Breeding - What to expect after mating. Pregnancy, also called the gestation period, normally ranges from 58 to 65 days with an average of 63 days. With a planned breeding, the date of mating should be carefully recorded. If there are two matings, make a note of the exact dates and expect birth to occur between 63 and 65 days later. Immediately after your female dog has been mated, is there anything you should do? Make sure that she does not have the opportunity to mate with any other dogs. Remember that oestrus will continue for several more days and she could theoretically become pregnant from another dog during this period.
Most dogs are pregnant for between 58 days and 64 days. The due date varies slightly depending on the breed and size of dog as well as the size of the litter she is carrying, but vast majority of dogs will give birth on the 63rd day. If you know the date your female dog mated, you can count 63 days from that date
