Hi as you said she may become restless, she mite look for a place to have her puppys she may start to dig up in your house or garden . if you start takeing her temp you you may notice a sudden drop to around 37.3 if this happen she should go into labour with in 24 hours, but remember as its her first litter it can take 2-3 day before she whelps , keep a cool head on you shoulders and just be there for her warm regards debbie.
Hi Sharon, my girls usually become more restless. going in & out of the whelping box doing a bit of digging & tearing the newspapers , in & out to the garden as if their busting for a wee, but only doing a dribble !! this can go on for up to 24hrs before they take to the whelp box and the ripping the paper with their teeth starts , with resting in between , then they usually start pushing within a few hours . ooh i bet your so excited !!! good luck to your girl & you , let us know how she goes on :):)
