CHARLESTON, S.C. (WCIV) -- Young Mary Ashley Barbot has been on a mission to save her own life and raise awareness for transplant patients. Now some friends are chipping in with some dog races.She was born with congenital nephrodic syndrome, meaning her kidneys did not work as they should at birth. She underwent a life-saving kidney transplant when she was two years old, but now her body is rejecting that kidney as well. When ABC News 4 introduced her to Charleston to 10-year-old in July, dozens of people responded, willing to be tested as a possible living donor. Unfortunately, doctors have yet to find a match for Mary Ashley. But there is another way the public can help. On Saturday, friends of the Barbots are holding a special fundraiser at Joe Riley Park.The "Who Let The Dogs Out" fundraiser features plenty of little dachshunds racing. It's being held to raise awareness about organ donation and to collect money for a potential living donor. The races begin at 9 a.m. and there will even be a costume contest.
