Dog won't sleep in the dog house

Now I have a husky/shepherd mix male that will stay outside as long as we let him, no matter how hot or cold it is. He lies on the concrete patio in the direct sun when it's 95*, not a care in the world. My female shepherd/husky mix prefers being in the house with the a/c in the summer and outside in the winter.
Dogs, gotta love 'em.
