A Siberian Husky has almost managed to escape from the pet hospital that shelters it in east China's Jiangsu Province.
Surveillance video shows the dog pried the cage door open with its tongue and teeth. The sled-puller then started to work on the room door, but it was protected by a password.
The persistent dog quickly took the more forceful approach of tearing down the door, spooking the cats in nearby cages.
After unsuccessful attempt the dog opened another two cages to let out two large dogs.
