A vendor cuts dog meat for sale at his roadside stall in Duong Noi village, outside Hanoi December 16, 2011. While animal rights activists have condemned eating dog meat as cruel treatment of the animals, it is still an accepted popular delicacy for some Vietnamese, as well in some other Asian countries. Duong Noi is well-known as a dog-meat village, where hundreds of dogs are killed each day for sale as popular traditional food. Dog-eating as a custom is rooted in Vietnam and was developed as a result of poverty. One kilogram of dog meat costs about 130,000 dongs ($6.2). REUTERS/Kham (VIETNAM - Tags: ANIMALS SOCIETY FOOD) 

Two snakes are seen inside their compartment in wooden cupboards labelled "Poisonous Snakes", at a snake soup store in Hong Kong January 29, 2013.
