Signs of Heatstroke in Dogs Every Owner Should Know

As temperatures rise during spring and summer, it's important for dog owners to understand the risks associated with heat and hot weather.

Dogs cannot regulate their body temperature as effectively as humans, which means they can quickly become overheated in warm conditions. Heatstroke is a serious condition that requires immediate attention and can become life-threatening if left untreated.

In this guide, we'll explain the common signs of heatstroke in dogs, what to do if you suspect your dog is overheating, and how to help prevent heat-related problems.

Quick Guide

✓ Excessive panting

✓ Drooling more than usual

✓ Lethargy or weakness

✓ Bright red gums or tongue

✓ Vomiting or diarrhoea

✓ Difficulty walking or collapse

✓ Seek veterinary assistance immediately if you suspect heatstroke

What Is Heatstroke?

Heatstroke occurs when a dog's body temperature rises beyond its ability to cool itself effectively.

Unlike humans, dogs primarily regulate their temperature through panting and limited sweating through their paw pads. During hot weather, strenuous exercise or poor ventilation, they may struggle to cool down sufficiently.

Heatstroke can develop quickly and should always be treated as a veterinary emergency.

Common Signs of Heatstroke in Dogs

Knowing the warning signs can help you act quickly.

Look out for:

•  Excessive panting
•  Heavy drooling
•  Rapid breathing
•  Bright red or dark red gums
•  Increased heart rate
•  Weakness or lethargy
•  Restlessness
•  Vomiting
•  Diarrhoea
•  Difficulty standing or walking
•  Collapse

If you notice any of these symptoms, move your dog to a cool area and contact your vet immediately.

Dogs More at Risk

Some dogs may be more vulnerable to heat-related problems, including:

•  Flat-faced breeds (such as Bulldogs, Pugs and French Bulldogs)
•  Older dogs
•  Puppies
•  Overweight dogs
•  Dogs with existing health conditions
•  Dogs exercising during warm weather

Extra care should be taken with higher-risk pets, particularly during hot summer days.

What To Do If You Suspect Heatstroke

Step 1: Move Your Dog to a Cooler Area

Take your dog into the shade or a cool, well-ventilated area as soon as possible.

Step 2: Offer Cool Water

Provide fresh drinking water but do not force your dog to drink.

Step 3: Begin Gentle Cooling

Use cool (not ice-cold) water to help gradually lower your dog's temperature.

Avoid sudden or extreme cooling methods.

Step 4: Contact Your Vet Immediately

Even if your dog appears to improve, veterinary assessment is strongly recommended.

Heatstroke can cause internal complications that may not be immediately visible.

How to Help Prevent Heatstroke

Prevention is always better than treatment.

Simple ways to help keep your dog safe include:

•  Walk your dog during cooler parts of the day
•  Carry fresh water on walks
•  Avoid strenuous exercise during hot weather
•  Provide access to shade
•  Ensure good ventilation
•  Monitor your dog closely on warm days

Never Leave a Dog in a Vehicle

Never leave your dog unattended in a car, even for a short period.

Vehicle temperatures can rise rapidly and become dangerous within minutes, even when the weather does not feel excessively hot.
