Dozer carries his around while he's chasing the kids on their snowmobiles. He also just lays there with it guarding it form Chloe!
Chloe, on the other hand, buries her bones. She sneaks and lurks around for a long time and when she thinks no one is looking she buries it!
I have seen her re-dig it up a couple of times and re-locate the prized bone.
Needless to say, she has since stole Dozers bone and buried it as well!
Have a wonderful New Years!
