What is Dog Heatstroke and Why Does it Happen? 

Dog heatstroke occurs when a dog’s body temperature exceeds 39.4°C (103°F), typically due to prolonged exposure to high heat and humidity without adequate ventilation or hydration. Unlike humans, dogs cannot sweat to cool down effectively. Instead, they rely on panting, which becomes insufficient under extreme heat. Common causes include being left in a hot car, outdoor exercise during peak sun hours, or inadequate shade. In Hong Kong's hot and humid summers, pet owners must stay vigilant to prevent this potentially fatal condition. Dogs with thick coats or pre-existing health conditions are especially at risk.

Early Signs of Overheating: 6 Symptoms Every Dog Parent Should Know

Spotting early signs can save lives. Watch for these six red flags:

  1. Heavy panting
  2. Drooling
  3. Lethargy
  4. Red or pale gums
  5. Vomiting or diarrhea
  6. Lack of coordination

These symptoms indicate your dog is struggling to regulate their body temperature. Quick action can prevent escalation to severe heatstroke. Provide water, shade, and rest immediately. Always observe your dog's behavior during outdoor time, especially in high humidity.

High-Risk Dog Breeds and Contributing Risk Factors

Brachycephalic breeds like Bulldogs, Pugs, and Shih Tzus are especially vulnerable due to their shortened airways. Other high-risk factors include:

  • Thick double coats (e.g., Golden Retrievers, Huskies)
  • Obesity
  • Senior age
  • Heart or respiratory issues
  • Flat-faced anatomy

In Hong Kong, the dense urban environment can also limit airflow, compounding the risk. Pet parents must exercise caution and provide cool environments for these dogs, especially during walks or outdoor activities.

Emergency First Aid for Heatstroke and When to Seek a Vet Immediately

If your dog shows signs of heatstroke, act fast:

  1. Move to a shaded or air-conditioned space
  2. Offer small amounts of cool (not cold) water
  3. Wet their paws and underarms with room-temperature water
  4. Use a fan to enhance cooling

If symptoms persist after 10 minutes or worsen (e.g., seizures, collapse), go to the vet immediately. Delay can lead to organ failure. Time is critical in treating severe cases. Always follow up even after symptoms subside.
