TORONTO, ON. – July 25, 2023 – This month millions of people experienced record-breaking heatwaves across the planet. These heatwaves can be deadly, not only for humans but for their pets. Overheating can lead to heatstroke, and a dangerous elevation of body temperature that can result in shock, organ damage, abnormal blood clotting and brain damage.
Toronto Humane Society is dedicated to promoting the welfare of animals and is here to provide you with practical information on how to keep your pets safe from heatstroke. By following these guidelines, you can help keep your furry family members safe and healthy.
“Animals are at risk of overheating if they exercise vigorously on hot days, have limited access to shade, are in a poorly ventilated space or have inadequate access to water. The single most dangerous scenario is being left unattended in a hot vehicle. Temperatures in closed cars can become dangerously high in just a few minutes, often with tragic consequences. We hope that this guide can help pet parents keep their furry family members safe during heatwaves,” explains Linda Jacobson, BVSc, MMedVet(Med), PhD, Senior Manager, Shelter Medicine Advancement at Toronto Humane Society.
Without a doubt, brachycephalic dog breeds with short noses and flat faces, such as English and French bulldogs and pugs, are most at risk for heatstroke. Flat-faced cat breeds, like Persians, also have less ability to deal with heat but are less likely to be jogging with their guardian out on the trails! Dogs lose heat primarily by panting. Brachycephalic breeds struggle to lose heat this way because their airways are permanently compromised.
Aside from brachycephalics, breeds like golden retrievers, Labrador retrievers and chow chows are at higher risk than others. Young male dogs are more likely to develop heatstroke from exertion, while older dogs with respiratory problems are more likely to overheat because of high environmental temperatures. Other risk factors for heatstroke include being overweight or obese, having long hair coats, and/or having medical conditions that affect the heart and lungs, or dehydration.
“Exercise-induced collapse” is a rare genetic condition of Labradors, and some other breeds, that causes overheating and muscle weakness, or collapse, at environmental temperatures that would not be expected to cause problems in a normal dog. If you suspect your dog might have this condition, here is some information to share with your veterinarian.
Early recognition is key: Excessive panting, drooling, exhaustion, weakness, or unwillingness to walk are warning signs. Seizures, collapse, or unconsciousness due to overheating is a life-threatening emergency. The key to immediate management of heatstroke is getting the animal into a cooler place and providing active cooling. Once body temperature starts to climb, it can keep rising even without more heat exposure, so active cooling is essential.
Get a sense of the severity of the situation and react accordingly: Brachycephalic breeds with signs of heatstroke should always see a vet as soon as possible. Non-brachycephalic pets that are distressed, weak, collapsed, or unconscious, should also be seen right away. On the other hand, a healthy, fit, lean dog who is panting a lot, but is otherwise bright and happy, probably won’t need more than a rest, a good long drink, and maybe some time under the sprinkler.
If your pet shows severe signs, such as difficulty breathing or collapse, wet their coat thoroughly and get them to a veterinary clinic right away. Do not wait to see what might happen. This is one of those true emergency situations where excessive caution really pays off. Heatstroke can progress very quickly, and is extremely dangerous, but it is often treatable and reversible if care is provided soon enough. If possible, let your vet know you are on your way. The vet will measure and monitor the dog’s vital signs, monitor recovery, provide support such as oxygen and intravenous fluids, and treat more intensively if needed. They will also know when to stop cooling them, because temperatures can drop too far and too fast if cooling is too aggressive or too prolonged.
The absolute best treatment is prevention.
Speaking of sharing frozen treats, Toronto Humane Society has launched their Sweets of Summer campaign, which provides refreshing, frozen treats to animals in their shelter who are waiting to be adopted. You can support the campaign by purchasing frozen treats for the pets here. Your support not only helps a good cause but will be sure to get the animals licking their lips and wagging their tails.
