Isabel's breeder used a baby playpen. Half was set up for sleeping half was set up for paper training. When we first brought her home we also used a playpen (she was so small even at 13 weeks) and this seemed to scale down for her the idea of "where" to do her business. A big house can be overwhelming to such a small puppy.
