Yes, dogs have belly buttons. A dog belly button is a small, flat scar left behind after the umbilical cord detaches at birth, and it sits on the midline of the abdomen just below the ribcage. Unlike a human navel, it doesn't pop in or out, so fur and its faint shape make it easy to miss entirely.
If you have ever given your dog a belly rub and wondered whether that soft, furry tummy hides a navel like yours, you are not alone. It is one of the most common curiosities dog owners have, and the answer opens a small window into how puppies grow before they are born. Below, we cover exactly where the belly button is, why it is so hard to spot, what a healthy one looks like, and the one situation, an umbilical hernia, where that spot is worth a closer look.
Do Dogs Really Have Belly Buttons?
They do. Nearly every mammal, including dogs, cats, and humans, has a belly button, because we are all placental mammals nourished by an umbilical cord in the womb. As the Hill's Pet team explains, "almost all mammals have a belly button," the notable exceptions being egg-laying animals like birds and reptiles.
Before a puppy is born, the umbilical cord runs from the mother's placenta to the developing pup, carrying oxygen and nutrients in and waste out. After birth, the mother dog typically chews through the cord, which then dries up and falls off within a few days. What remains is a permanent scar, the belly button, technically called the umbilicus. According to the American Kennel Club, dogs "do have belly buttons" even though "they might be covered in fur and almost impossible to find." If you want to see this whole process in context, our guide to the five stages of newborn puppies walks through those first fragile weeks day by day.
Where Is a Dog's Belly Button Located?
Your dog's belly button is on the underside of the body, along the center line of the abdomen, just below the ribcage. This is higher up the belly than many people expect. On a human, the navel sits low on the stomach, but on a dog it is closer to the base of the rib cage, often roughly between the first pair or two of nipples.
To find it, wait for a moment when your dog is relaxed and lying belly-up, then gently part the fur along the midline below the ribs. PetMD notes that the belly button appears as a "small, flat scar" that is "not as pronounced as the ones humans have." You may feel a tiny vertical slit or a slight pucker in the skin more than you can see it. If your dog is not a fan of having their tummy handled, do not force it, plenty of dogs live long, happy lives without their owners ever locating the exact spot. Speaking of belly-up poses, if your pup loves sleeping on their back, our breakdown of what your dog's sleeping positions mean explains why that vulnerable posture is usually a great sign.
Why Is a Dog's Belly Button So Hard to See?
Three things conspire to hide a dog's navel. First, fur. Even short-coated breeds have enough hair over the abdomen to obscure a small, flat scar, and fluffy or double-coated dogs make it nearly invisible. Some dogs even have a small whorl or swirl of fur over the spot.
Second, size. A puppy's umbilical cord is far thinner than a human baby's, so the scar it leaves is tiny to begin with. Third, shape. A human navel is dramatic because our cord was cut and clamped, leaving a knot of tissue that heals into an "innie" or an "outie." A dog's cord is chewed close to the body and the wound heals almost perfectly flat. As Dogster's vet-reviewed guide puts it, dogs have "one small vertical slit or a slightly oval-shaped scar tissue, but unless you're specifically looking for it, it's pretty easy to miss." The result is a mark so subtle that many devoted owners have never once noticed it.
What Does a Normal Dog Belly Button Look Like?
A healthy dog belly button is flat, faint, and unremarkable. Look for a thin vertical line, a small oval of slightly different skin, or a faint pucker or dimple along the midline. The skin over it should look the same color and texture as the surrounding belly, with no swelling, no lump, no redness, and no discharge. It should not be tender, and touching it should not bother your dog.
Because it is just scar tissue, a normal navel needs no special care, cleaning, or attention. It serves no function in an adult dog, it is simply a leftover reminder of life in the womb. If the belly skin around it looks flaky or irritated in general, that is usually a coat or skin issue rather than a navel problem, and our tips on safe home remedies for dry skin in dogs can help you tell the difference. The one thing that should change your assessment is a bulge, which brings us to umbilical hernias.
Umbilical Hernias: When a "Belly Button" Bulge Needs a Vet
This section is general information, not veterinary advice. Only your veterinarian can examine your dog and tell you what a bulge actually is.
Sometimes the small opening in the abdominal wall where the umbilical cord passed through does not close completely after birth. When that happens, a bit of fat or tissue can push through, creating a soft, protruding bump right at the belly button, essentially a canine "outie." This is called an umbilical hernia, and according to VCA Animal Hospitals, it is among the most common hernias seen in young puppies.
Many small umbilical hernias are minor. Chewy's vet-reviewed overview notes that small hernias "may close on their own until a puppy is 3 to 4 months of age," and when repair is needed, vets often schedule it alongside a routine spay or neuter. VCA similarly reassures owners that umbilical hernias "are not painful and aren't typically emergencies, so surgery can wait until the time of the spay or neuter" in many cases.
That said, this is a health topic where guessing is a bad idea. Call or see your veterinarian if you notice any of the following at or near your dog's navel: a soft or firm bulge that was not there before, swelling, redness, warmth, or discharge, a bump that seems to grow, or any sign that your dog is in pain, is vomiting, or seems unwell. A hernia that traps tissue and cuts off its blood supply is rare but is a genuine emergency. When in doubt, let a professional feel the spot, do not press hard on it, try to push it back in yourself, or attempt any home treatment. A quick exam is exactly the kind of thing vets check at early visits, which we cover in our guides to bringing home a new puppy and basic puppy first aid.
Do Other Animals Have Belly Buttons?
Yes, and knowing which animals do makes the whole thing click. Belly buttons are a placental-mammal feature, so cats, horses, cows, whales, elephants, and of course humans all have some form of navel, usually a faint, flat scar rather than the pronounced knot we humans carry. Cats have belly buttons in the same midline spot as dogs, and they are just as hard to find under the fur.
Animals that hatch from eggs, like birds, reptiles, and fish, do not have belly buttons, because there is no umbilical cord connecting them to a placenta. Marsupials such as kangaroos are a quirky middle case, with only a very brief internal cord. The ASPCA's general dog care resources are a good reminder that these small anatomical details sit alongside the everyday basics, nutrition, exercise, and routine checkups, that actually keep your dog thriving. The belly button itself is mostly a fun piece of trivia.
Frequently Asked Questions About Dog Belly Buttons
Can I actually feel my dog's belly button?
Often, yes. During a relaxed belly rub, part the fur along the midline just below the ribcage and feel for a tiny vertical slit or a faint pucker in the skin. Many owners feel it more easily than they see it, and some never locate it at all, which is completely normal.
Why doesn't my dog have an "innie" or "outie" like me?
Because a puppy's umbilical cord is thin and is chewed close to the body rather than cut and clamped, the wound heals almost perfectly flat. That is why a dog's navel is a faint scar instead of the raised or recessed shape people have.
Is a bump on my dog's belly button dangerous?
A soft bump could be an umbilical hernia, which is common in puppies and often minor, but a bump can also be other things. Because you cannot diagnose it by looking, have your veterinarian examine any new swelling, firmness, redness, discharge, or a bulge that grows or seems painful.
Do belly buttons ever cause dogs problems as adults?
A normal, fully healed navel causes no problems at all, it is just scar tissue with no function. The main belly-button-related issue is an umbilical hernia, and those are usually identified when a dog is young, often repaired during spay or neuter surgery if needed.
Do all dog breeds have belly buttons?
Yes. Every dog of every breed is born with an umbilical cord and therefore has a belly button. Coat type just changes how visible it is, thick or fluffy coats hide the scar more thoroughly than short, sparse ones.
Should I clean or put anything on my dog's belly button?
No. A healed belly button needs no cleaning, ointment, or special care. If the skin in that area ever looks red, swollen, or irritated, skip the home products and ask your vet rather than treating it yourself.
The dog belly button is one of those small mysteries that makes you appreciate just how much is going on beneath that wagging, tummy-up bundle of fur. Loved this deep dive into canine curiosities?
