Heating and A/C for dog houses in America

[Black Wolf]

I will go to a hunting dog forum and maybe ask there. Most owners of hounds and retrievers keep their dogs kenned outside. They may have climate-controlled provisions for their custom-built dog houses. In North America there can be scorching summer desert heat or winter snow blizzards depending upon where one lives.
I would also have my kennel well-shaded and a wading pool with a drain built in so dogs can take a dip during hot weather.
