Hernias in Dogs: What You Need to Know

Hernias are not uncommon in dogs and can affect dogs of all breeds and ages. Understanding what hernias are, their causes, types, symptoms, and treatment options is essential for every dog owner. Here’s what you need to know about hernias in dogs.

What Is a Hernia?

A hernia occurs when an organ or tissue pushes through an opening or weak spot in the surrounding muscles or connective tissue. In dogs, hernias can develop in various areas of the body and may involve different types of tissues.

Types of Hernias in Dogs

  1. Inguinal Hernia: This type of hernia occurs in the groin area and is more common in females. It may involve the abdominal fat or intestines.
  2. Umbilical Hernia: An umbilical hernia is located near the belly button or navel. It is often seen in puppies and can involve abdominal fat or a loop of intestines.
  3. Diaphragmatic Hernia: Diaphragmatic hernias are rare but serious. They occur when part of the abdominal organs, such as the liver or intestines, pushes through the diaphragm into the chest cavity.
  4. Perineal Hernia: Perineal hernias occur near the pelvis and affect the rectal or anal area. They are more common in older, unneutered male dogs.

Causes of Hernias in Dogs

Hernias in dogs can have various causes, including:

  • Congenital: Some dogs are born with a predisposition to hernias, such as umbilical hernias.
  • Trauma: Blunt force trauma or injuries can weaken the abdominal muscles and lead to hernias.
  • Strain: Chronic straining during defecation or urination can contribute to perineal hernias.
  • Surgery: Previous abdominal surgeries can sometimes result in hernias.
  • Breeding Practices: Breeding dogs with a genetic predisposition to hernias can increase the likelihood of passing this trait to offspring.

Symptoms of Hernias in Dogs

The symptoms of a hernia can vary depending on the type and severity of the hernia. Common signs include:

  • A visible lump or swelling at the site of the hernia.
  • Pain or discomfort when touched.
  • Vomiting or diarrhea (if the hernia affects the intestines).
  • Difficulty breathing (in the case of diaphragmatic hernias).
  • Changes in behavior or appetite.
  • Straining during urination or defecation (in the case of perineal hernias).


If you suspect that your dog has a hernia, it’s essential to seek veterinary care promptly. Your veterinarian will perform a physical examination and may use diagnostic tools such as X-rays or ultrasound to confirm the presence and type of hernia.

Treatment Options

The treatment of a hernia in dogs depends on its type and severity:

  • Surgical Repair: Most hernias require surgical repair to prevent complications and relieve the dog’s discomfort. During surgery, the protruding tissue is placed back into its proper position, and the hernia opening is closed. Recovery after surgery usually involves restricted activity and pain management.
  • Monitoring: Small, asymptomatic hernias, such as some umbilical hernias in puppies, may not require immediate surgery. Your vet will monitor the hernia’s size and the dog’s overall health and may recommend surgery if necessary as the dog grows.
  • Diaphragmatic Hernias: Diaphragmatic hernias are considered emergencies due to their impact on breathing and organ function. Immediate surgical intervention is crucial in such cases.


While some hernias are congenital and cannot be prevented, responsible breeding practices can help reduce the risk of passing on hernia predispositions to offspring. Additionally, avoiding traumatic injuries and promptly addressing any signs of strain or discomfort in your dog can contribute to their overall health.

In conclusion, hernias in dogs are a relatively common medical issue that can vary in severity and location. Early diagnosis and appropriate treatment are essential to ensure your dog’s well-being and prevent complications. If you suspect your dog has a hernia or notice any concerning symptoms, consult your veterinarian for a thorough evaluation and guidance on the best course of action. Your dog’s health and comfort should always be a top priority.
