The gestation period for all dogs big or small is about 9 weeks. It's a short amount of time so it will go by quickly. Make sure the area where the dog is going to whelp is ready plenty of time before she goes into labor.
No matter what type of dog you have the gestation or pregnancy length of dogs is 60-64 days. If your dog is already pregnant you will need to know the date your dog mated to determine when the puppies are due.
