If you leave your dog outside, a dog house is necessary for shelter from the rain and wind. I have one, but my dog won't go into it - so when he is outside - I even crawled in it - but he still wouldn't go inside. So, I leave the breezeway door open so he can go in there for shelter.
My Sting is a dog house failure, but my other dogs were fine with it. I suggest you take Apoolutz's advice about the bed and location of the dog house. And also put a favorite chew toy inside the dog house.
