Dogs are pack animals.
As their owners, we become their substitute pack. A dog separated from the pack is an insecure, nervous animal. Just as nervous and worried people pace and chew on pencils, nervous and worried dogs dig, bark, and chew.

A working farm dog, stock dog, or hunting dog gets lots of interaction with its people and spends the time alone sleeping.
