Hernias in Dogs – Definition
A hernia is defined as any abnormal protrusion of part of an organ or tissue through the structures that normally contain or surround it. In most cases, affected animals have a weak spot, an unusual opening or some other abnormality in a body wall that permits part of another organ to bulge through it, although sometimes the herniation protrudes through a natural opening in the body wall. The tissues that tend to protrude through the body wall are often fat and/or bowels (intestines). A common layman’s term for a hernia is a “rupture.”
The most common sites of hernias in domestic dogs are located in various parts of the abdominal cavity. A hernia in the groin area is called an inguinal hernia, and a hernia in the navel (belly button) area is called an umbilical hernia. These two common types of canine hernias are most commonly seen in puppies as a result of some developmental defect. Hernias near the area of the anus and rectum are referred to as perineal hernias and usually occur in older dogs. Another common site of hernias in dogs is the diaphragm, which is the muscular partition that separates the thoracic (chest) and abdominal cavities. Diaphragmatic hernias involve protrusion of some abdominal organs or tissues through an abnormal hole or defect in the diaphragm and typically are referred to as hiatal hernias.
Hernias in dogs can be either congenital or acquired. Congenital hernias are those that are present at birth; they may or may not have a hereditary component. Congenital hernias involve the failure of some part of an internal or external body wall to close normally during neonatal development and typically involve defects in the diaphragm or other parts of the abdominal wall. Acquired hernias are those that develop sometime after the dog is born. Acquired
Hernias can cause a number of different symptoms and clinical signs in an individual dog. However, most of the time, the dog does not seem to be very affected by the hernia and does not show any or many signs of distress or discomfort. In some cases, especially with diaphragmatic hernias, affected dogs will suffer respiratory difficulties and/or abdominal pain.Many dogs with hernias will show no observable signs of distress, discomfort or illness. This is
Most hernias are best definitively diagnosed by radiographs (X-rays), which will reveal the abnormal position of the tissue or organs that are protruding through the herniation defect. More specific radiographic contrast studies are often recommended to confirm the diagnosis. Contrast studies involve introducing special contrast media, such as barium, into the dog’s system either orally or by injection. As the contrast medium moves through the dog’s digestive tract, it will accentuate any hernia defects on
Surgical correction after consultation with a qualified veterinary professional is the standard of care for treating hernias in dogs. The earlier that a hernia can be repaired is usually the better. Prompt surgical correction can help to prevent the formation of tissue adhesions and entrapment of organs within the site of the herniation.If the protruding tissue of a hernia can be manually pushed back through the defect in the body wall (which usually but not
