Studies have found that pets can help boost health in a host of ways. They can give you more opportunities to be active. And they may help keep your stress low and your blood pressure in a healthy range. On the other hand, when a pet becomes sick, stress can rise. So, try to make routine visits to the vet. With routine care, many pet diseases can be prevented, and others can be treated if caught early. That may mean a healthier life for both of you.
