How long are dogs pregnant for?

The duration of a dog's pregnancy, also known as the gestation period, is generally around two months, but it can vary slightly. Here are the key points:

• The average dog pregnancy lasts approximately 63 days from ovulation, which is just over two months345.
• The gestation period can range from 56 to 70 days, depending on various factors such as breed and litter size145.
• Predicting the exact due date can be challenging because the date of breeding may not coincide with the date of conception. The male dog's sperm can survive for several days in the female reproductive tract, and the female dog may accept mating before or after ovulation345.

Overall, while 63 days is the average, the actual pregnancy duration can vary between 57 to 72 days.
