Canyon Mansfield of Pocatello%2C Idaho was 14 years old when he watched his Labrador%2C Kasey%2C stumble upon a %22cyanide bomb%22 known as an M-44 near his home and then die right in front of his eyes. Casey%2C too%2C was put in grave danger. His family has become national advocates for reforming Wildlife Services and getting a ban on biocides in place. Photo courtesy Mansfield family
