What is the gestation period of a gray wolf?

The gestation period of a gray wolf is about 63 days. That is the standard quiz answer for the time between conception and birth, although studies and field observations show that the exact period can vary by several days.

Gray wolves usually mate in late winter, commonly around February in the Northern Hemisphere. Pups are then born in spring, when improving weather and seasonal prey availability give the mother and her litter better odds of survival. The female gives birth in a den, which may be a natural cavity, an enlarged burrow, or another sheltered site.

A wolf's gestation is close to that of a domestic dog because dogs descended from gray wolves. The mother generally gives birth to several pups, often four to six, and the newborns are blind, deaf, and unable to regulate their body temperature effectively.

The mother stays close to the den during the first weeks while other pack members help provide food. Pups begin emerging after roughly three weeks, but they continue relying on adults for feeding, protection, and instruction for months.
