A poster with an image of a dog reads in Spanish; "Feed the stray dogs, help them so they do not die. God will reward you!," on a wall in the hilltop borough of Iztapalapa in southeast Mexico City, Tuesday, Jan. 8, 2013. The fatal mauling of four people by feral dogs in a Mexico City park set off debate Tuesday about the city's love/hate relationship with its dog population, and the guilt or innocence of 25 dogs trapped near the scene of the nightmarish killings. Antemio Maya, president of the Street Dog Protection association, estimates for the overall number of dogs in the city of nearly 9 million people range from 1.2 million to 3 million animals.
