When Johnny Mathis of Houston, Texas stepped out of the lift in his apartment block, he didn’t know he would soon be saving the life of his neighbour’s dog. CCTV footage of the dramatic incident, posted on social media by Mathis, shows the moments that led up to the rescue as well.

Mathis was exiting the lift as a woman with her dog on a leash was entering. However, the lift doors closed on the dog’s leash, leaving him outside. As the lift began to move, Mathis turned back just in time and rushed to the canine’s rescue.
