Dogs are susceptible to heat stroke even at moderate temperatures, especially in cars and during exercise. Understanding prevention and early recognition of heat stress is critical for dog welfare in warm weather.
Heat stroke causes immense suffering and death in dogs who depend on their owners to keep them safe in warm weather. A dog left in a car on a warm day does not simply feel uncomfortable - it experiences progressive organ failure from hyperthermia that causes brain damage, blood clotting disorders, and multiple organ failure within minutes. Dogs exercised vigorously in hot weather face the same risks. The responsibility for preventing heat injury lies entirely with the owner - dogs cannot remove themselves from dangerous situations. Simple rules - never leave dogs in cars, exercise in cool parts of the day, provide shade and water always - prevent almost all heat casualties.
