Hi im new here my dog is due to give birth on friday it is her 2nd litter,her temperature dropped yesturday
and she began to dig, she started panting shortly after, ive been sitting up all night with her but nothing happened shes still panting but thats it shes fine in herself and is not losing any discharge and the pups are active all seems great except it seems such a long time is this normal? any advice please?

Can be like this for up to 48 hours.  Looks like you've got a full 3 days ahead of you :d  Good luck to you and your girl.
