The term 'Wolf, in Juarez' is a reference to the Mexican wolf, or LOBO, which is native to the Chihuahuan Desert region of Mexico and the southwestern United States. The Mexican wolf is the smallest subspecies of gray wolf and is listed as an endangered species. It is believed that the Mexican wolf population in the wild has been reduced to fewer than 300 individuals. The Mexican wolf is found primarily in the state of Chihuahua, including the city of Juarez.
