"Animal Planet Investigates" is a series of quarterly one-hour specials that takes a comprehensive, investigative look at timely issues that impact both humans and animals. This program uses interviews and never-released undercover and investigation footage to cover topics such as: dogfighting, animal testing, the exotic pet trade, cloning, pet food nutrition, and slaughterhouses. The first special goes deep into the secretive world of organized dog fighting with two cops, who re-live their time dealing with hardcore criminals, big bucks gambling and almost unimaginable cruelty after spending over two years undercover as dog fighters.
