Suspected heatstroke is always an emergency. Begin cooling immediately and seek veterinary care right away, even if symptoms seem to ease.
Call us at (905) 576-8885. If we are closed, go directly to the nearest emergency veterinary hospital.
Heatstroke is one of the fastest-moving emergencies we see, sometimes developing within just a few minutes of exposure to heat.
Because it progresses so quickly, knowing the warning signs and exactly what to do can genuinely make the difference in your dog’s outcome.
At Wilson Road Vet Clinic, Dr. Yessa wants every Oshawa dog owner to know these warning signs before they need them.
This Is a Medical Emergency
If you suspect heatstroke, do not wait to see if your dog improves on their own. Begin cooling measures immediately and seek veterinary care right away, even if symptoms seem to be easing.
Warning Signs of Heatstroke
- Heavy, uncontrolled panting
- Bright red or purple gums and tongue
- Excessive drooling
- Weakness, stumbling, or disorientation
- Vomiting or diarrhea
- Collapse or seizures, in severe cases
Situations That Commonly Cause Heatstroke
- Being left in a parked car, even briefly
- Vigorous exercise on a hot or humid day
- Being outside without shade or water access
- Extended time in a hot yard, especially for flat-faced or heavy-coated breeds
What to Do Right Now
- Move your dog to a cool, shaded, or air-conditioned area immediately
- Offer small amounts of cool (not ice-cold) water if they’re alert enough to drink
- Apply cool, wet towels to the belly, paws, and neck
- Use a fan if available to help with evaporative cooling
- Call us or head to the nearest emergency veterinary hospital right away, while continuing to cool your dog en route
What Not to Do
- Do not use ice or ice-cold water, which can worsen the situation by restricting blood flow
- Do not force water into a dog who isn’t alert or able to swallow safely
- Do not assume your dog is fine just because panting has slowed
Why Veterinary Care Is Still Necessary
Even if your dog seems to improve with initial cooling, heatstroke can cause internal damage that isn’t immediately visible, including effects on the kidneys, clotting system, and other organs. Veterinary evaluation is important even after apparent recovery.

Frequently Asked Questions
How quickly can heatstroke become dangerous?
It can progress within minutes, which is why immediate action matters.
What should I do first if I suspect heatstroke?
Move your dog to a cool area and begin gentle cooling with cool water and towels while arranging veterinary care immediately.
Should I use ice to cool my dog down?
No, ice or ice-cold water can be counterproductive. Use cool, not cold, water instead.
Which dogs are most at risk for heatstroke?
Flat-faced breeds, senior dogs, overweight dogs, and those with thick coats are at higher risk.
Does my dog still need to see a vet if they seem better after cooling?
Yes, internal effects of heatstroke aren’t always visible right away, so veterinary evaluation is still important.
Can heatstroke happen even on a mild day?
Yes, especially in a parked car, where temperatures can rise quickly even when it doesn’t feel very hot outside.
Is heatstroke ever not an emergency?
No, suspected heatstroke should always be treated as an emergency and evaluated by a veterinarian.
What if this happens outside of your clinic hours?
Please go directly to the nearest emergency veterinary hospital while continuing cooling measures on the way.
