We raise Great Danes, and our dogs are usually outside during the day (weather permitting) and inside with us at night. They are allowed in all rooms of the house, but not on the furniture, as they tend to take it over! Though I know that there are certain breeds that actually prefer living primarily outdoors, most dogs would rather to be part of their human pack. I would never sell a puppy to a family who told me they planned to keep it as an outdoor only dog.
