They’ve traveled all over the country, from the Sandy Hook shootings to the Boston Marathon bombings, as well as the scenes of many natural disasters. Now, 6-year-old Jo Jo the Comfort Dog is helping to ease the fears of young patients at a dental clinic in Illinois. The Golden Retriever, who was among the dogs who visited Sandy Hook in 2012, will lie in a child’s lap during dental procedures, helping relieve their stress by allowing them to hold her paw or pet her soft fur. Jo Jo’s handler, Lynne Ryan, is a dental assistant at Pediatric Dentistry of Northbrook, and it was her idea to have her dog visit the office once a month. “We take her wherever people need comfort," Ryan said. "It’s kind of like having a big stuffed animal in the office." — See photos at ABC News
