Dog Heatstroke: Signs, Symptoms, Treatment and Prevention

Dog heatstroke occurs when a dog’s body temperature rises to a dangerous level and the body cannot cool down efficiently. Because dogs release heat differently than humans, they can overheat faster, especially in high temperatures or during intense activity. Dog heatstroke can become life-threatening quickly, so recognizing the signs and knowing when to take action matters. If you have any concerns about dog heatstroke in Las Vegas, call Sahara Pines Animal Hospital at (702) 876-7580 or book an appointment online today.

What Causes Dog Heatstroke?

Dog heatstroke happens when a dog is exposed to high temperatures or intense exertion and cannot cool their body effectively. Dogs primarily release heat through panting, but this system has limits. When the air is hot, humid, or still, panting may not provide enough cooling. As a result, body temperature rises quickly.

Common Contributing Factors

• High outdoor temperatures, especially during summer or mid-day hours
• Limited access to shade or water
• Exercising during peak heat
• Being confined in hot, enclosed spaces, such as a parked vehicle or poorly ventilated room
• Underlying health conditions, such as respiratory or cardiac issues

Higher Risk Dogs

Some dogs become overheated more quickly than others. These include:

• Short-nosed (brachycephalic) breeds, such as Bulldogs, Pugs, and Shih Tzus
• Dogs with thick coats
• Puppies and senior dogs
• Overweight dogs

Living in a desert climate like Las Vegas can increase the likelihood of dog heatstroke, so awareness is key.

Signs to Watch Out For 

Spotting dog heatstroke early can prevent the condition from becoming severe. Even mild overheating should be taken seriously, as it can progress quickly.

Early Signs

• Heavy, persistent panting
• Excessive drooling
• Bright red gums or tongue
• Elevated heart rate
• Restlessness or pacing

Progressing Symptoms

• Vomiting or diarrhea
• Weakness or inability to stand steadily
• Disorientation or confusion
• Collapse or unresponsiveness

Why Symptoms Escalate Quickly

Dog heatstroke affects the entire body. As body temperature rises, the organs begin to struggle. Heat can impact the nervous system, digestive system, and cardiovascular system, which is why severe cases require prompt veterinary support. If your dog shows signs of dog heatstroke, call Sahara Pines Animal Hospital at (702) 876-7580 right away.

How Veterinarians Diagnose and Support Dogs with Heatstroke

If dog heatstroke is suspected, your veterinarian will assess your dog’s temperature, hydration levels, and organ function. Because each case is different, your dog’s veterinary care will be tailored to their condition and needs. Our team at Sahara Pines Animal Hospital may perform diagnostic tests to evaluate internal systems and make informed care decisions.

What to Expect During the Visit

• Temperature measurement
• Evaluation of gum color and hydration
• Bloodwork to check internal organ function
• Monitoring heart and respiratory rates

Treatment focuses on stabilizing your dog and supporting their recovery in a controlled environment. Once your dog is stable, your veterinarian may recommend ways to manage activity levels and heat exposure going forward.

Tips for Preventing Dog Heatstroke in Las Vegas

Preventing dog heatstroke starts with understanding your dog’s limits and planning outdoor activities with the weather in mind. Because Las Vegas temperatures can climb quickly, even short periods outside can impact your dog.

Daily Prevention Tips

• Walk during cooler hours, such as early morning or later in the evening.
• Provide shade and water anytime your dog is outdoors.
• Bring water on walks and offer frequent drink breaks.
• Avoid hot surfaces, which can heat your dog from the paws upward.

Activity Awareness

Even dogs who love running and playing need breaks. Rotate between activity and rest, especially outdoors. Monitor panting, energy levels, and behavior closely.

Home and Travel Safety

• Never leave your dog in a parked car.
• Ensure your home has working air conditioning or cooling options.
• Create cool zones indoors, such as shaded bedding or tile floors.

Keeping prevention in mind every day helps reduce the risk of dog heatstroke significantly.
