Just curious

I am just curious if anyone else's BT does this.... Recently Kermie has been hiding her treats and her favorite toys. She takes them and places them in strange places around the house, and about 15 minutes later, goes and finds it and hides it again. I have found things under beds, under my dresser, next to movies, behind the couch, under the Christmas tree skirt, even in a place of laundry by the washer! It is so funny and cute to see her try and scout the perfect place. (except when she does this at my mom's house and we are trying to leave and spend 20 minutes trying to find where she hid her new bone!!) My previous dog, a cocker spaniel, never did this. Just wondering is it a BT thing...
