My 2 15 wk old puppies do not get the run of the house. There are rooms they have never seen yet, someday they will but that is a privilage they must earn
I have 2 gates up that I use to keep them contained in the kitchen/dining room where I have hardwood laminate flooring (easy to clean up) After school and work that is where most of the action is- someone is always in the kitchen so they don't feel lonely or neglected...
After dinner, when every is going into the family room to watch TV or use the computer they get to come in there with us, but then they still only have the run of the kitchen/dining room and family room.
