It is well known that animals are sensitive to stress. And this is especially true for dogs. Researchers at Queen’s University Belfast, in Ireland, have discovered that these furry friends can actually smell stress in the sweat and breath of humans.

To reach this conclusion, the scientists conducted an experiment involving four dogs, named Treo, Fingal, Soot and Winnie, and about 40 people. They asked the human participants to try to solve a particularly difficult mathematics problem.
