Summer brings longer days and more opportunities to enjoy the outdoors with your dog. But as the temperature rises, so does the risk of heat-related emergencies—especially heatstroke. Dog heatstroke is a serious condition that can develop quickly and lead to life-threatening complications if not recognized and addressed promptly. Knowing what to look for and how to prevent it can make all the difference. This blog breaks down the signs of dog heatstroke, what causes it, and the steps you can take to protect your pet—so you both can enjoy warm-weather adventures safely.
What Is Dog Heatstroke?
Dog heatstroke occurs when your dog’s body temperature rises to dangerous levels and their body cannot cool down on its own. Unlike humans, dogs don’t sweat through their skin—they rely on panting to regulate their temperature. When the heat becomes too intense or your dog is unable to cool off, their internal systems can start to shut down.
How Dog Heatstroke Happens
Dog heatstroke typically results from exposure to high temperatures, especially when paired with humidity and poor ventilation. Dogs left in cars, exercised in hot weather, or confined without shade and water are at the highest risk. Some dogs may also overheat simply by lying in direct sunlight for too long.
Dogs at Greater Risk
While any dog can develop heatstroke, certain breeds and conditions increase susceptibility:
- Brachycephalic (flat-faced) breeds like Bulldogs and Pugs
- Puppies and senior dogs
- Dogs with thick or dark-colored coats
- Overweight dogs
- Pets with underlying health issues
Early Signs of Dog Heatstroke
Catching heatstroke early gives your dog the best chance at recovery. Mild symptoms can progress quickly, so it’s important to monitor your dog closely during warm weather.
Symptoms to Watch For
- Excessive panting or drooling
- Red or pale gums
- Lethargy or weakness
- Confusion or disorientation
- Vomiting or diarrhea
- Rapid heart rate
- Glassy eyes
If your dog shows one or more of these symptoms during or after being in the heat, they could be experiencing dog heatstroke.
Advanced Signs of a Heatstroke Emergency
Once heatstroke progresses, it can become a medical emergency that requires immediate veterinary attention.
Severe Symptoms of Dog Heatstroke
- Collapsing or inability to stand
- Seizures
- Bloody diarrhea or vomit
- Muscle tremors
- Loss of consciousness
At this stage, your dog’s organs may be under extreme stress. If you suspect your dog is experiencing heatstroke, call Harlingen Veterinary Clinic at (908) 359-2000 right away or bring them in for emergency care.
Common Causes of Dog Heatstroke
Understanding how dog heatstroke happens can help you take steps to prevent it.
High-Risk Situations
- Being left in a car—even with windows cracked
- Heavy exercise during the hottest parts of the day
- Long walks on hot pavement
- Being confined without airflow, shade, or water
- Lack of supervision in hot backyards or parks
Even short exposure to extreme heat can be dangerous, especially in humid climates like New Jersey’s summer season.
How to Prevent Dog Heatstroke
Preventing dog heatstroke starts with awareness and preparation. Knowing the conditions that increase risk—and avoiding them—can help protect your pet.
Smart Summer Habits
- Walk your dog early in the morning or after sunset when temperatures are lower
- Keep outdoor playtime short on hot days
- Always provide access to fresh, cool water and shade
- Avoid long car rides without climate control
- Never leave your dog unattended in a vehicle
Cooling Tools and Techniques
- Use cooling mats or vests for brachycephalic or senior dogs
- Provide kiddie pools or splash areas in the yard
- Keep indoor spaces well-ventilated with fans or air conditioning
Safe Alternatives for Exercise
Instead of long runs or high-energy play outdoors, consider indoor enrichment like puzzle feeders, scent games, or basic training exercises to help your dog stay mentally and physically active.
What to Do If You Suspect Heatstroke
If your dog shows symptoms of dog heatstroke, time is critical. Contact your veterinarian at Harlingen Veterinary Clinic right away. Avoid attempting to treat the condition on your own, as improper cooling can cause shock or further complications.
