You might find it a good idea to put down a tarpaulin or dust sheets in the room where the pups and Mum are.
I've just moved my pups (3 weeks) and Mum into the kitchen (tiled floor) where the rest of the dogs are, so they can have a larger pen.
While she was in the living room I covered the sofa in a doubled bedspread and fortunately the floor is laminate with mats.
Mum is of course giving the other girls the hairy eyeball and grumping at them if they look as if they are going to look at the pups :) All bar one have been there done that and got the tee-shirt so aren't that interested. They are jsut more interested when the pusp are fed (on four meals a day eating like gluttons).
Surprisingly silly youngster has minded her p's and Q's and resisted the temptation to get in with them. Another few days and she will lighten up and say come and see the babies and how clever I am.
