Rising summer temperatures pose a serious health threat to dogs as well as humans. Brachycephalic (short-nosed) breeds, puppies and senior dogs, thick-coated breeds, and obese dogs are particularly susceptible to heatstroke. In this article, we examine in detail the symptoms of heatstroke, risk factors, emergency response methods, and preventive measures.

1. What Is Heatstroke?
Heatstroke is a life-threatening condition that occurs when a dog’s body temperature rises above normal and the body can no longer regulate it. A dog’s normal body temperature is between 38–39.2°C (100.4–102.5°F). At 41°C (105.8°F), organ damage may occur, and at 42°C (107.6°F) or higher, fatal complications are likely.

2. Dogs at Risk

• Short-nosed (brachycephalic) breeds (French Bulldog, Pug, Boxer)

• Puppies and senior dogs

• Obese dogs

• Dogs with heart or respiratory conditions

• Thick-coated breeds

• Dogs living in hot and humid climates

---

3. Symptoms of Heatstroke

• Rapid and excessive panting

• Heavy drooling

• Trembling, dizziness, or disorientation

• Vomiting or diarrhea

• Red and dry gums

• Increased heart rate

• Weakness, collapse, or immobility

• Seizures

4. Emergency First Aid Steps
If signs of heatstroke appear, act immediately:
a) Move the dog to a shaded or cool area.
b) Pour cool (not cold) water over the body or apply wet towels.
c) Use a fan to improve air circulation.
d) Avoid ice-cold water—it may cause shock.
e) Apply cool compresses to paw pads and under the tongue.
f) Offer water to drink, but do not force it.
g) Get to a veterinarian immediately.

5. Veterinary Treatment
At the clinic, the veterinarian may provide:

• IV fluids and electrolyte support

• Oxygen therapy

• Blood tests and monitoring for organ damage

• Controlled cooling of body temperature

6. Preventive Measures

• Avoid outdoor activities during peak heat (11:00 a.m.–5:00 p.m.).

• Schedule exercise for early mornings or evenings.

• Ensure shade, cool surfaces, and access to plenty of water.

• Never leave your dog in a car—even with windows open. Temperatures can rise dangerously fast.

• Avoid shaving coats too short; natural fur provides protection.

• Use cooling mats, frozen toys, or household fans to help lower body temperature.

7. Subtle but Critical Warning Signs

• Slowed breathing combined with weakness (not just panting)

• Blue-tinged tongue (oxygen deficiency)

• Reduced pupil response or constricted pupils

8. Frequently Asked Questions

Q: My dog wants to stay in the yard. Is it safe?
A: Not during high temperatures. Even in the shade, it can be risky.

Q: Is a cold shower safe?
A: Extremely cold water can cause shock. Use lukewarm or cool water instead.

Q: Can I give my dog ice cubes?
A: Yes, if licked slowly. But consuming them too quickly may cause tooth sensitivity.

Conclusion
Heatstroke is a rapidly developing and potentially fatal condition in dogs. Recognizing the symptoms, knowing emergency response steps, and taking proper precautions during hot weather are critically important. Staying informed and attentive is the strongest way to ensure your dog enjoys a safe and healthy summer.
