What illnesses can dogs detect?

Dogs can detect various illnesses by sniffing out specific volatile organic compounds (VOCs) associated with diseases, including cancer (breast, lung, prostate, skin), diabetes (blood sugar changes), Parkinson's disease, malaria, epileptic seizures, and even COVID-19, by detecting subtle scent changes in breath, urine, sweat, or skin samples. Their powerful sense of smell allows for early, non-invasive detection, potentially saving lives.
