands, on the other hand, release pheromones to cool off the dog and are located all over the dog's body.
Finally, dogs rely on blood vessel expansion, or vasodilation, to help cool themselves. Vasodilation is when the blood vessels expand and bring hot blood closer to the surface of the skin, enabling the blood to be cooled down before it returns to the dog's heart. This helps regulate the dog's internal body temperature.

Heatstroke can cause lethargy, weakness, collapse, seizure, coma, brain damage, and death
Heatstroke in dogs is a life-threatening condition that can cause lethargy, weakness, collapse, seizure, coma, brain damage, and death. It is the result of a dog's inability to cool their body down, and it can occur very quickly, even in under an hour.
Heatstroke can be caused by a dog being left in a car, even on a relatively cool day, or by a dog exercising on a hot, humid day. Brachycephalic dogs (those with short noses and flattened faces, such as Pugs or Boxers) are at a higher risk, as are dogs with certain medical conditions or on certain medications.
The first sign of heatstroke in a dog is typically heat cramps, characterised by muscle spasms, and this is often related to dehydration and electrolyte imbalance. As the dog continues to be exposed to heat, they may develop heat exhaustion, which is characterised by fatigue and weakness, and possibly vomiting and diarrhoea.
As the dog's temperature increases, they may experience disorientation, seizures, and multiple organ dysfunction. Heatstroke results in damage to the tissues of the body, which leads to decreased blood flow to the organs and can ultimately cause organ damage and failure.
If you suspect a dog is experiencing heatstroke, it is important to act quickly. Move the dog to a cool or shaded area and wet their body with room-temperature water (never use ice). Then, take them to a vet as soon as possible.

Heatstroke can be prevented by keeping dogs in appropriate environmental conditions
Heatstroke is a life-threatening condition that occurs when a dog's body temperature rises too high and cannot be cooled effectively. This can cause severe damage to body organs and can result in death.
- Avoid Excessive Heat Exposure: Keep dogs in cool and well-ventilated areas, especially during hot weather. Provide access to shade and ensure proper air circulation to prevent overheating.
- Maintain a Comfortable Temperature: Maintain a comfortable ambient temperature for dogs, especially in enclosed spaces such as cars, dog houses, or crates. Avoid leaving dogs in parked cars, as temperatures can rise rapidly, even on mild days.
- Provide Adequate Hydration: Ensure dogs have constant access to fresh, cool water to prevent dehydration. This is crucial during hot weather or after exercise.
- Regulate Physical Activity: Avoid strenuous exercise or vigorous physical activities during hot and humid weather. Adjust the intensity and duration of exercise according to the dog's fitness level, breed, and age. Provide frequent breaks and opportunities to cool down.
- Consider the Dog's Characteristics: Some dogs are more prone to heatstroke due to their physical attributes or health conditions. Brachycephalic breeds (short-muzzle or flat-faced dogs) such as Pugs and Bulldogs, as well as dogs with thick or heavy coats, are more susceptible to overheating. Additionally, older, overweight, or young dogs may have a higher risk of heatstroke.
- Provide Proper Grooming: Proper grooming can help prevent heatstroke. Ensure your dog's coat is well-groomed and not excessively thick, especially during hot seasons. This can aid in effective heat dissipation.
- Monitor for Early Signs: Be vigilant for early warning signs of heatstroke, such as heavy panting, drooling, lethargy, disorientation, or abnormal gum colour. If you notice any of these symptoms, take immediate action to cool your dog down and seek veterinary advice if necessary.
- Provide Adequate Ventilation: Ensure adequate ventilation in enclosed spaces where dogs are kept, such as dog houses or crates. Proper ventilation helps regulate temperature and prevents heat buildup.
- Avoid Restrictive Clothing or Muzzles: Avoid dressing dogs in restrictive clothing that may trap heat. Additionally, avoid muzzling dogs, as it restricts their ability to pant and regulate body temperature.
- Provide Access to Cool Surfaces: Provide dogs with access to cool surfaces, such as tiled floors or cooling pads, especially during hot weather. This can help them regulate their body temperature more effectively.
- Be Mindful of Medications: Some medications can increase the risk of heatstroke in dogs. Consult your veterinarian to understand the potential side effects of any medications your dog is taking, and take extra precautions during hot weather.
