Expert: Jane Lefler replied 9 years ago. HiCustomer. Female dogs start lactating about a week or so before delivery. A dogâs gestational period (pregnancy) is approximately 63 days from breeding. One way of knowing when your dog with have her puppies is to take her temperature twice daily at the same time each day as her due date gets close. Keep a record of this.
