Catching Heatstroke Symptoms in Dogs Before They Become Dangerous

Summer in Greenville is no joke—hot, humid, and perfect for outdoor adventures. But while we might enjoy the sunshine, it can be dangerous for our four-legged friends. At Partners Animal Hospital Greenville, we want pet parents to know the signs of heatstroke before it becomes life-threatening.

Here’s how to keep your dog safe and cool when the temperature climbs.

What Is Heatstroke?

Heatstroke is a form of hyperthermia that happens when a dog’s body temperature rises above 104°F and they can’t cool down. Dogs don’t sweat like humans—they pant to release heat. But in extreme temps, especially with high humidity, panting alone may not be enough.

Without quick action, heatstroke can cause organ failure, brain damage, or even death.

Who’s Most at Risk?

All dogs are vulnerable to heatstroke, but some are at higher risk:

• Flat-faced (brachycephalic) breeds like Bulldogs, Boxers, and Pugs
• Senior dogs or those with heart or respiratory conditions
• Overweight dogs
• Puppies
• Dogs with thick coats or limited access to shade and water

Even a short walk or backyard playtime during peak heat can put them in danger.

Early Signs of Heatstroke

Catching the signs early can save your dog’s life. Watch for:

• Excessive panting or drooling
• Bright red or pale gums
• Lethargy or weakness
• Disorientation or stumbling
• Vomiting or diarrhea
• Collapse or seizures (a sign of severe heatstroke)

If you notice any of these symptoms, act fast.

What to Do in a Heatstroke Emergency

1. Move your dog to a cooler area immediately—indoors or shaded.
2. Offer small amounts of cool (not cold) water—never force them to drink.
3. Wet their body with lukewarm water—use towels or a hose if needed.
4. Call us or an emergency vet right away—heatstroke is a medical emergency.

Do NOT use ice or ice-cold water, as this can cause blood vessels to constrict and slow down cooling.

Prevention Is Key

• Walk your dog early in the morning or late in the evening
• Always bring water and take breaks on walks
• Never leave your dog in a parked car—not even for a minute
• Provide shade and airflow if your dog is outside
• Consider cooling mats or vests for extra-hot days

If it feels too hot for you, it’s definitely too hot for your dog.
