A hernia is a protrusion of an organ or tissue through an abnormal fissure or
opening that would normally close during development of your Westie. While there
are many types of hernias, two common sites for hernias are the groin and navel.
A hernia in the groin is called an inguinal hernia and one in the navel
is called an umbilical hernia.
If the bulge can be pushed back into the abdomen, the hernia is reducible. If
not, it is incarcerated. Any hard or painful swelling at the navel or in the
groin could be an incarcerated hernia and will require immediate veterinary
attention.
Umbilical hernias have a hereditary basis because there is a genetic
predisposition for delayed closure of the abdominal ring. Occasionally a navel
hernia may develop due to trauma: the umbilical cord is cut too close to the
abdominal wall or there is excess traction on an oversized fetus. Umbilical
hernias occur in puppies at approximately two weeks of age. Many times they get
smaller and can disappear by six months of age.
Inguinal hernias are more common in female dogs. A bulge in the groin may not
be seen until the bitch has been bred or becomes very old. These hernias should
be repaired.
Diagnosis is straightforward, especially if the hernia is manually reducible.
Correction is surgical and is often done at the same time as spay or neuter
procedures.
