Quote from CNN's article written by Arwa Damon :
The last dog culling in Baghdad took place before the U.S.-led invasion in 2003. Since then, the stray dog population increased dramatically and became a threat to humans, authorities said.
Some Iraqis say that in areas where the sectarian killing was high and bodies lined the streets, the dogs became used to eating human flesh.
An Iraqi veterinarian said that makes the strays more aggressive toward humans.
Students at a girls' high school in Baghdad welcomed the culling teams, saying the dogs had become a menace.
"They would attack us in the morning when we were on our way to school," student Hanan Sami said. "Not just one but packs of them."
The girl said she has a pet dog and loves animals, but said the strays have to be dealt with.
Headmistress Mahassen Youniss said critics of the culling program should consider human rights before animal rights.
