Sickening footage shows a woman stubbing out a cigarette in the eye of a defenceless puppy.
The dog’s mouth appears to be taped shut, stiffing its yelps as the culprit repeatedly burns the dog’s face.
She calmly smokes with one hand while holding the puppy by the neck and snaps its paws after she is finished.
The Society for the Prevention of Cruelty to Animals in Singapore was alerted last month to the sadistic video.
The animal welfare group is now appealing for help to identify the woman after initial claims she was filmed in Singapore or another country in the region.
Members believe the video was made by ‘syndicates that profit from animal torture films, including some that are produced for sexual fetish.’
They said in a statement: ‘There are indications that the incident may not have occurred in Singapore but we are exploring all possibilities and urgently appealing for credible information to seek justice for the puppy.
‘If you know the identity and whereabouts of the woman, please provide the information to the relevant agency in your country.
‘Alternatively, you can contact us and we will relay the message in strict confidence. Let us stand united against animal cruelty, wherever it may occur.’
Indonesian animal rights activist Carla Day started a petition which she shared on social media in a bid to trace the woman.
She said: ‘The innocent black-and-white puppy has their mouth tied shut, completely helpless against the agonising torture.
‘This shocking incident cannot be ignored, or more animals will be tortured or killed.’
Filmed in 2012, the video was created by Dorma and Vicente Ridon, a married couple who were found guilty of child abuse, animal welfare crimes, human trafficking, and wildlife-protection crimes in a Philippines court in 2014.
