A pet can be burned by caustic chemicals, electric shock, or contact with an open flame or a hot object. You may notice dark, discolored fur with a burnt odor, or you may actually see the swollen, blistered skin underneath. Electrical burns are the most dangerous and can cause heart failure. An animal that's been shocked should be covered with blankets or coats and taken to a veterinarian immediately. Heat burns should be flushed with running water from a hose or shower for at least 15 minutes. If this isn't possible, gently place a cool, wet cloth on the burn site. Never put oils or greasy ointments on a burn. If large amounts of dry chemicals are on the skin, brush them off before flushing with water. Seek veterinary care right away. Another potential danger for pets is heat stroke, a dangerous increase in body temperature. Most often, this occurs on a warm day when the animal is left in a car or exercises too vigorously. Signs of heat stroke include heavy panting, gasping, vomiting, skin that's unusually warm, drooling, and bluish gums. Get your pet into the shade immediately and place it in cool, not cold, water or cover the animal with wet towels, then seek emergency care as soon as possible.
