To boost their popularity, several presidential hopefuls have pledged to ban dog meat in recent weeks, especially as dogs have become popular as pets and advocacy groups have urged South Korea to close down restaurants and markets selling dog meat.
Lee Jae-myung, governor of the country's most populous province of Gyeonggi and a leading presidential contender from Moon's party, has vowed to push for a ban through social consensus.
But Yoon Seok-youl, an opposition front-runner, has said it was a matter of people's personal choice.
A poll commissioned by animal welfare group Aware released this month said 78% of respondents believed the production and sale of dog and cat meat should be prohibited and 49% supported a consumption ban.
But, another survey by polling firm Realmeter found people were divided over whether the government should ban eating dog meat, though 59% supported legal restrictions on dog slaughter for human consumption.
Dog meat sellers have insisted on the Right to their occupation, saying their livelihoods are at risk.
