DogHouses Outdoors. Relics of the Past

Dogs have moved indoors, for the most part, so what has become of the market for doghouses ? Watching a DIY video about building a Canine Castle (just a nice doghouse) for outdoors use, I realized that my dog wants to be with me, not out in some wood box with cobwebs and bugs. Whose dog lives outdoors anymore ?What is the current market for doghouses these days ? Can they be re-purposed ? And for what use ? Make the doghouse a little large, add wifi, and I will hang out with my dog in a wood box outdoors. Maybe. Depends on reception.
