In 2002, Roselle received an award from the American Kennel Club. It was in honor of “canine excellence” among service dogs. Two years later, a veterinarian diagnosed Roselle with immune-mediated thrombocytopenia, a disease that affects blood platelets. Hingson believes the toxic air conditions that she faced helping him escape on 9/11 caused her condition.
But the brave Roselle lived seven more years in the care of her loving family. Sadly, on June 26, 2011, Roselle passed away peacefully. Michael Hingson was right there by her side — just as she was always there for him.
