Idrees Mohammed, AFP&nbsp;</div>When rescue dog Chloe is not tumbling across the grass on a farm outside India&#39;s tech capital Bengaluru, she is learning to sniff human breath for cancer with a little help from AI.Fitted with a 3D-printed helmet and harness packed with sensors, Chloe is part of experimental efforts to use dogs&#39; extraordinary sense of smell to develop a non-invasive test for the disease.A growing body of global research suggests dogs can be trained to detect cancer and other human illnesses, from Parkinson&#39;s to Covid-19.The&nbsp;Bengaluru-based startup Dognosis is using AI to analyze dogs&#39; brain activity, respiration and body language -- turning their reaction to scent into data.&quot;In an hour, they can do thousands of sniffs,&quot; co-founder Akash Kulgod, 26, told AFP. &quot;Each sniff can evaluate a sample.&quot;Dognosis hopes to launch commercially next year, which it says would make it the third company of its kind, after firms from Germany and Israel.Early detection can make a crucial difference to cancer survival rates, but in India many patients are diagnosed only after the disease has advanced.Dog sniffs could provide an easy and affordable first layer of screening to be deployed at scale, finding potential cases for further testing.As it chases commercial approval, Dognosis -- backed by venture-capital firms including Accel India -- is collaborating with government medical institutions for its research.Chloe, a Labrador mix, is one of 15 dogs being coached by the startup, clad in customized data-gathering helmets.&quot;It&#39;s like a doggy &#39;Iron Man&#39; suit,&quot; said Kulgod, who comes from a family of doctors and studied cognitive science at the University of California, Berkeley.<div> </div><div>&#39;PROMISING&#39; STUDY</div><div> </div>Research suggests diseases can alter the chemicals released by the body, creating distinctive odors.Dogs have around 300 million scent receptors, compared to about five million in humans.The testing method is simple: a patient breathes into a cotton mask for about 10 minutes, and the mask is then sealed in a bag and taken to the lab. Patients do not meet the dogs.A recent Dognosis study of more than 1,500 participants, involving six hospitals in Karnataka state, was published in the Journal of Clinical Oncology.The company said it achieved an accuracy rate of more than 90 percent across seven major types of cancer, and now plans to test in real-world programs.&nbsp;Cancer specialists in Bengaluru independent of the project voiced cautious optimism.&quot;The study is promising, as an early signal,&quot; said Santhosh Kumar Devadas, head of oncology at Ramaiah Memorial Hospital.&quot;But they need to do the study with a much larger group before we make any definitive conclusions.&quot;Neelesh Reddy, a senior consultant oncologist at Manipal Hospitals, told AFP that &quot;only time will tell how this technology will be useful to the actual patients&quot;.<div> </div><div>DOG &#39;WORK-LIFE&#39; BALANCE&nbsp;</div><div> </div>India has described cancer as a major public health concern, saying one in nine of its 1.4 billion people are likely to develop the disease.Dognosis says it aims to improve &quot;proactive and preventative medicine&quot; while boosting &quot;human-canine communication&quot;.Most of the dogs are beagles, along with some Malinois and Shepherd mixes, brought on board through adoption or legal breeders.But only the best are selected, said Kulgod. The dog team individually lists each animal on the company website as an official &quot;sniffer&quot;, alongside their photographs.All have a great &quot;work-life balance&quot;, with work time limited to around 30-45 minutes a day, he added.At a center called &quot;Sniffspace&quot;, dogs test human samples on platforms equipped with automatic feeders dispensing dog treats.Kulgod&#39;s co-founder Itamar Bitan, 28, who spent four years in an Israeli special-forces canine unit, said the dogs were trained using &quot;positive reinforcement&quot; to detect a &quot;specific funky smell&quot; for a reward.&quot;Some of the dogs run directly to the feeder expecting rewards, some dogs freeze, some dogs will scratch the sample with excitement,&quot; Bitan said.&quot;But, as long as the machine that learns how the dogs react to the sample is very consistent... we don&#39;t really mind.&quot;

A growing body of global research suggests dogs can be trained to detect cancer and other human illnesses, from Parkinson's to Covid-19.
