Milk production in dogs is started towards the end of gestation or at the advance stages of pregnancy. Usually milk is produced at the end of 8th week of pregnancy in dogs. So, there is possibility that your dog may deliver puppies within one week.
In some dogs, milk is produced 2-3 days before delivery, so you should not rely on the milk production in your dog to know expected date of delivery. You should get abdominal ultrasound which will help you in knowing expected date of delivery and possible litter size. So, it will be better to get help from the vet.
