Umbilical Hernias in Dogs: Symptoms, Causes and Detailed Treatments

We all love rubbing puppies' soft, pink bellies, and that's because It's impossible not to tickle and cuddle them. when they are so small. However, during these caresses, many people may notice that on this soft skin there is a strange bump, which is technically known as umbilical hernia.

What is umbilical hernia in dogs?

Detecting a lump in a puppy can be quite stressful for owners, as no one wants their pet to have health problems at such a young age. To understand this, we need to know that a hernia it is basically a muscle weakness or a defect in the abdominal wall. When a muscle is very weak or has an opening, the internal contents of the abdomen (such as fat or intestinal tissue) shift outwards, resulting in a small bump under the skin or even the feeling of a void.

From an anatomical point of view, the hernia is composed of a ring (the edge of the muscle defect) and, occasionally, a peritoneal sac that covers the protruding organs. There are fundamentally two types of hernias according to their progression:

• Uncomplicated hernias: These are those that generally disappear in the first few months of life of the puppy. They have a very small diameter and usually close on their own without the need for surgical intervention.
• Complicated hernias: These represent a real health risk in dogs. They occur when muscle weakness is severe, the lump protrudes excessively, or a significant gap opens in the abdomen. If left untreated, can cause serious consequences such as strangulation of organs, almost always requiring surgery.

What are umbilical hernias in dogs and how do they form?

Umbilical hernias or navel hernias They are the most common in caninesIt is frequently detected in puppies under 6 months old. To understand its origin, we must remember that at birth, just as with humans, dogs have their umbilical cord cutThis cord is the feeding route during gestation; once cut, the tissue must heal and the abdominal cavity must close completely around it.

When the umbilical ring does not close properly Due to a defect in embryogenesis, an opening remains connecting the subcutaneous area to the abdominal cavity. A fetus can pass through this opening. fatty tissue or intestinal loopsTherefore, the name "umbilical" refers directly to the location of the hernia: right where the human navel.

What Causes an Umbilical Hernia?

Although the immediate cause may be weakness in the abdominal musclesThe root of the problem is usually the Genetic heritageThere are breeds with a marked predisposition to this defect, such as the Pekingese, Basenji or Aire DaleBecause of this, some breeders avoid reproducing genetic lines with this tendency.

In addition to congenital causes, it is important to mention that in adult dogs abdominal hernias can arise for other reasons:

• Trauma: Traffic accidents, severe blows or penetrating bites.
• Pregnancies: Abdominal pressure during pregnancy can weaken the abdominal wall.
• Obesity: Excess weight creates constant intra-abdominal pressure that can expand an already weakened ring.

How are umbilical hernias and other types of hernias detected?

Umbilical hernias they are very easy to notice Visually, they appear as bumps on the abdomen. Because the fur is usually sparser and the skin is thinner in that area, they are easy to detect. It is generally a soft, uniform lump which may disappear when gently pressed or when the dog lies on its back.

However, it is vital to know that there are other types of hernias that require different monitoring:

• Herniated Disc: It affects the intervertebral discs of the spine, compressing the spinal cord. It causes lower back pain, paralysis or difficulty walking.
• Inguinal Hernia: It appears in the groin, where the abdomen joins the hind legs. It can trap intestines and cause vomiting or severe pain.
• Perineal Hernia: Common in uncastrated males, it is located near the anus and causes constipation or difficulty defecating.
• Diaphragmatic Hernia: It is the most serious. Abdominal organs pass into the chest, causing severe respiratory distress and fatigue.

Diagnosis and treatment of umbilical hernias

Umbilical hernias They tend to be the easiest to solveIn most uncomplicated cases, the ring closes spontaneously as the puppy grows, usually before 6 months of age.

If the hernia persists, the veterinarian will assess its severity. A key point is whether the puppy has less than eight weeksIt is usually recommended to wait, as the opening may change. In some mild cases, it may be possible to try to push the contents inwards and temporarily fix the area with a button and dressing.

When the dog is more mature, or reaches an approximate weight of two and a half kilosThe veterinarian may recommend a hernia surgeryThis intervention is simple and often takes advantage of the moment of spaying or neutering to perform it under the same anesthesia.

The surgical process and its objectives

The surgery aims ensure the viability of the organs trapped and restored to their correct anatomical position. The procedure consists of:

1. Make an elliptical cut in the skin surrounding the hernial sac.
2. Clear the inner sac until you reach the muscular opening.
3. Press the contents into the abdominal cavity (or remove necrotic tissue if strangulation occurred).
4. Close the abdominal wall using sutures, sometimes using abdominal reinforcement mesh in cases of severe weakness to prevent relapses.

When is a medical emergency?

It is essential to attend Take him to the vet urgently If the lump becomes hard, changes color (turns purplish or red), or if the dog shows:

• Vomiting and loss of appetite.
• Diarrhea or constipation prolonged.
• Intense pain upon touching the protuberance.

These are signs of intestinal strangulationwhere blood flow is cut off, causing tissue death and potentially fatal peritonitis.

Recovery and postoperative care

The postoperative period is usually quick and straightforward, but it requires discipline. To ensure success, the following is recommended:

• Absolute rest: Avoid jumping, running, or climbing stairs so that the stitches do not come undone.
• Wound hygiene: Clean the area if it gets dirty and prevent the dog from licking the scar (using Elizabethan collars if necessary).
• Feeding: Provide high-quality food to promote tissue regeneration.
• Weight control: Keep the dog at its ideal weight to avoid putting extra pressure on the repaired area.

The overall prognosis is very good, and recurrences are rare if the appropriate surgical technique is used. Early detection and professional follow-up are the best ways to ensure our four-legged companion grows up healthy and happy.
