I use a plastic sweater box and place towels inside for the bitch to nest. Once she is actually pushing etc... I replace the towels with washable pee pads and exchange for a new one after each pup is born.
Once the litter has arrived, I place a heating pad in the bottom covered with a crate pad.
Not sure when the pups are due but you may wish to buy Myra Savant's books. They are a god-send.
