A Detector Dog Training Center that produces numerous drug detection dogs.
Bonggu, born and raised here, is the top student at the center.
Despite being smaller than his siblings, he had an exceptionally great sense of smell.
Bonggu, who could find any drug precisely, was valuable to the center.
However, one day, Bonggu made his first mistake.
He started sniffing for drug scents in bags without drugs
and couldn't smell his favorite toy dummy anymore.
Detector dogs retire when their senses dull as they age.
However, Bonggu was still too young for retirement.
Why did Bonggu keep making mistakes?

A brief piece of common sense about detection dogs!

Detection dog training centers use towelmade toys called "Dummy."
Dummies are infused with drug scents for dogs to train to find them.
When a dog finds a dummy, handlers play and praise them, making drug detection seem like a fun game.
There's no need to worry about drug exposure for drug detector dogs!
Just sniffing doesn't affect the dog at all!
