According to a study conducted at the Linköping University, Sweden dogs mirror their owners stress level. The study is just the beginning and more research is needed. The dogs in the study were Border Collies and Shetland Sheepdogs owned by woman. The researchers did note that the higher level of stress did not influence the dog’s personality but it did affect the owners. They also took into consideration that the two breeds studied are bred to respond quickly to commands from their owners. Additional studies are planned to

explore other breeds with the goal of being able to match dogs and people more successfully. They want to see if other breeds are not as affected by their owner’s stress level.
Sue’s Note: It is critical that the climate of a household and the people in it are seriously considered when selecting a breed or type of dog to add to the family. Certain breeds are more active than others. It is never a good idea to introduce a highly excitable dog into a very active household. For example, some terriers may not be a good match for a home where there are young, highly active children. Just like people, dogs can reach their tolerance level and if pushed too far may withdraw or bite.
