Typically the gestational period of a female dog lasts around 65 days. The signs of whelping can differ between breeds, but there are many signs that are generally universal and will be noticed in the days leading up to the birth. It is important to watch for these signs so you can assist your dog in the birthing process.

First Stage
-
If you have been monitoring your dog̵7;s temperature, it will drop to around 98 degrees when she is getting ready to birth her puppies. A normal dog̵7;s temp is anywhere between 99-101 degrees. Your dog will also seem restless and not be able to find a comfortable position. She may also lie on her side quite a bit. She may also vomit, urinate more frequently, refuse food and water, and feel the need to have you constantly at her side. Your dog will also have a swollen vulva and a mucus discharge. This is also the point where she will search for a quiet place such as underneath the bed or her whelping box, if one is provided.
Second Stage
-
Your dog will now find her way more permanently to her whelping area and begin to move around any towels or blankets that may be found there. This is nesting, and a sign she is readying the area for her pups. Watch for shivering and panting; your dog may begin to lick her vulva and keep a watchful eye on her rear end. This practice will continue throughout her labor. You may notice a few mild contractions along with more vomiting, urinating and defecating.
Third Stage
-
The wiggling, digging and panting will intensify as she prepares for the birth of the puppies. The contractions will become stronger and closer together. You will recognize the signs of a contraction because your dog will begin to move her legs and making a whining noise. She will also begin to push at this point, and will grunt and possibly continue to vomit. Pushing will begin and will generally last for anywhere from 2 to 10 minutes. The first puppy will be birthed at this point.
