The last dogs I had were a Weimaraner and a German Wirehaired Pointer, they both were kennelled outside in a shed with run.
Both loved it inside given half a chance though, especially 6" in front of our open fire, sometimes, so near they would "smoke" !
Being an old softy, I had a red heat lamp in their shed though, sort of thing farmers put over piglets.
I did move the whole lot into the back of my garage when the GWP was a pup.
It had a problem (prob GWP related) and burned the whole garage down together with my beautiful red Westfield (dogs were OK though) !
Not sure if the heat lamp was neccessary but made me feel better on really cold nights.
