This is the heartwarming moment a student shared his breakfast with a stray dog in a school in southern Thailand.

The video was taken by teacher, Tle Rutchanon, who was passing by the playground when the sweet moment happened.

Rutchanon said he was moved when student Mongkolsak gave some of his porridge to the dog who was begging him for some food during their break.

In the video, Mongkolsak is seen sharing his breakfast to the hungry dog spoon by spoon until he allowed the poor stray to have the porridge for himself.

Tle said: "I was witnessing the two best friends and curious how the boy would do. It was one of the most adorable moments I have seen since I first started my teaching career."
