Dogs really are man's best friends. A new study shows that dogs can smell if a person is feeling stressed(有压力的).

They can smell the difference in breath(呼吸) and sweat(汗液) from people. Then they can tell whether people are stressed or not. It could be 93. 75% right!
A study from scientists at Queen's University Belfast, the UK, said this. Scientists got breath and sweat from people both before and after doing a hard maths problem. They looked at the people's heart rate(心率), blood pressure(血压) and stress level(压力水平) in the study. The dogs found stress in 675 of the 720 people, or 93. 75% of the time, reported Australian news site *Kids News*.
“Stress changes people's breath and sweat. Dogs can smell that change,” said the study's writer Clara Wilson. In the study, she also said this finding helps us understand how dogs may know people's thoughts and feelings.
