South Korea’s parliament on Tuesday passed a landmark ban on the production and sales of dog meat, as public calls for a prohibition have grown sharply over concerns about animal rights and the country’s international image.

Some angry dog farmers said they plan to challenge the bill’s constitutionality and hold protest rallies, a sign of continued heated debate over the ban. The bill would make slaughtering, breeding and sales of dog meat for human consumption illegal from 2027 and punishable by 2-3 years in prison. It doesn’t provide any penalties for eating dog meat.
