i'm not one for leaving a dog outside in a kennel or not.
if you build a kennel make sure the dog can't climb out,
dig out, jump out and make sure he/she can't open the
kennel door. the dog box/house she provide some protection
against the weather. i would have something blocking 1/2
of the door so the wind can't blow directly in. across the
the entrance there would be an L shape laying on it's back
across the entrance. heat would really be nice. don't forget
bedding or a raised bed with bedding.
