Clinical Corner Answer - October
The answer is Hiatal Hernia. A hernia is most likely to occur in puppies less than a year old and is usually inherited (congenital). It can occur in any breed, gender or age, but there does appear to be a predispotition for male animals, and with Chinese Shar-Pei and English bulldogs more than other breeds.
It occurs when one part of the body protrudes through a gap or opening into another part. A hiatal hernia, specifically, is when the lower oesophageal sphincter slides into the thoracic cavity and allows gastric reflux into the oesophagus, causing inflammation of the oesophagus.
