Heatstroke Symptoms in Dogs & How Heatstroke Can Be Treated

Heatstroke Symptoms in Dogs & How Heatstroke Can Be Treated

Whether you live in a hot sunny climate year-round, or get just a few hot months each year, knowing the signs of heatstroke in dogs could help to save an animal's life. Our Santa Clarita veterinary team explains how to spot the signs of heatstroke in dogs and how the condition is treated.

Hyperthermia or Heatstroke

Heatstroke is defined as an increase in core body temperature caused by environmental conditions. Your dog's normal body temperature should be around 99-102.5 degrees Fahrenheit. When a dog's body temperature rises above 105, immediate veterinary care is required. Heatstroke is an extremely serious condition that can be fatal.

How Heatstroke Happens

People begin to sweat as a way to lower body temperature. Dogs can't sweat, instead, our canine companions cool their bodies by panting. If panting isn't sufficient to cool themselves down, their body temperature may continue to rise resulting in heatstroke. 

Any breed or size of dog can suffer from heatstroke but dogs with thick fur, short noses or those suffering from underlying medical conditions tend to be more susceptible to this condition.

The most common causes of heatstroke in dogs seen by our vets include:

  • Leaving a dog in a car on a hot or sunny day
  • Forgetting to provide adequate water for your pet
  • Lack of sufficient shade in pet's outdoor play area

Signs of Heatstroke in Dogs

Excessive panting is the most obvious sign of heatstroke in dogs. However, panting isn't the only symptom of heatstroke seen in dogs. Other symptoms of heatstroke that pet parents should be aware of include:

  • Drooling
  • Reddened gums
  • Vomiting
  • Diarrhea
  • Mental dullness
  • Loss of consciousness
  • Uncoordinated movement
  • Collapse

Helping a Dog With Heatstroke

Heatstroke is a serious condition and symptoms should always be treated as an emergency! Heatstroke in dogs can lead to life-threatening issues such as abnormal blood clotting, swelling of the brain, kidney failure, and intestinal bleeding. 

Seek immediate veterinary care if your dog is displaying signs of heatstroke. While traveling to the vet's office or emergency animal hospital, keep the car windows open or the air conditioner on full to help cool your pet.

If you are unable to get to a vet's office immediately, remove the dog from the hot environment straight away and allow your pup to drink as much cool water as they want without forcing them to drink. You can also help to bring your dog's body temperature down by placing a towel soaked in cool (not cold) water over them.

Veterinary Treatment for Heatstroke in Dogs

Safely reducing your dog's body temperature will be your vet's primary focus. Cool water may be poured over your dog's head, body, and feet, or cool wet cloths may be applied to those areas. In some cases rubbing alcohol may be applied to your dog's footpads in order to help dilate pores and increase perspiration. Treatment for dogs with heatstroke may also include intravenous fluids, mild sedation and low-concentration oxygen therapy.

As well as treating the immediate symptoms of heatstroke, your vet will also monitor your dog will for secondary complications such as changes in blood pressure, electrolytes abnormalities, kidney failure, development of neurologic symptoms, and abnormal clotting. 

Prevening Heatstroke in Dogs

When it comes to the health and wellbeing of your beloved pet, preventing heatstroke from ever happening is key. Prevent heatstroke in dogs by following the tips below:

    • Never leave a dog alone in a car. Even if you park in the shade and leave the windows cracked the temperature in your car could skyrocket! Studies have shown that even on cooler days, the temperature inside a car can rise by as much as 40 degrees in as little as one hour
    • Know your dog's level of heatstroke risk and take steps to be extra cautious with dogs that have an increased risk. Dog breeds with flat or 'squished' faces (aka brachycephalic) are more likely to suffer from heatstroke than dogs with longer noses. At-risk breeds include bulldogs, Boston terriers, Boxers, Cavalier King Charles spaniels, Shih Tzus and mastiffs.
    • Dogs that are obese or those that have an underlying heart condition may be particularly susceptible to heatstroke.
    • If you must leave your dog outside for long periods of time when it's hot out, be sure to provide plenty of water and shade. A baby pool for a dog left outside may help, as they can cool themselves down by jumping in! Special cooling vests for dogs are also available for dogs that spend a lot of time in the heat.
    • Working dogs can become very focused on their job and forget to rest. Enforce rest breaks for your working dog to allow your pup's body to cool down (even if they don't want to).
