The bitch will give birth approximately 9 weeks from when she first starts standing for the male dog or 8 weeks from when she stops standing for the male dog. Counting from breeding dates can be a fairly inaccurate method to determining a due date.
There are three stages of labor.
The first stage occurs when the cervix is dilating and there are some uterine contractions. You may notice some shivering, restlessness, panting, vomiting, and unwillingness to eat, and the dog may seek out a private place. If you do notice this stage (which lasts six to 12 hours), encourage your pet to go to the whelping area.
Stages two and three, active labor and placental expulsion conclude with the expulsion of the puppy and the placenta, respectively. If your dog has more than one puppy, she will alternate between stages two and three. Once your dog begins actively straining, the first puppy is usually delivered within 10 to 20 minutes. If the active straining has gone on for an hour unproductively it is time to call the vet. She needs some professional assistance. Many dogs will rest between puppies for an hour or so. This does not require intervention since the dog is not actively straining.
In summary the normal onset of labour is marked by the following events
24 hrs before-bitch may hide and attempt to make a nest
12 hrs before-bitch refuses food. A white vaginal discharge may appear(cervical seal)
12-8 hrs before-bitches rectal temp drops at least 1 degree Celsius to about 37 degrees Celsius.
1 hr before-labor pains begin shortly followed by contractions.
2 puppies are usually delivered in close succession followed by a pause of 1 or 2 hours.
Delivery of the entire litter may take 24 hr
