A lion and a miniature dachshund have formed an unlikely friendship after the little dog took the king of the jungle under his wing as a cub.

Bonedigger, a five-year old male lion, and Milo, a seven-year old Dachshund, are so close that Milo helps the lion clean his teeth after dinner.

The 500 lbs lion dwarfs little Milo, yet after the dog took the disabled lion into his protection as a cub, Bonedigger has rarely left his side.

It was filmed at a zoo in Wynnewood, Oklahoma.  (About 60 miles south of Oklahoma City.)  They've apparently been best friends ever since Bonedigger was born five years ago.

Bonedigger was born with a metabolic bone disease that left him mildly crippled.
