A vengeful neighbour took revenge on a pet dog that bit his nephew by allegedly killing the pooch and then eating it.

Songwut Chueathong, 42, allegedly strangled the 10-month-old dog named Chao Mon and then ate it with his friend after the canine snapped at his nephew, 7, in Chiang Mai province, Thailand, on April 29.

Disturbing CCTV footage shows Songwut in his neighbour's yard, dragging the whimpering dog over to a tree using a rope tied around its neck.

He then hanged the helpless pooch until it died, with the brutal act unfolding in front of the young boy.

Songwut was seen hauling the lifeless Chao Mon into a sack and onto his motorcycle.

The Watchdog Thailand Foundation filed a complaint against Songwut and submitted the CCTV footage as evidence following a report from another local in the neighbourhood.

Police Lieutenant Colonel Santi Sekha of the San Kamphaeng Police Station said Songwut was arrested at his home on May 1.

The man allegedly admitted to killing the dog, but initially refused to disclose where and how he disposed of its corpse.

Officers searched the premises and found a bloodied sack, and a large knife believed to have been used to butcher Chao Mon.

Inside Songwut's fridge were several plastic bags of dog meat. Police later found the remaining decomposing dog parts in the backyard.

Songwut claimed he killed Chao Mon 'out of anger' for biting his beloved nephew, then shared its meat with his friend Roj.

He said Chao Mon used to be his pet dog, which he gave away to his neighbouring relative, because he was unable to provide for it.

He said: 'I did not think I would be arrested and charged for killing my own pet dog.'

Police Lieutenant Colonel Santi said: 'The man and his friend are facing charges of committing theft using a vehicle, dumping an animal carcass in a public place, and committing cruelty on animals or killing them. We have seized evidence and are preparing to prosecute the suspects.'

Under Section 20 of Thailand's Animal Cruelty Prevention and Welfare Act, Songwut may be punished with a fine of up to 40,000 THB (865 GBP), imprisonment of up to two years, or both.
