Dogs Mirror Their Owner's Stress Levels, Finds a Study

To all the dog lovers out there - you called it! Your dog does mimic your stress levels.

A Swedish study found dogs mirror their owner’s stress levels.

Researchers at Linköping University conducted the study by measuring the concentration of stress hormone, cortisol, in hair from dogs and their owners. They found long-term levels of cortisol in dogs and their owners were synchronized. The study included 25 border collies and 22 Shetland sheepdogs - both herding dog breeds. All of them were owned by women. The Swedish researchers hope to expand their study into other breeds.
