Therapy Dogs Help Patients In Hospital Intensive Care Unit Carol Pearson WASHINGTON - Studies show when people pet an animal, their blood pressure goes down along with stress and anxiety. That's why there are so many therapy dogs in schools, counseling centers and even in hospitals. Taz wags his tail when he greets patients at the University of Missouri Hospital. Taz and Bruce Miller are part of a therapy dog team. "He gets a lot of attention -- haha -- and he loves the attention," Miller said. Taz is trained to provide comfort and emotional support to the patients he visits. And while no one wants to be in a hospital, Kevin Gwin's job is to make sure a stay at the University of Missouri Hospital is a positive one. "I think sometimes patients feel isolated," Gwin said. "They get out here, it's lonely, it's boring. And the dogs are something to look forward to, and when they visit, the whole unit comes alive."
