Persistent Right Aortic Arch in dogs

Species: Dog
Condition: Persistent Right Aortic Arch
Organ System: Nervous/sensory

A vessel connection from the fetal period that fails to disappear after birth. Right aortic arch passes over the oesophagus, constricting it and affecting the proper food passage to the stomach. The problem is detected once the puppies start eating solid food. They regurgitate immediately after eating and subsequently fail to grow as fast as expected. They are thin, but have a big appetite. They have a visible bulge in the neck. Some puppies also have difficulties breathing if the trachea is also constricted. Surgical correction is recommended as soon as possible to avoid further stunted growth and other respiratory complications.
