This is something you may have never seen, and may never see again. This is the story and video of Bonedigger the full-grown lion, and Milo the weenie dog.

The video is from the zoo in Wynnewood Oklahoma. Milo is a 7-year-old Dachsund and Bonedigger is a full grown lion. The two have been best friends since Bonedigger was born five years ago. All of his life, Milo has licked his teeth clean daily.
