A family was left terrified when they spotted a snake emerging outside their home.

CCTV footage shows the Oriental Rat Snake slithering across the grassy yard toward a shoe rack placed next to a door in Udon Thani, Thailand.

Moments later, an elderly man carrying a grass cutter walked into the house and placed the equipment inside on July 7.

He can be seen stepping back outside, unaware of the danger lurking inches away from his feet.

The pensioner then closed the door just as the seemingly startled reptile attempted to crawl inside.

As the man moved away, the women heading to the house pointed out the snake in the doorway, prompting him to turn around.

Upon seeing this, their pet brown dog immediately sprinted toward the escaping snake.

However, the serpent managed to flee, squeezing under a broken cooler nearby before creeping out of the area to safety.

The Oriental Rat Snake is a non-venomous species that can grow up to 6.6 ft (2 m) in length.
