When his dog went missing, Wang Yan searched everywhere - even the slaughterhouse in his town in China.
"I went looking everywhere, but all to no avail," Yan remembers, according to The Shanghaiist. "Finally someone let me go into the slaughterhouse to try my luck there."
Even though he never found his dog, Yan found his true calling. The pain and suffering he witnessed at the dog slaughterhouse back in 2012 was enough to change the whole course of the 29-year-old's life.
