A Polish film maker's short horror film featuring his pet dog in a tarantula costume was the biggest "trending" video on YouTube in 2014, parent company Google has announced.

With over 113m views since it was posted in September, Mutant Giant Spider Dog was the most shared and discussed online, according to YouTube.

In one scene, a man taking out his rubbish flees for his life when Chica emerges from behind a door, while in another, two girls scream and run after seeing the creature atop a lifeless man in an elevator.

Later in the video, a couple spot a flinching man wrapped up in a 'spider web' hanging from a tree in a park and the man bravely creeps towards it, while his girlfriend stays rooted in her position.
