Sniffing dogs are being trained to detect cancer in urine

A small Japanese city is set to use a unique method to help cancer patients.

WBAL TV in Baltimore reports that Kaneyama, a town of about 2,200 people, will be the home for a group of dogs that can detect cancer in humans by sniffing urine.

Specially trained dogs can smell odors that humans can’t detect and it has been reported that the dogs used in the exercise have been extremely accurate.

It’s an expensive science, though. It can cost about $45,000 to train each dog.
