“One of the CIA’s most unusual plans for an identity transfer required a big dog. In the 1970s, a plan was conceived to post an officer abroad with an adult male Saint Bernard weighing more than 180 pounds. When identity transfer was needed, the dog would be swapped for an agent concealed in a full Saint Bernard skin and inside a portable kennel.A tape recorder and small speakers hidden in the kennel provided sound effects to enhance the effectiveness of the illusion. The agent-dog would be taken to a safe location for “examination by a veterinarian.” Once inside the safe house, the agent could be safely debriefed, and when the “examination” was completed, he could redon the dog skin, get into the kennel, and be returned “home.”91
