Pups spend the first 5 weeks developing and don't grow alot until the last 4 weeks. Because you bred for such a long time it will be harder to pinpoint the day of conception. She would be due after the 24th of Sept. FYI because sperm is viable for 48 hours it is advisable to only breed once every other day for 2 or 3 times. Any more than that is an unnecessary drain on the male. Some breeders believe that too many matings can abort any ova already fertilized; others believe that it might be responsible for the resorption of the whelp by the dam. If your gal is pregnant she should show weight gain after the first five weeks and the movement of the pups should be felt after 7 weeks.
