Heat tolerance
Also known as: Heat intolerance · Hitzeunverträglichkeit · Thermoregulatory dysfunction · Heat sensitivity · Hitzesensitivität
Overview
What it is
Heat tolerance is a metabolic and homeostatic trait that determines how effectively a dog's body regulates its internal core temperature in warm environments. When this regulation fails, the metabolic system cannot balance heat production with heat loss, often involving the respiratory and cardiovascular systems. This complex genetic trait influences how efficiently a dog can cool itself down to prevent overheating.
How it presents
Owners will notice excessive panting, heavy drooling, extreme lethargy, and rapid exhaustion during warm weather or mild exercise. These signs of heat sensitivity can become apparent at any age, often starting in puppyhood or young adulthood as the dog is first exposed to warm seasons.
Treatment
While reduced heat tolerance cannot be cured, it is managed lifelong through environmental adjustments like air conditioning, shade, and restricted exercise during hot periods. Emergency veterinary care for heat-related distress or heatstroke can cost between 100 and 2,500 EUR depending on the severity.
