Well, I have never had normal dogs and one of them refuses to sleep in the dog house that is outside.  She also refuses to sleep indoors, and we have to force her into the garage during bad weather.  We rescued her from a shelter, and I think that a lot of her "eccentric" behavior has to do with what she was used to at one time.  So, in my search for the perfect outdoor bed, I saw a picture for a dog bed on Ana White's website that inspired me.  There were no actual plans for the project, so I created my own.  I actually decided to make the sides higher to help block out some of the weather since she refuses to be enclosed:)
