Yup, same here.....watching Garrett eat a biscuit, a kibble or any treat for that matter is VERY entertaining. He picks it up in his mouth, throws it around, flips and dances around it, paws it a couple times....then repeats the sequence a couple times!
It is hilarious...
Sometimes he'll even bark and growl at it too, or run around the house madly with it in his mouth.
I figured it's a Yorkie thing!
