The NTUAS Study Group is a multi-disciplinary collaboration, led by Dr. Bryden J. Stanley, formed to clearly characterize the condition by performing in-depth evaluations on many Norwich terriers of all ages. The study was funded by donor-advised funds from the Norwich Terrier Club of America, through the Canine Health Foundation (CHF Grant 2232-MOU), and by the generous donations of Norwich Terrier owners and friends.
