A dog’s pregnancy, also called the gestation period, typically lasts about 63 days (just over 2 months) from conception, though it can vary between 56 and 70 days depending on the individual dog and breed

Key details about dog pregnancy duration:

• The average length is around 63 days.
• Pregnancy length can vary due to factors such as when fertilization actually occurs relative to mating, since sperm can survive several days in the female reproductive tract and eggs take time to mature before fertilization

• This means the exact date of birth can be difficult to predict, with a normal range extending roughly one week before or after the 63-day average

Summary:

• Dogs stay pregnant for about 2 months.
• The gestation period ranges from 56 to 70 days.
• The average is approximately 63 days from conception.

This timeframe is consistent across most breeds, with some natural variation
