A heartwarming video has emerged from China of fire fighters saving a dog that trapped its head in a tiny hole in a wall for more than three hours.

In the footage, captured during the rescue in Anhui Province on Sunday, the rescuers can be seen patting the whimpering dog to calm its nerves before they gradually drill into the wall to extend the hole and let it out.

According to local news, the dog had been trapped for more than three hours but was finally rescued without injuries. While it was believed not a stray, the owner remains unclear.
