Dognosis pairs trained sniffer dogs with artificial intelligence to flag cancer from a breath sample. It is a charming idea aimed at a real problem, with equally real caveats: this is prescreening in trials, not a proven diagnostic.
A dog’s nose has long outclassed most laboratory kit, and a two-year-old Bengaluru startup called Dognosis is betting it can turn that biological talent into a screening tool.
The company pairs trained sniffer dogs with sensors and artificial intelligence to flag early signs of cancer from a single breath sample, the latest entry in a busy field where AI is being pointed at cancer detection.
The process is disarmingly simple at the patient’s end. You breathe into a mask, which is then couriered to Dognosis’s facility, a farm outside Bengaluru, where beagles, labradors and Dutch shepherds sniff the sample.
As they do, sensors and AI read the animals’ movements, respiration, brain activity and body language, translating a pause or a wag into structured data. The premise is that tumours leave a chemical signature in exhaled breath, one a dog can smell long before conventional tools can see it.
