Thousands apply, but only a select elite few are chosen to serve at the CIA. But even then, sometimes a job so stressful and demanding isn't all that it's cracked up to be.

That seems to be the case for Lulu, a puppy who was a part of the agency's bomb sniffing puppy class.

Lulu was one of six puppies that were selected to undergo 16 weeks of training in order to become some of the CIA's next K9 agents. According to the CIA, the puppies will become, "the first line of defense against explosive threats to Agency personnel and buildings and Headquarters broad."

Unfortunately for Lulu, the life of a CIA agent did not seem to be for her. The agency said that Lulu had simply lost interest in sniffing for explosives.

"Even when they could motivate her with food and play to search, she was clearly not enjoying herself any longer," the CIA wrote.

On Tuesday, the CIA announced that Lulu had "retired" from the program. Lulu now lives with her handler, who adopted her, and is enjoying retirement with Harry — her best canine buddy.
