Panorama: Dogfighting Undercover

Investigation into the secret and dangerous world of international dogfighting. For a year and a half, a BBC undercover team operated alongside dogfighting gangs in the UK and Europe, capturing on camera the savagery of organised fights. The film also reveals how American pitbull terriers - a banned breed created to be the ultimate canine gladiator - have been sold by the gangs into inner city Britain.
