I used to buy the huge Old Mother Hubbard biscuits for Casey on special occasions. They were wrapped in plastic and she would sit with anticipation while I would peel the plastic off. She would take the biscuit into the living room, throw it on the floor and bark at it. Then she would eat it. I still to this day do not know why she did that. She never did it with any other biscuits, small or large. She is too much of a piggy to go bury them somewhere. She catches the smaller ones mid air and barely chews them.
