Finnish Spitz Kiko can perform the unique trick when told to by owner Ashleigh MacPherson and the pooch has been compared to Linda Blair's character Regan in the film 'The Exorcist' - who left moviegoers terrified with a famous head-spinning scene.

Ashleigh said of the dog: "She has always done it, since she was a small puppy. At first, she started doing it as she slept. I always just thought 'she just likes to sleep broken'.

"I didn't think too much of it, as dogs like to sleep in weird positions, but she began to do it to look at other dogs.

"Instead, of turning her head around like a 'normal' dog she would bend her neck backwards.

"Maybe she loves looking at the world upside down. As we built our bond, she began to do it to keep her focus on me."
