Amusing footage of a dog, who is normally a bit of a hunter, getting completely baffled by a tortoise.

The video, filmed in Tulsa, Oklahoma, USA, on February 3, shows the dog barking and squealing at the tortoise, which is hiding inside its shell.

According to the filmer, the dog, called Lucy, has frequently "taken down" squirrels and rabbits but has absolutely no idea what to do with a tortoise.
