I found my girls were not amused at being put in the whelping box on their own so would leave it up to them, as the time got near and I would be pottering around upstairs they would take themselves off and be found napping in there, I would also leave them there over night for the last week and sleep in that bedroom too.
There are some bitches who flatly refuse to whelp in the whelping box and prefer your bed or the sofa, just in case this was to happen to me I buy a supply of ASDA's value range of shower curtains to protect the furnishings, they make ideal carpet protectors for when the pups have more freedom or under the puppy pen.
Here's to a safe and healthy whelping.
