Every summer, veterinarians see more cases of pets struggling with heat. A recent report in Veterinary Practice News Canada highlights this growing concern, with new data from Trupanion showing a steady rise in claims for dehydration and heatstroke among Canadian pets between 2020 and 2024.
This trend is worrying for both pet parents and veterinarians. It reminds us that while playing pets bring us joy and companionship, but at the same time they are also exposed to extreme heat. Being proactive is the best way to keep them safe.
Why Heat Illness in Pets Is on the Rise
Over the past five years, nearly 2,500 Canadian pets have been treated for heat-related illnesses. Most were dehydration cases, which rose by almost 20% in just one year. Heatstroke is less common but far more dangerous, with incidents surging by 125% during summer months. Since these figures only cover insurance claims, the real number of pets affected is likely much higher, showing just how seriously hot weather impacts pet health.
Several factors are driving this increase. Hotter summers and more frequent heatwaves are making it harder for pets to stay safe, especially when they spend long hours outdoors for walks, play or travel. Some breeds, like bulldogs, pugs and Persians, are even more vulnerable because they struggle to cool themselves effectively. Its pet parents that need to stay extra cautious during warm weather.
How to Prevent Heat Illness in Pets
Most pet parents already understand the basics, fresh water, cooler walks and avoiding hot cars. But preventing heat illness goes beyond these simple steps:
1. Test Pavement Temperature Before Walks
Hot pavement can burn paw pads and increase body heat. Place your hand on the ground for five seconds, if it’s too hot for your hand, it’s too hot for your pet. Choose grassy areas or shaded paths for walks instead.
2. Use Cooling Aids Effectively
Cooling mats, damp towels or specially designed cooling vests can help pets regulate their body temperature. For dogs that resist lying on mats, try dampening a bandana and tying it loosely around their neck.
3. Offer Hydration in Multiple Ways
Some pets are picky about drinking water. Encourage hydration by offering ice cubes to lick, adding water to kibble or using pet water fountains that keep water moving and fresh. These tricks can make a real difference on hot days.
4. Adjust Grooming and Coat Care
Regular brushing your pet’s coat helps remove excess fur that can trap heat and restrict airflow. However, avoid shaving double-coated breeds like huskies or retrievers, as their coat provides natural insulation against both heat and sunburn. Instead, keep them well-groomed to promote airflow.
5. Recognize Early Warning Signs of Heat Stress
Early signs include heavy panting, drooling, slowing down or seeking shade. Acting quickly can prevent escalation and if you’re unsure, confirm with your vet through a call, chat or teleconsultation for timely guidance.

6. Create a Cooling Routine at Home
Keep one room in the house extra cool with fans or air conditioning as a “safe zone” where pets can retreat. If outdoors, set up shaded areas with access to water play, sprinklers or shallow kiddie pools work well for dogs that enjoy water.
7. Plan Travel and Outdoor Activities Carefully
On trips, use reminders to schedule shaded breaks every 1–2 hours and carry cooling gear like water sprays or mats. Keep outdoor play sessions brief with regular rest stops to prevent overheating.

8. Know When Veterinary Care Is Urgent
Seek immediate veterinary help if your pet refuses water, keeps panting heavily after rest, collapses or shows signs like confusion or seizures. Heatstroke can escalate quickly and urgent medical care is often the only way to save your pet.

No pet is completely safe from the dangers of extreme heat, but most cases of heat illness can be prevented with awareness and timely action. By making small adjustments to daily routines, watching for early warning signs and seeking veterinary help when needed, pet parents can protect their companions from serious harm. With the right care and a little extra vigilance, our pets can enjoy the summer months safely and comfortably.
