Based near Bangalore, Chloe and her companions—mostly Beagles and Belgian Malinois—are equipped with harnesses and helmets containing high-tech sensors to aid in this mission. The dogs are trained to identify microscopic odors associated with various cancers in human breath.
The testing involves patients breathing into a cotton mask for about ten minutes, which is then analyzed by the dogs on specially designed platforms. Remarkably, these canines can screen thousands of samples within an hour. A study in the Journal of Clinical Oncology highlights the potential of this method, showing it can accurately identify seven types of cancer with 90% precision.
Ensuring the well-being of the dogs is a top priority. They work only 30 to 45 minutes each day, engaging in an enjoyable game-like environment. When they correctly identify a scent, they are rewarded with treats from an automatic dispenser. Each dog has its unique way of signaling to its handler, showcasing the deep bond between humans and dogs.
