First Aid for Canine Heat Stroke

Heat stroke in dogs can happen quickly, and it’s a true medical emergency. When a dog’s body temperature rises above 104°F (normal is 101–102.5°F), they enter dangerous territory that can lead to organ failure or even death. Knowing the signs and how to react could make all the difference.

In this final blog of our series, we’ll guide you step-by-step on what to do if your dog is overheating, how to lower their temperature safely, and when to seek emergency veterinary care.

Recognizing the Signs of Heat Stroke

Early detection is key. Here are common signs that your dog may be experiencing heat stroke:

• Heavy or rapid panting

• Bright red or pale gums

• Thick, sticky drool

• Vomiting or diarrhea

• Glazed eyes or confusion

• Weakness, staggering, or collapse

• Seizures or unconsciousness

If you observe even a few of these symptoms, act immediately. Time is critical.

Step-by-Step First Aid Response

1. Move Your Dog to a Cooler Location

Get your dog out of the heat immediately—into an air-conditioned building, car, or a shaded area. Remove any harness or tight collar that might restrict breathing.

2. Offer Cool (Not Ice-Cold) Water

Encourage your dog to drink small amounts of cool water. Never force water into their mouth—it can lead to choking. If they refuse water or cannot swallow, skip this step and move to cooling.

Avoid: Ice water or large amounts of water at once, which can trigger shock.

3. Begin Cooling Slowly

You want to reduce your dog’s body temperature gradually, not suddenly.

• Wet towels: Soak towels in cool water and place them on your dog’s belly, paws, armpits, and groin area. Re-wet as needed.

• Use a fan: Blow air over the wet towels to enhance cooling.

• Cool (not cold) bath or hose down: If available, submerge your dog in a tub of cool—not icy—water or hose them gently.

Never immerse your dog in ice water—it can constrict blood vessels and trap heat inside.

4. Take Their Temperature if You Can

Use a digital rectal thermometer if you have one. You want to reduce your dog’s body temperature to 103°F—no lower. Once they hit 103°F, stop active cooling to prevent hypothermia.

If you don’t have a thermometer, continue gentle cooling until they seem more alert and their panting slows.

5. Call Your Veterinarian or Head to the Emergency Vet

Even if your dog appears to be recovering, always follow up with a vet. Internal damage can occur that may not be immediately visible. Organ failure, clotting disorders, and neurological symptoms are all possible complications from heat stroke.

Call ahead to let the clinic know you’re coming—they may prep emergency treatment before you arrive.

What NOT to Do

• Don’t use ice or ice water: Rapid cooling can send your dog into shock.

• Don’t delay treatment: Waiting to “see if they get better” could cost precious time.

• Don’t leave them unattended: Dogs can crash quickly and need constant supervision during and after a heat episode.

What Happens at the Vet?

Your vet will assess your dog’s temperature and overall condition. Emergency treatment may include:

• IV fluids to treat shock and dehydration

• Oxygen therapy

• Cooling techniques like fans and alcohol swabs on paw pads

• Bloodwork to check for organ function or clotting issues

• Hospitalization for monitoring

The sooner your dog gets to a professional, the better their odds of a full recovery.

Preventing Heat Stroke: A Final Word

Now that you’ve read the full series, here’s a recap of how to prevent heat stroke before it starts:

• Avoid midday walks and hot pavement

• Always offer fresh water

• Never leave your dog in a hot car

• Use cooling gear and fans

• Recognize your dog’s limits and breed-specific risks

• Watch closely for early signs of distress

Your dog counts on you to keep them safe—especially when they can’t regulate their own body temperature.

Conclusion

Heat stroke in dogs is terrifying, but knowledge is power. By acting quickly and calmly, you can stabilize your dog and give them the best chance at recovery. Pair this first aid knowledge with proactive prevention, and you’ll both be ready to enjoy summer safely and confidently.
