Yep, Gracie Ruth and Yogi do this. The Stare Down, then Charge, Attack, Kill, Escape, Run, Chase, Tag, Turn Run, Separate and Repeat. They will also start with the staring and then s..l..o..w..l..y creep towards each other until they are actually touching nose to nose then total chaos erupts as the rear up and fight like the savage wild beasts Yorkies really are (in their own minds).
We have actually turned off a movie to watch them play this. It is hysterical.
