The Hong Kong man known as Jacky Lo, who had earlier put his dog in a spinning washing machine supposedly to bathe his pet, threatened to kill dogs in a Facebook posting, according to Sin Chew Daily.
Lo wrote on Friday that he had six strays with him and the fate of the animals would be tied to the answers given to questions he would be posting every day.
A correct answer will mean the release of a dog while a wrong answer will make him kill a dog.
Lo posted the challenge on the HKGolden.com Chinese discussion forum in retaliation for being exposed online for his dog abuse on Aug 12.
However, his Facebook page was disabled and netizens are now demanding that police act against him.
