This is the heartwarming moment a dog was rescued after being trapped in an eight metre deep abandoned well for four days.

Farmers were working on a rubber tree farm when they heard the pooch howling in Trang, southern Thailand on Monday (September 14). They followed the crying sound which led them to a dried up well nearby.

The dog's owner, Nanthicha Chuphlu, 29, also arrived at the scene when neighbours informed her that a trapped dog had been found.

The worried pet lover said she was looking for her lost three-year-old dog after it had been missing from home for four days.

She said: "I am thankful to the farmers because they did not ignore my dog crying. She could have starved down there."

The Bantao Wiset rescue team led by the head Apichat Wangsud rushed to the farm with full-handed gears and ropes after the farmers called them for help.

They tied a noose around the dog's body and pulled it up. The dog was finally reunited with its owner after half an hour.

The weary animal was given food and water by the rescuers before it played with them as if it was saying thank you.

Head volunteer Apichat said: "We were called for help and we tried our best to help it because the well was too deep and steep. We were glad that it was not harmed after days of being trapped in the hole."

The dog went home with its owner who was grateful to the rescuers for helping her pet.
