I put a pad just outside her x-pen close to the one inside. I left the door open.
For a while she would go inside the pen to potty. We have wood floors in the living room. After we took down the pen, she was not confused. We kept her bed and all her toys in the same place. She does get confused in the bedroom tho. We have carpet and she sometimes will go on there. I put down 3 pads in there. She is doing well. She is 17 months old now and runs the house. At night she sleeps in her puppy apartment. Naps during the day with me. She does follow me everywhere I go. When we go out, she just lies in her bed until we get home. Such a good girl....
