My huskies used to be inside all the time, only outside to go potty and for walks. During colder times though they loved it outside and getting them in was a pain. After I had my son though they were pretty much outside dogs. The two I have now are outside the majority of the time still. The one is still a puppy and trying to keep an eye on him and my 2 year old is pretty hard for me to do at the moment.
I hate dogs being outside like that though. I go out there everyday though, and spend a few hours with them and any time I get the chance. Whenever I have free time I usually let them in for awhile. They have free roam of the yard, and it's a very large backyard with tons of shade and a kiddie pool for them when it was hotter out. They also can come inside to our Florida room for shelter though whenever they want.
