Section: Overview
Heat stroke is a condition arising from extremely high body temperature (rectal temperature of 105 to 110 degrees Fahrenheit), which leads to nervous system abnormalities that may include lethargy, weakness, collapse or coma. Abnormally high body temperature (also called hyperthermia) develops after increased muscular activity with impaired ability to give off heat due to high heat and humidity or respiratory obstruction. Allowing a dog to remain in a car with closed windows on a hot summer day is probably the most common cause of heat stroke.Normal dogs dissipate heat from their skin. In addition, panting allows evaporation of water from the respiratory tract and is an effective method of heat dissipation. When these mechanisms are overwhelmed, hyperthermia and heat stroke usually develop. The elevation in body temperature stimulates the body to release substances that activate inflammation.
Exercise is as important for your dog as it is for you. Young dogs need a regular daily workout to maintain their physical and emotional health. Learn about basic recommendations.
If your dog suffers an acute collapse, he will sit down suddenly or lie down and won’t be able to get back up. He may even lose consciousness. Call or take your pet to your veterinarian immediately.
