Here is the room, fence and dog doors that we have built onto the house, so the dogs can come & go as they please. We leave the dog room open to the rest of the house, unless for some reason they require to be closed in their room. Look closely at the the picture of the 2 dogs in front of the dog door and you'll will see Merry's head & tongue sticking out of the dog door.

We have 6 acres of land surrounding the house and when I am home, they can run with me around the yard. We have an invisible fence, so the dogs never get into the driveways or the road.
