Avalanche is a 220 lb English Mastiff and Hurricane is a 7 mo Mastiff.  They live on a very busy road and are escape artists.  They have a small kennel quite a ways from the house where the owner puts them as she travels for work.  They were tied to a covered porch but would get tangled around the posts.  The fence would open into a secured closed garage where they could come in out of the winter weather and the summer heat.  No dog houses are necesssary.
