And 650 out of 700 times, the dogs successfully selected the canister that contained a breath or sweat sample from a depressed person. The dog is man's best friend and loyal pet, this has been proven true once again. This time, a scientifically based experiment on dogs' sense of smell has shown how finely this pet can understand our feelings. Scientists discovered in this experiment that dogs can smell stress in the scent of our breath and sweat In this experiment, four pet dogs were trained to 'choose' one of three scent canisters by sniffing them. The owners of these dogs volunteered for the experiment. And 650 out of 700 times, the dogs successfully selected the canister that contained a breath or sweat sample from a depressed person.
Researchers from Queen's University Belfast hope their research, published in the journal Plus One, will help train therapy dogsA dog's nose is very sensitive to any scent or smellDogs experience their world through smell. And their highly sensitive olfactory abilities are already used to detect drugs, explosives, and diseases. Which some cancers, diabetes,s and even covid disease have been detected. Lead researcher Clara Wilson said: 'We have a lot of evidence that dogs can smell smells from humans linked to certain medical conditions or disease. But we don't have much evidence that they can even smell changes in our psychological or mental state.''A pet dog named Suit is involved in this experiment For further research and evidence, 36 volunteers were asked to solve a difficult math question, after which they reported stress before and after solving the question.
Each of them saved a sample of their breath or sweat before and after their stressful state, or while their blood pressure was elevated or their heart rate was elevated. And while these pet dogs, Trev, Fungal, Sut, and Winnie, stood or sat in front of the 'mental stress' sample during the experiment, they were given food of their choice.
