Several studies have shown that therapy dogs help to reduce people’s pain levels and anxiety. Therapy dogs have also been found to increase patients’ physical, mental, emotional and social states and improve their quality of life.

Host Dr. Brian McDonough talks with David Frei, co-creator of Angel on a Leash, a charity supporting therapy dog programs that serve health care facilities, about how therapy dogs bring comfort, affection and happiness to people in confined living situations. Frei is the former host of The Westminster Kennel Club Dog Show and expert analyst for The National Dog Show on NBC Thanksgiving Day.
