Your Puppy Has an Umbilical Hernia: What It Means and What to Do

Discovering a small lump near your puppy’s belly button can understandably cause a wave of concern, but in many cases, an umbilical hernia is a common and very manageable condition. Understanding what you’re dealing with — and knowing when to act — can make all the difference for your growing pup. This guide walks you through everything you need to know, from causes and symptoms to treatment options and when to call your vet.

Common Causes

An umbilical hernia occurs when a small opening in the abdominal wall near the belly button doesn’t close properly after birth. In healthy puppies, this opening seals on its own shortly after the umbilical cord is cut. When it doesn’t fully close, a portion of fat or, in more serious cases, abdominal tissue can push through, creating a soft lump you can feel or see.

While it may sound alarming, umbilical hernias are among the most frequently seen congenital conditions in puppies, and they’re often detected during a routine wellness exam. Several factors can contribute to their development:

• Genetics: Many umbilical hernias are hereditary, meaning certain breeds are predisposed. Breeds such as Airedale Terriers, Basenjis, Pekingese, and mixed breeds are known to carry a higher genetic risk.
• Improper cord clamping: If the umbilical cord was cut or clamped too close to the abdominal wall during birth, it can interfere with normal healing and closure.
• Natural variation in healing: Some puppies simply take longer for the umbilical ring to close, and in certain cases, it never fully seals on its own.
• Difficult birthing process: Excessive straining during whelping can put pressure on the abdominal wall, increasing the likelihood of a hernia forming.
• Infection or trauma: Though less common, infection near the navel or early physical trauma to the area can also contribute to the development of a hernia.

From a clinical standpoint, diagnosing the type and severity of an umbilical hernia is usually straightforward. Your veterinarian will palpate — gently feel — the lump during a physical exam to determine whether it is reducible (easily pushed back through the opening) or non-reducible (firm and fixed in place). In most cases, no imaging is needed for small, uncomplicated hernias. However, if your vet suspects intestinal involvement or cannot confidently classify the hernia by feel alone, they may recommend an ultrasound to get a clearer picture of what’s inside that little bulge.

Age plays an important role here. The umbilical ring is typically expected to close within the first few weeks of life. Most veterinarians consider a hernia unlikely to self-resolve if it persists beyond three to four months of age, which is why early evaluation matters. Puppies are commonly first assessed for umbilical hernias at their initial wellness visits — usually around six to eight weeks old — making those early vet appointments genuinely valuable beyond just vaccinations.

It’s also worth noting that the size of the hernia opening, called the hernial ring, is what largely determines risk — not just the visible size of the lump itself. A small-looking bulge can occasionally have a larger-than-expected opening beneath the skin, which is another reason a hands-on veterinary assessment is so important. Small, soft hernias that can be gently pushed back in with light pressure are called reducible hernias and are generally considered lower risk. Larger or firm hernias that cannot be pushed back are non-reducible and require prompt veterinary attention.

Symptoms to Watch For

In many puppies, an umbilical hernia is discovered by a veterinarian during a routine exam before the owner even notices anything unusual. That said, there are clear signs you can watch for at home:

• A soft, round lump near the navel: This is the most obvious sign. It may be small — about the size of a pea — or larger, depending on the severity of the hernia.
• A lump that fluctuates in size: You may notice the bulge appears larger when your puppy is active, crying, or straining, and smaller when they are calm and relaxed.
• Redness, warmth, or swelling around the area: These signs can indicate inflammation or, in serious cases, tissue becoming trapped, which is a medical emergency.
• Pain or sensitivity when the area is touched: A puppy that flinches, whimpers, or pulls away when you gently touch the lump may be experiencing discomfort.
• Vomiting, lethargy, or loss of appetite: These systemic symptoms can signal that intestinal tissue is trapped in the hernia, a dangerous situation that requires immediate veterinary care.

If your puppy’s hernia lump suddenly becomes hard, discolored, or is accompanied by any of those last symptoms, don’t wait — contact your veterinarian right away.

Breeds Most at Risk

While any puppy can develop an umbilical hernia, certain breeds have a well-documented genetic predisposition that makes them more likely to be born with or develop this condition.

Airedale Terriers are one of the most frequently cited breeds in veterinary literature when it comes to congenital umbilical hernias. The condition appears to run strongly in family lines within this breed, suggesting a clear hereditary component. If you have an Airedale puppy, a thorough abdominal check at every early wellness visit is especially worthwhile.

Basenjis are another breed with a recognized higher incidence of umbilical hernias. Like Airedales, the predisposition in Basenjis is believed to be genetic, and responsible breeders working with this breed are often aware of the trait and screen for it in breeding pairs. If you’re adopting a Basenji puppy, asking the breeder about the parents’ health history is a reasonable and informative question.

Pekingese also show up with notable frequency in umbilical hernia cases. Their compact body conformation and specific genetic makeup appear to contribute to a higher rate of incomplete umbilical ring closure. Because Pekingese puppies can also be prone to other structural health concerns, early and consistent veterinary monitoring is especially important for this breed.

It’s worth noting that mixed-breed dogs are not immune — in fact, because hereditary hernias can be passed along from any predisposed parent breed, mixed breeds can and do develop umbilical hernias. Knowing your puppy’s parentage, when possible, adds useful context for your vet.

What You Can Do at Home

When you first notice a lump near your puppy’s belly button, the most important thing you can do is stay calm and assess the situation carefully. Gently feel the lump with clean hands. If it is soft, moves easily, and your puppy doesn’t react with discomfort, it is likely a reducible hernia that isn’t causing immediate distress.

At home, your role is primarily one of monitoring rather than treating. There is no safe or effective home remedy for closing an umbilical hernia, and attempting to manipulate or bandage the area yourself can cause harm. Instead, focus on the following:

• Keep the area clean and dry. Avoid letting the lump become irritated by rough surfaces, excessive licking, or trauma.
• Monitor the lump regularly. Check it daily for any changes in size, texture, color, or your puppy’s reaction to touch.
• Keep a written log of what you observe. Noting any changes over time will be genuinely helpful information to share with your veterinarian.
• Avoid rough play that puts pressure on your puppy’s abdomen until you’ve had the hernia evaluated by a professional.

Some very small umbilical hernias do close on their own by the time a puppy reaches three to four months of age. However, this is something your veterinarian should assess and monitor — not something to wait out indefinitely without professional guidance.

When to See a Vet

Every puppy with a suspected umbilical hernia should be seen by a veterinarian, even if the lump appears small and your pup seems perfectly happy. A vet can properly classify the hernia, determine whether it poses any immediate risk, and recommend the appropriate course of action.

Surgical correction is the standard treatment for umbilical hernias that don’t resolve on their own. The procedure is straightforward and is frequently performed at the same time as a spay or neuter surgery, which helps minimize anesthesia exposure and recovery time. Your vet will advise you on the best timing based on your puppy’s age, size, and overall health.

Seek emergency veterinary care immediately if you notice:

• The lump has become hard, dark, or discolored
• Your puppy is vomiting repeatedly or refusing all food
• Your puppy appears lethargic, weak, or in obvious pain
• The hernia has increased significantly in size over a short period

These signs can indicate a strangulated hernia, in which blood supply to trapped tissue is cut off. This is a life-threatening emergency that requires surgery without delay.
