Bengaluru-based Dognosis trains dogs to identify cancer-related odours in human breath samples, while AI analyses their responses.

A study involving more than 1,500 participants found sensitivity and specificity above 90 percent, supporting further evaluation in real-world screening programmes.

Patients breathe into a cotton mask for around 10 minutes before samples are taken to trained dogs for analysis.

Sensors monitor the animals’ breathing, brain activity and movements as they sniff.

Fifteen dogs are currently being trained, working for only 30 to 45 minutes daily. Researchers hope the approach could eventually provide an affordable first screening step before conventional medical testing.
