My three are inside/outside--they have a doggy door and a 6 foot wooden fence all around. When I have accidentally left the panel in the doggy door all day, they were grateful to get out but didn't do any damage inside. And no puddles.

Bella is part chow and would be happy to stay outside. She lived in the woods for a couple of years so she knows she's got it good now.

I really don't like to see dogs tied out for long periods. I can understand that some will jump fences, dig under, or just plain destroy the yard, but I'd rather see other steps taken to keep them home while the owner works. When the owner is home, the dog should be with them. And of course there are always exceptions, like the sheep herding dogs.
