Malignant hyperthermia is characterized by abnormally high body temperature and muscle contraction that can potentially lead to death.
It is triggered in susceptible dogs by excitement, apprehension, exercise, or environmental stress.
Giving certain anesthetics or specific drugs that affect the neurologic and muscular systems also consistently triggers malignant hyperthermia in susceptible dogs.
