A 3-month-old German shepherd puppy with a congenitally dilated oesophagus had radiographic, cinefluoroscopic, and oesophageal motility studies before a modified Heller operation was performed. Subsequent examination of the oesophagus revealed no ganglion cells, and the condition was considered to be identical with human achalasia. In dogs, this appears to be more common in the German shepherd ...

Introduction Mitochondrial (mt) DNA analyses have suggested that dogs and wolves diverged in multiple events over 100 000 years ago, with a possible east Asian origin. The movement of humans and their dogs resulted in extensive gene flow between domestic dog populations for many thousands of years with further mtDNA analysis revealing that dogs display a high degree of polymorphism that is neit...
