Dogs are pregnant for about two months, with the typical gestation period ranging from 57 to 72 days, and an average of around 63 days from conception or ovulation
. This duration can vary slightly depending on the individual dog and the timing of fertilization since sperm can survive in the female reproductive tract for several days and eggs take time to mature after ovulation
. The pregnancy timeline includes three trimesters of about 21 days each
. Early pregnancy signs are often subtle, including pinker nipples and slight behavioral changes, while more obvious signs like weight gain, increased appetite, and visible puppy movement appear in the later stages
. In summary, expect a dog’s pregnancy to last roughly 9 weeks, with some natural variation between about 8 to 10 weeks depending on the exact timing of fertilization and other factors
