Heat Stroke in Dogs: What Every Pet Owner Needs to Know

A bulldog sits comfortably beneath a chair, looking relaxed and content in its shaded spot.

As the warmer months approach, it’s essential for pet owners to be aware of the dangers of heat stroke in dogs. Every summer, veterinary clinics see a rise in cases where dogs are brought in suffering from this potentially fatal condition. Understanding the signs, risks, and prevention strategies can help you keep your canine companion safe and comfortable.

What Is Heat Stroke?

Heat stroke, or hyperthermia, occurs when a dog’s body temperature rises above a safe level and cannot cool down naturally. Unlike humans, dogs don’t sweat through their skin—they rely mainly on panting to regulate their body temperature. When the heat becomes too intense or they’re unable to cool down quickly enough, their internal organs can begin to shut down, sometimes with tragic consequences.

Common Causes

Heat stroke in dogs often results from:

  • Being left in a hot car, even for a few minutes
  • Excessive exercise in hot weather
  • Lack of shade and water during outdoor activities
  • Flat-faced breeds (like Pugs and Bulldogs) being exposed to high temperatures
  • Underlying health conditions that affect breathing or circulation

Recognising the Signs

Early recognition is crucial. Symptoms of heat stroke include:

  • Excessive panting or difficulty breathing
  • Bright red or pale gums
  • Lethargy or weakness
  • Drooling or vomiting
  • Confusion or uncoordinated movements
  • Collapse or seizures in severe cases

If you notice any of these signs, act quickly. Heat stroke can escalate in a matter of minutes.

Immediate Action

If you suspect your dog is suffering from heat stroke:

  1. Move them to a cooler area immediately—shade or an air-conditioned room.
  2. Cool them down gradually by applying cool (not cold) water to their body, especially the belly, paws, and underarms. Try to avoid the face.
  3. Offer small amounts of cool water to drink, but don’t force them.
  4. Seek veterinary care right away, even if your dog seems to recover. Internal damage may not be immediately obvious.

Prevention Tips

Preventing heat stroke is far easier than treating it:

  • Never leave your dog in a parked car, even with the windows open.
  • Walk your dog during the cooler parts of the day, such as early morning or evening.
  • Provide plenty of fresh water and shade when outdoors.
  • Avoid strenuous exercise such as chasing balls in hot weather.
  • Be extra cautious with flat-faced breeds, older dogs, or those with health issues - sometimes it’s better to avoid walking them at all in the heat.

When in Doubt, Reach Out

If you’re ever uncertain whether your dog is too hot or not coping well with the weather, it’s always best to contact Tribe Vets, or our partners at Vidivet. Heat stroke is a true emergency, but with the right knowledge and prompt action, it is entirely preventable.

Stay cool, stay safe, and enjoy the summer with your furry friends!
