Heat Stroke in Dogs: How to Keep Your Pup Cool, Safe, and Happy This Summer

Summer is a time for sunshine, long walks, and outdoor adventures with your dog — but it also brings serious risks when it comes to heat stroke. Every year, countless dogs suffer needlessly from heat-related illnesses, and tragically, many cases could have been prevented with a little awareness and preparation.

At Grace K9, your dog’s health and happiness is always our priority. Let’s break down what you need to know about heat stroke in dogs: how to spot it, how to prevent it, and what to do (and not do) if it happens.

What Is Heat Stroke in Dogs?

Heat stroke (also known as heat exhaustion or heat stress) occurs when your dog’s body temperature rises dangerously high and they are no longer able to cool themselves down. Unlike humans, dogs don’t sweat all over their bodies — they rely on panting and limited sweat through their paw pads to regulate their temperature. This makes them far more vulnerable to overheating.

Dangerous temperature ranges for dogs:

• Normal dog body temperature: 101°F to 102.5°F (38.3°C to 39.2°C)

• Heat stroke begins around: 104°F (40°C)

• Critical/life-threatening: 106°F+ (41.1°C+)
  

Breeds More Susceptible to Heat Stroke

While all dogs can suffer heat stroke, some are especially vulnerable:

• Brachycephalic breeds (flat-faced) like Bulldogs, Pugs, Boxers, Boston Terriers, and French Bulldogs

• Thick-coated breeds like Huskies, Bernese Mountain Dogs, and Newfoundlands

• Senior dogs and puppies (they struggle more to regulate temperature)

• Dogs with health conditions (respiratory, heart issues, obesity)

Early Warning Signs of Overheating (Time to Intervene Immediately):

• Heavy, excessive panting

• Seeking shade or lying down suddenly during activity

• Bright red gums or tongue

• Glassy eyes

• Restlessness or agitation

• Weakness, wobbliness, or slowing down dramatically

Signs of Heat Stroke (Emergency — Seek Veterinary Care Immediately):

• Rapid heart rate

• Excessive drooling

• Vomiting or diarrhea (sometimes with blood)

• Lethargy or confusion

• Collapse

• Seizures

• Body temperature over 104°F (if you can check safely)

What To Do If You Suspect Heat Stroke in Your Dog:

1. Move your dog immediately to a cool, shaded area or indoors with air conditioning.

2. Offer small sips of cool (not cold) water. Do not force water if your dog is refusing or struggling to drink.

3. Use lukewarm water to cool your dog gradually. Focus on the armpits, paws, belly, and inner thighs. Cool wet towels can help.

4. Use a fan to help evaporation.

5. Go straight to your veterinarian. Heat stroke can cause delayed organ damage — even if your dog seems to “recover,” medical care is essential.

What NOT To Do:

🚫 Do not dunk your dog in ice-cold water. This can cause shock and worsen the situation.🚫 Do not cover your dog in wet towels for extended periods. This can trap heat rather than help it escape.

🚫 Avoid food or large amounts of water immediately post-overheating. Panting dogs swallow air, and sudden food or water intake can increase the risk of bloat (GDV), especially in large or deep-chested breeds. Allow breathing to settle first.

Mindful Summer Safety Tips:

1. Know the Temperature: and Not Just the Air! Ground surface matters. Asphalt, concrete, and sand can burn paw pads quickly. A good rule of thumb: If you can’t hold your hand comfortably on the surface for 7 seconds, it’s too hot for your dog’s paws.

2. Avoid Peak Heat Hours: Walk early in the morning or later in the evening when temperatures are lower.

3. Provide Shade and Cool Rest Areas: Whether you’re at home or out and about, ensure your dog always has access to a shady, ventilated spot to rest.

4. Hydrate Smartly: Keep fresh, cool water available at all times — but avoid encouraging frantic drinking during periods of heavy panting.

5. Adjust Activity Levels: Skip the fetch, long runs, and strenuous hikes during heat waves. Gentle sniffari walks in cooler times of day are a safer choice.

Final Thought: Prevention Is Key

Heat stroke can come on fast and escalate quickly. Staying aware of your dog’s limits, watching the weather, and learning the early signs could be the difference between a fun summer and a devastating emergency.
