An animal warming enclosure which is suitable for enclosing large animals, such as newborn calves, and protecting them during inclimate weather. The enclosure can be mounted on a vehicle, such as a truck, and the animal will be transported while other chores are completed. The animal will remain warm and can be returned to an appropriate location, such as a barn, when the chores are completed. The enclosure is fluidically connected to the exhaust system of the vehicle so that warm exhaust is used to provide heat for the enclosure.
