Dog owners show better responses to stress（their blood pressure and pulse rates don't soar）,have higher levels of physical activity and slightly lowercholesterollevels.

Of course,getting a dog and watching it from your sofa while you eat fatty food is not going to reduce your risk of heart disease.And a toy dog may look cute,but won't have any effect either.Fall's study showed the most health benefits came from having retrievers or pointers（指示犬）.Until her German short-haired pointer died last year,she ran 10 km with her most days. “In Sweden,we have one of the lowest rates of dog ownership in Europe,”says Fall,who has recently got a new puppy.“Maybe this will increase the acceptance that dogs are important to people.”test with proper meanings.
