As we approach summer and the temperatures rise, dog owners must stay vigilant. Compared to humans, dogs are much less effective at heat regulation, putting them at a much higher risk of serious and sometimes fatal heatstroke.

In this blog, you will learn about preventing heatstroke in dogs, how to recognise its warning signs, and what to do in times of emergency. By being prepared and knowledgeable, you can ensure your furry friend stays safe and comfortable even on the hottest days.

What is Heatstroke in Dogs?

Heatstroke, also known as hyperthermia, occurs when a dog’s body temperature reaches above normal range (39°C). This occurs when natural cooling mechanisms like panting and sweating through their paws and nose are not enough.

Common Causes and Risk Factors

Heatstroke often occurs due to a combination of environmental factors and physical activity. Common examples include:

Hot Environments: When left in a car or area without adequate ventilation, dogs can overheat within minutes, even if windows are left slightly open.

Strenuous Exercise: Physical activity in high temperatures, especially if they are not acclimatised to the heat. Dogs will often obsessively chase a ball or toy that is thrown for them and they don’t always listen to their body. You need to hold them back, and not encourage this behavior. It is important to recognise that strenuous exercise in extreme heat is not appropriate.

Inadequate Shade and Water: A lack of access to cool and shady areas with fresh water.

Why is Heatstroke in Dogs So Serious

Dogs primarily regulate body temperature through panting. This process is far less efficient compared to humans, especially in humid weather. Heatstroke can cause serious complications, including :

Damage to organs
Impact brain function
Death

For these reasons, preventing your dog from getting heatstroke is essential!

Recognising Signs and Symptoms of Heatstroke

Recognising the signs of heatstroke could be the difference between a minor health issue and a life-threatening emergency.

Common Symptoms

The most common symptoms to watch for include:

Excessive Panting and Rapid Breathing: This is one of the first indicators that your dog could be suffering from heatstroke.
May appear Agitated: One warning sign of heatstroke in dogs is agitation, as they may seem restless or unable to settle.
Drooling and Foam around the Mouth: Increased salivation is the body’s response to overheating and may appear foamy as heatstroke progresses.
Lethargy or Weakness: Dogs may slow down and become sluggish. They may also have difficulty standing.
Bright Red or Pale Gums: Bright red or pale gums can be a warning sign of heatstroke in dogs, indicating potential overheating or distress.

If you notice any of these symptoms contact your vet immediately!

Severe Symptoms of Heatstroke in Dogs

The below symptoms are common when a dog has severe heatstroke. Immediate veterinary intervention is critical as the risk of fatal complications increases significantly.

Seizure’s
Collapse
Lack of consciousness
Vomiting or Diarrhoea

Immediate Treatment for Heatstroke

If you suspect heatstroke, it’s crucial to swiftly lower their body temperature without adding additional stress.

Step-by-Step Treatment

Move to a Cool Area: Immediately bring the dog to a shaded or air-conditioned environment. Getting out of direct heat is essential!

Apply Cool (Not Cold) Water: Use towels soaked in cool water and place them on areas such as the belly, neck, and paws. Avoid ice-cold water

Offer Water Gradually: Provide small sips of water, but do not force your dog to drink. Let them drink slowly. Too much water in a short period can cause other health issues.

Use a Fan or Air Conditioner: Continue to monitor their breathing and behavior closely.

Seek Veterinary help: Even if the dog improves, it’s important to visit a vet for a full assessment. Heatstroke can cause delayed complications, and a vet can check for signs of organ damage and other complications.

Preventing Heatstroke in Dogs

Prevention is the best way to protect your dog from heatstroke. Below are a few measures that owners can take to reduce the chance of Heatstroke:

Plan around Heat: Organise walks and other outdoor activities during cooler parts of the day. Early morning and late evening are when temperatures are much more manageable. This is particularly relevant during the hotter months

Shade and Water: Ensure that your dog has access to shaded areas and a constant supply of fresh water.

Limit Exercise on Hot Days: Dogs don’t often understand when to stop playing. Monitor and reduce intense exercise when temperatures rise, as even short bursts can cause overheating.

Never Leave Dogs in Cars: Cars can reach dangerous heat levels in minutes, even with the windows down. Never leave them unattended in a vehicle!

Dogs at a Higher Risk of Heatstroke

Breeds at higher risk: Breeds such as Bulldogs, Pugs, and other flat-faced (brachycephalic) dogs, are more prone to heatstroke due to their ineffective respiratory system.
Pre-existing health conditions: Health conditions that impact the cardiovascular and or respiratory system put our patients at an increased risk.

Overweight dogs: Excess weight makes it harder for dogs to cool down efficiently, putting extra strain on their heart and lungs.
Older dogs: Aging can reduce a dog’s ability to regulate temperature, and many senior dogs have underlying health issues that increase the risk.
Working or active dogs: High-energy breeds or dogs that participate in intense activities may overexert themselves, leading to faster overheating.
Large dogs: Breeds with larger body sizes retain heat more easily, making them prone to overheating in warm environments.
Long hair or thick coats: Dogs with dense or double coats can struggle to release heat effectively, especially in hot weather.

Recognising these risk factors can help you take extra precautions to keep your dog safe during warmer months.
