Liquid barium esophagography was done in 29 clinically normal Chinese Shar Pei pups and observed fluoroscopically, beginning when they were approximately 3 months old and repeated periodically until they were at least 18 months old, if possible. Of these dogs, 69% had relatively slow stimulation of secondary waves, 48% had generalized poor esophageal tone or motility, and 38% had esophageal redundancy. Sequential studies revealed apparent improvement with age for these dogs initially showing slow motility, provided that redundancy was not also present. Another group of 9 Chinese Shar Pei pups had histories of either regurgitation or vomiting. Five of these had hiatal hernia and 2 had megaesophagus.
