Dog in training to detect COVID in human sweat samples.
The cone allows the dog to sniff the scent of samples placed inside glass containers, while the white sheet serves as a control when the dog has not detected any sample positive for COVID. This simple and ingenious research method serves to strengthen the reliability of the test results.
Research is promising and ongoing where dogs are being trained to detect various pathologies, such as cancer and diabetes.
Did you know that dogs possess a sense of smell many times more sensitive than even the most advanced man-made instrument and the part of a dog's brain devoted to analysing smells is about 40 times greater than ours? Try wiggling your nostrils on that canine fact!
