Abstract: The present invention provides an animal shelter suitably adapted for the sheltering of animals under adverse temperatures. The shelter includes an external enclosure, an internal structure within which the animal is housed, an air passageway circumscribing the internal structure which is disposed between the internal structure and the external structure, and a thermal source for heating or cooling the air within the passageway. The thermal source may be thermostatically regulated to provide a controlled habitat environment.
