Wolf pups are generally born in mid April. Gestation period is about 63 days for wolf pups.  At birth they weigh only one pound, and their eyes are closed. At 12 to 15 days after they open their eyes and at two weeks the pups can walk. At three weeks the pups come out of the den for the first time. 

 

Wolf pups are born with blue eyes. At sixteen weeks their eye color changes to a yellow-gold. It’s rare but some wolves will have blue eyes. 

From pup to adult member of the pack 
10 – 13 days: the eyes open

Three weeks: pups explore their den

  

Four to five weeks: pups take short trips outside the den and the pups start to eat regurgitated meat from the adults

Six weeks: pups will travel around the den but not far

Six to eight weeks: pups are weaned and stay at a rendezvous site with a babysitter, usually older sibling

12 weeks: pups go on hunts with the pack

Life in the wild is not easy

Mortality for wolf pups is around 45% and pups are preyed upon by Eagles and bears. Wolf pups often die from starvation and malnutrition. 
 

Wolf pups are raised within a closely nit family called a pack. Wolf pups quickly earn or learn their status within a pack. The wolf family is led by an alpha pair. Pups are taught how to hunt by the pack members.
