Utah summers are made for outdoor adventures. Whether you're hiking the Wasatch Mountains, walking through your neighborhood, visiting a local park, or relaxing in the backyard, it's only natural to include your pets in the fun. But while warm weather encourages more time outside, it also increases the risk of heatstroke, one of the most serious medical emergencies dogs and cats can experience.
At Canyon View Cares Veterinary Hospital in Layton, we want pet owners to enjoy everything summer has to offer while helping their pets stay healthy and safe. Heatstroke can develop faster than many people expect, but learning to recognize the early warning signs can make all the difference. Acting quickly may prevent a medical emergency and could even save your pet's life.
Understanding Heatstroke
Heatstroke occurs when a pet's body temperature rises beyond the point where it can cool itself naturally. As internal temperature climbs, the body's organs begin to experience stress and damage. Without immediate treatment, heatstroke can lead to dehydration, organ failure, seizures, shock, and death.
Unlike humans, dogs and cats have limited ways to cool themselves. Dogs depend primarily on panting, while cats cool themselves by grooming and through minimal sweating from their paw pads. During periods of high temperatures or vigorous activity, those natural cooling methods simply aren't enough.
Once a pet's body temperature begins rising rapidly, time becomes extremely important.
Heatstroke Can Happen Almost Anywhere
Many people think heatstroke only occurs after being left inside a parked vehicle. While hot cars remain one of the most dangerous situations for pets, they are far from the only cause.
Pets can become overheated while:
- Hiking on warm afternoons
- Playing fetch at the park
- Running alongside bicycles
- Spending time in fenced backyards
- Attending outdoor family events
- Walking on hot sidewalks
- Traveling without adequate air conditioning
Even temperatures that seem comfortable to people can become dangerous for pets, especially if they're exercising or belong to a higher-risk group.
Early Signs That Your Pet May Be Overheating
One advantage pet owners have is that heatstroke often develops in stages. Most pets begin showing warning signs before their condition becomes critical.
Watch for:
- Heavy panting
- Excessive drooling
- Rapid breathing
- Bright red gums
- Increased heart rate
- Weakness
- Slowing down during activity
- Reluctance to continue walking
- Vomiting
- Diarrhea
- Lethargy
Some pets may repeatedly seek shade or lie on cool surfaces. Others may become unusually quiet or stop participating in activities they normally enjoy.
Never ignore these changes during warm weather.
When Heatstroke Becomes an Emergency
If body temperature continues rising, symptoms become much more severe.
Emergency warning signs include:
- Difficulty standing
- Loss of coordination
- Collapse
- Confusion
- Tremors
- Seizures
- Pale or bluish gums
- Bloody diarrhea
- Loss of consciousness
These symptoms indicate a medical emergency that requires immediate veterinary care.
The sooner treatment begins, the better your pet's chances for a full recovery.
Which Pets Are More Vulnerable?
Although any pet can develop heatstroke, some animals are naturally more susceptible.
Flat-Faced Breeds
Brachycephalic breeds have shorter airways that make cooling through panting much less effective.
Examples include:
- French Bulldogs
- Bulldogs
- Pugs
- Boston Terriers
- Shih Tzus
Persian and Himalayan cats are also at increased risk.
Senior Pets
Older pets often have reduced cardiovascular function or chronic medical conditions that make hot weather more difficult to tolerate.
Puppies and Kittens
Young pets haven't fully developed their ability to regulate body temperature and can overheat quickly.
Overweight Pets
Excess body weight traps heat and places additional stress on the heart and lungs.
Pets with Medical Conditions
Heart disease, respiratory disorders, obesity, and endocrine diseases all increase the likelihood of heat-related illness.
Owners of these pets should take extra precautions whenever temperatures rise.
Hot Pavement Can Add to the Problem
The outside temperature doesn't tell the whole story.
Concrete sidewalks, asphalt parking lots, and playground surfaces absorb heat throughout the day and often become much hotter than the surrounding air.
Walking on these surfaces can burn paw pads while also increasing a pet's body temperature.
Before every walk, place the back of your hand on the pavement for several seconds. If it's too hot for your hand, it's too hot for your pet's paws.
Choosing grassy trails and walking during the early morning or evening can help reduce these risks.
Never Leave a Pet in a Parked Vehicle
Even with windows cracked open, temperatures inside a parked car can rise dramatically within minutes.
Every summer, preventable heatstroke cases occur because owners underestimate how quickly a vehicle heats up.
The safest rule is simple: if your pet cannot come inside with you, they should stay home in a cool environment.
What Should You Do If Your Pet Is Overheating?
If you think your pet may be suffering from heatstroke, don't wait for symptoms to worsen.
- Move them into a shaded or air-conditioned area immediately.
- Offer small amounts of cool drinking water.
- Apply cool water to the belly, paws, legs, and neck. Avoid using ice or ice water because cooling too rapidly may interfere with the body's natural response.
- Use a fan to improve air circulation if one is available.
- Contact your veterinarian immediately.
Even if your pet seems much better after cooling down, they still need a veterinary examination. Heatstroke can cause internal injuries that aren't immediately visible.
Preventing Heatstroke Starts with Good Habits
Fortunately, preventing heatstroke is usually much easier than treating it.
Simple ways to protect your pet include:
- Scheduling walks during cooler morning or evening hours.
- Carrying fresh water on every outing.
- Taking regular breaks during exercise.
- Limiting vigorous activity on hot days.
- Providing access to shade whenever pets are outdoors.
- Keeping pets indoors during the hottest afternoon hours.
- Watching closely for signs of fatigue or excessive panting.
- Adjusting activities based on your pet's age, breed, and overall health.
These small changes can significantly reduce your pet's risk of overheating.
Enjoy Every Season Safely
Summer should be a time for making memories with your pet, not rushing to the emergency hospital. By understanding how heatstroke develops and recognizing the earliest warning signs, you can help prevent a dangerous situation before it becomes life-threatening.
If your dog or cat begins panting heavily, drooling excessively, slowing down, or acting differently during warm weather, don't wait to see if the symptoms improve on their own. Early action and prompt veterinary care can make all the difference.
