fric·tion burn(frikshŭn bŭrn)
An injury caused by rubbing against a rough surface, which removes layers of the skin.
injury to tissues caused by contact with dry heat (fire), moist heat (steam or liquid), chemicals, electricity, lightning or radiation. The damage done by a burn includes shock due to the tissue damage, severe dehydration due to the loss of the protective effect of the skin, infection of the burn site, damage to lungs and eyes by exposure to high temperatures and smoke and debris, damage to external somatic addenda including vulva, teats, prepuce, scrotum. The critical decision in a burn case is whether to allow the animal a faint chance of recovery and therefore to continue with treatment. See also bushfire injury.
the skin is damaged by the heat created by friction as by a rope burn, or when a dog is dragged by its lead behind a car.
