With temperatures reaching an overnight low of -27 degrees, we added a few extra food resources in addition to the Retired Wolves morning breakfast of 3-4 pounds of meat.  In this image, Grizzer manages to keep a deer leg from Denali and proudly carries it through the pack holding area.  While we have plenty of thick straw beds and covered spaces for the wolves to curl up on a cold winter night, there is an advantage to keeping them active with good circulation to their extremities.  The extra food resources encourage activity, competition and extra calories as well as keeping Grizzer’s mind alert.
