As the weather heats up, it is important to know that dogs are at risk of heat stroke, a potentially life-threatening condition. Heat stroke can occur when a dog’s body temperature rises above normal levels (100.5-102.5°F = 38.0-39.2 °C), and can quickly become a medical emergency if not treated promptly.

So, what is a heat stroke, and how can you keep your furry friend safe in the heat?

What is Heat Stroke in Dogs?

Heat stroke can occur when a dog’s body temperature rises above normal levels:

  • [100.5-102.5] °F ~ [38-39.2]°C (normal body temperature in dogs)
  • [103.1-104.9] °F ~ [39.5-40.5]°C (Heat exhaustion)
  • >107°F ~ >41.5°C (Heatstroke)

which can lead to life-threatening complications if not treated quickly. The signs of heat stroke in dogs can vary, but common symptoms include:

  • Heavy panting;
  • Rapid heartbeat;
  • Excessive drooling;
  • Bright red tongue and gums;
  • Weakness or collapse;
  • Vomiting or diarrhea;
  • Seizures or tremors;
  • Unconsciousness.

In more serious cases heatstroke can cause:

  • Coma;
  • Kidney failure;
  • Brain damage;
  • Death.

Why Do Dogs Get Heat Stroke?

Unlike humans, dogs’ skins lack sweat glands to help them regulate their body temperature, they only have a few of them in their paws and around their noses which are not sufficient to help cool their bodies.

Also, the long thick hairy coats can predispose dogs to heat stroke along with several other factors, such as :

  • Being left in a car on a hot day,
  • Staying outside in hot weather without access to shade or water,
  • Exercising during the hottest part of the day,
  • Obesity,
  • Hypothyroidism, or
  • Having any other medical condition that affects their ability to regulate body temperature.

How Can You Prevent Heat Stroke in Dogs?

Fortunately, you can take steps to prevent heat stroke in your dog. Never leave your dog in a parked car, provide them with access to shade and plenty of water, avoid exercising your dog during the hottest part of the day, and invest in a cooling mat or vest. If you have a brachycephalic breed, such as a pug or bulldog, be extra cautious in hot weather.

Another way to help prevent heat stroke in dogs is to be mindful of the surfaces they walk on during hot weather. Asphalt, concrete, sand, and other surfaces can become very hot in the sun and can burn your dog’s paws, which can lead to discomfort and even heat stroke. To avoid this, try to walk your dog in grassy areas or use protective boots or paw pads.

It’s also important to be aware of your dog’s behavior during hot weather. Some dogs may be more active and playful than usual, which can increase their risk of heat stroke. Be sure to monitor your dog’s behavior and limit his activity if necessary.

Why Is Heat Stroke Dangerous for Dogs?

Heat stroke is dangerous for dogs because it can quickly lead to serious health complications and even death if not treated promptly. When a dog’s body temperature rises above normal levels, his organs can start to fail, which can cause serious damage to his body. Additionally, heat stroke can lead to dehydration, which can further exacerbate the problem.

Understanding how to prevent and recognize heat stroke in dogs is crucial for keeping your furry friend safe and healthy during the summer months. By taking the necessary precautions and seeking veterinary care promptly if needed, you can help ensure that your dog stays cool, comfortable, and healthy all summer long.

What Should You Do If You Suspect Your Dog Has a Heat Stroke?

If you suspect your dog has heat stroke, here are some actionable measures you need to do:

  • Act quickly;
  • Move him to a cool, well-ventilated, and shaded area;
  • Offer him cool water to drink;

You can also use cool water to wet their paws, belly, and ears to help bring down their body temperature. But don’t use ice-cold water as this can make your dog’s veins constrict and prevent his body from releasing heat.

However, it’s crucial to note that this is not a substitute for veterinary care. Heat stroke can cause severe complications, such as kidney failure or respiratory distress, and may require hospitalization for treatment.

If you suspect your dog has heat stroke, seek veterinary care immediately.

What will the vet do to treat my dog’s heat stroke?

If your dog is experiencing heat stroke, it is important to seek veterinary care immediately. The veterinarian will perform a physical examination and may take blood tests to check for organ damage. They will also likely administer intravenous fluids to help rehydrate your dog and lower their body temperature.

In severe cases, your dog may require hospitalization for additional treatment, such as :

  • Oxygen therapy,
  • Medications to control seizures, or
  • Supportive care for complications (i.e. kidney failure or respiratory distress).

It is important to note that the sooner your dog receives medical attention, the better their chances of full recovery. On the contrary, any delay in treatment can result in serious or even fatal complications.

So if you suspect your dog is experiencing heat stroke, do not hesitate to seek veterinary care immediately.

Can a dog recover from heat stroke?

Yes, a dog can recover from heat stroke if it is treated promptly and appropriately. However, the chances of recovery depend on the severity of the condition and how quickly it is recognized and treated.

In mild cases, the dog may recover quickly with no lasting effects. In more severe cases, the dog may require hospitalization and supportive care such as intravenous fluids, oxygen therapy, and medications to manage symptoms and prevent complications.

In some cases, the dog may experience long-term effects such as organ damage or neurological deficits. Therefore, it is essential to take preventive measures and seek veterinary care immediately if you suspect your dog is experiencing heat stroke.

How long can heat stroke last in dogs?

The duration of heat stroke in dogs can vary depending on the severity of the condition and how quickly it is treated. Mild cases of heat stroke may resolve within a few hours, while more severe cases can last for several days or even weeks.

In some cases, dogs may experience long-term complications as a result of heat strokes, such as kidney damage or neurological problems.

What dog breeds are more prone to get heat stroke?

Certain dog breeds are predisposed to get heat stroke due to their anatomy, which can affect their ability to regulate body temperature:

Brachycephalic breeds, such as Bulldogs, Pugs, Boston Terriers, and Boxers, are particularly vulnerable to heat stroke because of their short snouts and narrowed airways. These breeds may also have difficulty panting, which is the primary way dogs regulate their body temperature.

Other breeds that are at an increased risk of heat stroke include dogs with thick coats or heavy musculature, such as St. Bernards, Newfoundlands, and Mastiffs. However, any dog can develop heat stroke if exposed to high temperatures for prolonged periods or subjected to intense physical activity in hot conditions.

While light-colored dogs are not necessarily more prone to heat stroke than darker-colored dogs, they may be more susceptible to sunburn and skin damage.

Dogs with lighter fur and skin may be at a higher risk of developing skin cancer and other skin-related health issues if they are not protected from the sun. It’s important to provide shade and limit sun exposure for all dogs, regardless of their fur color.

What not to do if your dog has heat stroke?

If your dog has heat stroke, there are certain things you should avoid doing, as they can make the situation worse. Here are some things to avoid:

  1. Do not give your dog ice-cold water or ice cubes to drink. This can cause their blood vessels to constrict, which can trap heat in their body and prevent heat from escaping.
  2. Do not use ice packs or ice baths to cool your dog down. Similarly to giving your dog ice-cold water, this can cause their blood vessels to constrict and prevent heat from escaping, which can worsen the situation.
  3. Do not force your dog to exercise or move around too much. This can increase their body temperature and make it harder for them to recover.
  4. Do not wait to seek veterinary care. Heat stroke can be a medical emergency and requires prompt treatment to prevent serious complications or death.

By avoiding these actions and seeking veterinary care as soon as possible, you can help give your dog the best chance at recovery from heat stroke.


Heat stroke can be a serious and potentially life-threatening condition for dogs. By taking steps to prevent it and recognizing the signs, you can help keep your furry friend safe and healthy during the hot summer months. Remember to always be mindful of your pet’s well-being and take immediate action if you suspect they are experiencing heat stroke.
