A sick puppy managed to escape her cage while being kept overnight in a vets office leaving quite the mess in the morning for staff to clean up.

Somehow the cute pup was able to get out of her container and began running around and jumping all over the small office.

By the time morning came around, the vet open the door to the office and found chaos.

A dog that had been left in a vet's office overnight managed to escape its cage

It looked as though the place had been ransacked with papers, boxes and various other objects strewn about the floor.

The cage door appeared to have been flung wide open, and then as the camera panned upwards, the culprit was revealed.

An innocent-looking black and white dog could be seen peering down from the top shelf.

'Oh hey here! Whatcha doin'?' asks the vet as she opens the door. The dog looks on coyly.

'She was not hurt, very scared but very sweet. She was able to come down and snuggle with one of the techs,' the vet wrote in the YouTube posting.

The chaos was only discovered the following morning when the worker came in when the little pet was found sitting on the top shelf looking completely innocent

'She is happy and healthy. Her situation helped us make sure it never happens again to keep other patients safe. One of a kind patient. So glad I was able to help her getting feeling better and able to get her to trust me. The cage was chained but she was smarter than the cage and apparently the staff!'

The video generated some amusing comments from online users.

'Didin do nuttin'' wrote one viewer.

'Whaddya mean what am I doin' ? I'm trying to avoid getting torn to pieces by the Monster that made this mess...' wrote another, in a witty attempt to explain the dog's behavior.
