My boxers are generally full time indoor dogs. My home has a 75x40 fenced run and the boys have access through a laundry room doggie door. In nicer weather (dry and warmer than 50) they have 24 hour access to that. When it's too hot, they will go out and use the toilet or find a shady tree to lay under, but generally come inside. Spring and Fall you can always find them outside, either lounging or playing. In winter they hate the cold but Max is still young so he'll find any excuse to go play in fresh snow. Even given the choice, the spoiled boys prefer the soft inside furniture to the outdoors.
