Toronto summers are beautiful — patios buzzing, parks filled with picnics, and sunny waterfront walks. But for our canine companions, these warm days come with serious hidden dangers. Heatstroke is a life-threatening condition that can develop quickly, even on days that don’t feel unbearably hot to us. As responsible pet parents, understanding this risk is crucial to keeping your dog safe and happy.
🌞 What Exactly Is Heatstroke in Dogs?
Heatstroke, or hyperthermia, happens when a dog’s body temperature rises above normal and they cannot cool down effectively. Unlike humans, dogs do not sweat all over their bodies; they rely on panting and sweating through their paw pads to regulate temperature. This makes them far more vulnerable to overheating.
A dog’s normal body temperature ranges from 38 to 39°C (100.5 to 102.5°F). When their temperature rises above 40°C (104°F), internal systems begin to fail, and organs can quickly sustain irreversible damage. If not addressed immediately, heatstroke can be fatal.
⚠️ Recognizing Early Signs of Heatstroke
Catching heatstroke early is the key to saving your dog’s life. Signs often start subtly but can escalate quickly. Watch for:
- Excessive, rapid, or labored panting
- Bright red or dark gums and tongue
- Thick, sticky saliva and heavy drooling
- Weakness or collapse
- Vomiting or diarrhea, sometimes with blood
- Disorientation, staggering, or seizures
Immediate action is critical at the first sign of trouble.
🐶 Who Is Most at Risk?
All dogs can suffer from heatstroke, but certain groups are more vulnerable:
- Brachycephalic breeds (short-nosed dogs like Bulldogs, Pugs, and Boxers) who already struggle with breathing.
- Seniors and puppies, who can’t regulate temperature as well.
- Overweight dogs, since extra fat acts as insulation and traps heat.
- Dogs with heart or respiratory conditions, which limit their ability to recover.
Knowing your dog’s risk factors helps guide safer summer decisions.
🌎 Why Toronto Dogs Are Especially at Risk
Toronto may not seem like a dangerously hot city, but its unique urban environment magnifies heat risks. Pavements and asphalt absorb heat and radiate it back, creating an urban heat island effect. Even on mild days, the ground can reach temperatures high enough to burn paw pads and raise your dog’s body temperature rapidly.
Humidity makes things worse by reducing the effectiveness of panting. On humid days, even moderate exertion can tip your dog into dangerous territory. In Toronto, it’s not uncommon for sidewalks to reach 50°C (122°F) when the air is only 24°C (75°F).
🕒 Common Risky Scenarios
Many well-meaning dog parents unintentionally put their dogs in harm’s way. Some common scenarios include:
- Walking during peak midday heat (11 a.m.–4 p.m.).
- Taking long walks without water breaks.
- Letting dogs play too energetically at dog parks.
- Leaving dogs on balconies or in sun-exposed yards with no shade.
- Leaving dogs in parked cars — even for a few minutes, this can be deadly.
Being aware of these situations is the first step to prevention.
❄️ What to Do If You Suspect Heatstroke
If you see signs of heatstroke, act immediately:
- Move to a shaded, cool area right away.
- Offer small sips of cool (not ice-cold) water. Never force your dog to drink.
- Wet their paws, ears, and belly with cool water using a damp cloth or spray bottle. Avoid full immersion in ice baths, as this can cause blood vessel constriction and worsen the condition.
- Call your veterinarian or an emergency clinic right away. Heatstroke is always a medical emergency.
Some 24/7 Toronto emergency clinics include:
- VEC Toronto (Yonge & Davenport)
- Toronto Animal Health Partners (North York)

- Always opting for solo walks so your dog’s needs set the pace.
Every dog is different, and we personalize every outing accordingly.
🪿 Practical Tips for Pet Parents
When temperatures rise, here’s how you can protect your pup:
- Avoid walking on hot pavement; use the “7-second rule” — if you can’t hold your hand comfortably on the pavement for seven seconds, it’s too hot.
- Schedule walks early in the morning or after sunset.
- Provide plenty of fresh, cool water at home and during outings.
- Keep your dog inside during peak heat hours, preferably with fans or AC.
- Add ice cubes to water bowls or provide cooling mats.
- Never leave your dog unattended in a car, even with the windows cracked.
- Monitor your dog’s behavior after exercise for signs of overheating.
💡 Additional Considerations
Some dogs might enjoy water play to stay cool, such as shallow kiddie pools or playing with a gentle hose spray. However, always supervise closely and ensure they don’t overexert themselves.
Consider investing in cooling vests or bandanas, which can help regulate body temperature during short outdoor activities. Always consult your vet about appropriate options for your dog’s breed and health condition.
Be mindful of grooming — while it may seem logical to shave a thick-coated dog in summer, their coat actually helps regulate body temperature and protect from sunburn. Discuss trimming or grooming needs with a professional groomer familiar with your dog’s breed.
