The rule of thumb with any dog or breed is that the larger the dog, the more space it needs for exercise (A Saint Bernard cannot be expected to get proper exercise inside a one-bedroom shack, for example).

Some people equally share the inside and outside with their dogs and usually end up getting a doggy door installed so their dog can come and go as it pleases. Other people prefer to keep their dog inside only and just take their dog on walks and let it run free at dog parks. Then, there are those people that keep their dog strictly outside regularly.

Larger and medium-sized dogs do best when permitted to spend their days outside and their nights inside (or outside in a properly-built doghouse). Smaller dogs prefer to be inside at all times and close to their owners and where it is warm (smaller dogs have much more difficulty regulating their body temperatures).
