Lion has a new best friend

A zoo keeper catches a feline and a canine making friends...and the video goes viral.

Staff at a zoo in Oklahoma catch the moment a male lion and a small dog share what looks like a kiss in their compound.

"Milo" the Dachshund can be seen trying to lick "Bonedigger" in the lion's face.

The zoo keeper says the unlikely pair have been inseparable since they met - and now share a compound at the zoo.
