The puppies have today moved into a more 'open-plan' living environment, with the whelping box inside a pen, in a room that adjoins the sitting room. At the moment the pen area outside the box is just a small space of newspaper-filled tray to encourage them to use this part as a loo. Once they are accustomed to this and more active, the area can be extended to give them a separate playing and eating space also.
The pen has a gate blocked off with a piece of cardboard so Pasha can come and go as she likes, and the puppies can see into the living room and the other dogs. The doorway to the room also has a gate on it so it's possible to shut Pasha in there and the other dogs out.
