Heatstroke and Heat Exhaustion in Pets (Signs & Prevention)
Heatstroke and Heat Exhaustion in Pets (Signs & Prevention)
Warm summer days mean more opportunities to get outside with your pet, whether that means an afternoon walk, time in the backyard, a road trip, or an adventure on the trails around Canmore. But pets don’t handle rising temperatures the same way we do, and sometimes they can become overheated faster than expected.
Heat exhaustion can be an early indication that your pet is struggling to regulate their body temperature. If their temperature continues to rise and their body can no longer cool itself effectively, the situation can progress to heatstroke, a potentially life-threatening medical emergency.
Knowing what overheating looks like before it reaches that point can help you make safer decisions throughout the warmer months.
Heat Exhaustion and Heatstroke Aren’t Quite the Same
Heat-related illness can develop progressively. A pet experiencing heat exhaustion is becoming too hot and having difficulty cooling down. You may notice increased panting, a desire to stop exercising, or your pet actively searching for water, shade, or somewhere cool to lie down.
Heatstroke is much more serious. It occurs when the body’s temperature rises to dangerous levels and its normal cooling mechanisms can no longer keep up. Without prompt treatment, severe overheating can affect multiple organs and become life-threatening.
There isn’t always a clear dividing line that pet owners can identify at home. That’s why responding to early signs of overheating is important rather than waiting to see how far symptoms progress.
Pets Have Their Own Way of Handling the Heat
Humans can sweat across much of the body to release heat. Pets have fewer ways to cool themselves.
Dogs primarily rely on panting, which helps release heat as moisture evaporates from the respiratory tract. They also have sweat glands in areas such as their paw pads, but these play a much smaller role in cooling the body.
Cats also use several strategies to stay comfortable, including seeking cooler areas, reducing activity, and grooming. Panting in cats is less common than in dogs and can be a sign that something isn’t right, particularly when it occurs in hot conditions.
These natural cooling mechanisms have limits. When a pet generates or absorbs heat faster than they can release it, their body temperature can continue to climb.
The Early Signs Can Be Easy to Miss
Overheating doesn’t always begin dramatically. Sometimes the first clue is simply that your pet isn’t keeping up like they normally would.
Watch for changes such as:
- Heavier or more persistent panting
- Excessive drooling
- Seeking shade or repeatedly lying down
- Slowing down or refusing to continue walking
- Restlessness
- Increased thirst
- Bright red gums or tongue
- Appearing unusually tired
Context matters too. A dog suddenly lagging behind during a warm-weather hike may be telling you something very different from a dog slowing down during a relaxed evening walk.
Don’t push your pet to continue exercising when they’re clearly struggling with the heat. Giving them an opportunity to stop and cool down early can help prevent overheating from progressing.
Know When Overheating Has Become an Emergency
As heat-related illness becomes more severe, the symptoms can change quickly.
Weakness, difficulty standing, confusion, vomiting, diarrhea, collapse, seizures, or loss of consciousness require immediate veterinary attention.
Severe heatstroke can interfere with normal circulation and damage organs throughout the body. Even if a pet appears to improve after being cooled down, veterinary evaluation may still be necessary because some complications aren’t immediately visible.
If you suspect heatstroke, contact your veterinarian or take your pet to an emergency veterinary clinic right away.
Some Pets Feel the Heat More Than Others
Any pet can overheat, but the same summer conditions aren’t equally comfortable or safe for every animal.
Flat-faced breeds such as Bulldogs, Pugs, French Bulldogs, Persians, and other brachycephalic pets deserve particular attention. Their shortened airways can make panting less efficient, which can limit their ability to release heat.
Older pets, very young animals, overweight pets, and those with heart or respiratory conditions may also have greater difficulty regulating their body temperature.
Coat type, fitness level, acclimatization to warm weather, and the intensity of an activity can also influence how well an individual pet tolerates the heat.
Rather than judging what’s safe based solely on the temperature, consider your individual pet and what you’re asking them to do in those conditions.
Heatstroke Doesn’t Only Happen Inside Hot Cars
Hot cars are a well-known heatstroke risk, but pets can also overheat during everyday outdoor activities.
Long hikes, energetic play, warm afternoon walks, limited shade or water, and strenuous exercise can all make it harder for your pet to stay cool.
Even in Canmore and the Bow Valley, pets can overheat during physical activity. Dogs may also be eager to keep hiking or playing despite becoming tired, so regular water and rest breaks are important.
Plan for the Heat Before You Head Outside
Preventing heat-related illness doesn’t mean your pet has to spend the entire summer indoors. A few adjustments can make outdoor time much safer.
Choose Cooler Times of Day
Schedule longer walks, hikes, and active play for the cooler parts of the morning or evening whenever possible. On especially warm days, shorten the activity rather than expecting your pet to maintain their usual routine.
Bring More Water Than You Think You’ll Need
Carry enough fresh water for your pet as well as yourself during longer outings. Offer regular opportunities to drink rather than waiting until your pet appears extremely thirsty.
Build Rest Into the Adventure
Find shaded areas for breaks and allow your pet to slow down when they need to. Don’t assume that because they’re still willing to chase a ball or continue down the trail, they’re comfortable doing so.
Think About the Ground Beneath Their Paws
Asphalt and other surfaces exposed to direct sunlight can become considerably hotter than the surrounding air. Whenever possible, choose shaded paths, grass, or cooler surfaces and check conditions before longer walks.
Never Rely on a Cracked Car Window
A partially open window isn’t enough to keep a parked vehicle at a safe temperature. Pets should never be left unattended in a vehicle when conditions could cause the interior to heat up.
Enjoy Summer Without Underestimating the Heat
Summer is a great time to explore Canmore and the Bow Valley with your pet, but warmer weather may require changing when, where, and how long you’re active together.
Learning your pet’s individual tolerance, planning outdoor activities around the conditions, providing plenty of water and rest, and recognizing early signs of overheating can go a long way toward preventing heat exhaustion from progressing to heatstroke.
If your pet is showing signs of heatstroke, prompt veterinary care is important. Mountain Animal Hospital provides 24-hour emergency veterinary care for pets in Canmore and the surrounding Bow Valley communities.
If you suspect your pet is experiencing heatstroke, contact Mountain Animal Hospital immediately for veterinary guidance and emergency care.
