The relationship a dog has with its owner is related to its stress level. This is the conclusion of a newly published study from Linköping University, Sweden. The results, published in the journal
Scientific Reports, also suggest that the link between stress and the owner s personality traits differs between dog breeds.
Researchers at Linköping University have investigated whether the stress levels of dogs are affected by the people they live with. Stress levels for the past several months can be determined in both dogs and humans by measuring the levels of stress hormone stored in hairs as they grow.

Can long-term stress lead to heart attacks? Most people would probably answer in the affirmative, but the scientific evidence of this is scarce. A new study by researchers from Linköping University in Sweden reveals that the levels of the stress hormone cortisol were increased in the months preceding a heart attack. The results, published in
Scientific Reports, suggest that long-term stress is a risk factor for heart attacks. The levels of the stress hormone cortisol differed between people who have had a heart attack and those not affected. This suggests that cortisol in hair may be a new risk marker for heart attacks. We must take stress seriously , says Professor Tomas Faresjö from the Department of Health, Medicine and Caring Sciences at Linköping University, principal investigator of the study.
