Some dogs have yet to learn to sniff out the so-called tissue organic compounds (VOCs) that make up the scent profile of a hunter, according to a study published in the scientific journal Frontiers in Allergy. Some of the organic tissue of the skin is related to stress, which was found in a test with a golden retriever named Ivy and a German shepherd named Callie.

Post-traumatic stress disorder is a mental illness caused by frightening or stressful events, which sufferers often experience in nightmares and memories.

During the study, there were 26 people, of whom less than half met the diagnostic requirements for post-traumatic stress disorder, for example, that they breathed into the layers of masks and recalled traumatic events from the past.

According to the researchers, out of 25 trained dogs, only Ivy and Callie were able to distinguish the samples from the face masks of stressed people from samples of non-stressed people with 90 percent accuracy.

For both Ivy and Callie, the work was intrinsically motivating, said Laura Kiirojaov of the Department of Psychology and Neuroscience at Canada’s Dalhousie University. Their unlimited appetite for delicious treats was a good fit. In fact, it was much more difficult to convince them to get a crop, not to start working. Callie, in particular, made sure it didn’t go down to the bottom, she added.

Previous research has shown that dogs can detect diseases such as cancer, as well as early signs of potentially dangerous health conditions, such as panic attacks or sudden hypoglycemia, when blood sugar levels drop abnormally.

There are dogs that have been trained to help people during crisis episodes, but only respond to behavioral or physical signals. Kiirojaov said the results of this study could make assistance dog therapy more effective for people with PTSD.
