Grizzer has a great clip on Youtube this week showing him caching a deer leg.  It is amazing to watch a wolf cache, then go home to my pet dog and watch the exact same behavior from pushing with the nose to the tamping motion to make sure it’s covered well.  There’s a lot of new genetic research about the origin of the domestic dog, and whether it is related to current day wolves or wolves that have long been extinct, there is no denying there are some very strong behavioral correlations between our pet and wolves that developed behaviors necessary to survive in the wild.
