How can I tell when my dog is ready to give birth?
How long has it been since she was tied to the male dog. 63 days is a good est. from that day. If you do not know the date. Watch for signs of discharge, nesting and start taking a rectal temp. Normal is 102 if it drops to 98 or 97 get ready to have puppies.
Also if she is arching her back she is having a contaction.
anywhere from 50 - 60 days.
