Yes, dogs absolutely have belly buttons — they just do not look anything like yours. Like humans, dogs are placental mammals, which means every puppy develops in its mother’s womb connected by an umbilical cord. Once that cord is severed at birth, a small scar forms on the puppy’s abdomen. That scar is the belly button. The reason most dog owners have never noticed one is that it heals into a tiny, flat mark that gets hidden beneath a layer of fur.
If you have ever wondered do dogs have belly buttons like humans, you are asking a question thousands of pet owners search for every month. It is one of those curious things about dog anatomy that seems obvious once you learn the answer, yet most people go their entire lives without ever seeing a dog’s navel. In this article, we will break down exactly what a dog’s belly button is, where to find it, how it differs from a human belly button, and when you should be concerned about potential health issues near that area.

What Is a Belly Button?
A belly button, or navel, is simply the scar that remains after the umbilical cord detaches following birth. During pregnancy, the umbilical cord is the lifeline between a developing fetus and its mother’s placenta. It delivers oxygen and nutrients from the mother’s bloodstream to the growing baby and carries waste products away.
Every placental mammal on Earth — including dogs, cats, whales, elephants, and humans — develops with an umbilical cord. That is over 5,000 species of mammals that all share this same biological connection to their mothers before birth. Once the cord is no longer needed, it is severed or falls off, and the small opening in the abdomen heals and closes. The resulting scar is what we call a belly button.
Do Dogs Have Belly Buttons Like Humans?
The short answer is yes — dogs do have belly buttons, but they look very different from the ones humans have. Humans have either innies (a small pit or depression) or outties (a tiny bump), and our belly buttons are fairly obvious because we have relatively little body hair covering that area. Dogs, on the other hand, end up with a small, flat scar that is barely noticeable even on short-haired breeds.
The difference comes down to how the umbilical cord is handled at birth. When a human baby is born, a doctor or midwife clamps and cuts the cord, leaving a stubby piece that shrivels up and falls off within a week or two. The wound heals inward, creating the characteristic indentation or protrusion.
With dogs, the process is different. The mother dog bites through the umbilical cord shortly after each puppy is born. This natural method of severing the cord happens much closer to the puppy’s body wall than a surgical clamp would. The small stump that remains dries up and falls off within one to three days, and the skin heals flat, leaving only a thin, barely visible line of scar tissue.
Where Is a Dog’s Belly Button Located?
A dog’s belly button sits on the midline of the abdomen, roughly between the bottom of the ribcage and the top of the pelvis. If you imagine a vertical line running down the center of your dog’s underside from chest to groin, the belly button is positioned along that line, closer to the ribs than to the hind legs.
On most dogs, it looks like a small, oval-shaped patch of slightly thinner fur or a faint vertical scar about the width of a fingertip. You might mistake it for a small scratch or a tiny blemish on the skin. On some dogs, especially those with light-colored or thin coats, you can spot it fairly easily if you know what to look for. On thick-coated breeds like Huskies or Golden Retrievers, you will almost certainly need to part the fur to see anything at all.
Why Are Dog Belly Buttons Hard to Find?
There are a few reasons most dog owners never notice their dog’s belly button. The biggest one is fur. A dog’s coat covers the abdomen completely, and the belly button scar is so small and flat that it blends right in with the surrounding skin. Unlike humans, who walk upright with their midsection exposed, dogs walk on all fours with their belly facing the ground, so even a visible belly button would not catch your eye from a normal angle.
Another factor is how quickly and cleanly the scar heals in puppies. Because the mother dog severs the cord so close to the body wall and the remaining stump detaches within days, there is very little tissue left to form a noticeable mark. Human belly buttons remain prominent partly because of how the cord is clamped and how the larger wound heals over time.
Some owners on Reddit and pet forums mention they searched for years without finding their dog’s navel. That experience is completely normal and does not mean anything is wrong. The scar is simply that subtle.
How to Find Your Dog’s Belly Button
If you want to see it for yourself, here is a simple step-by-step approach:
Step 1: Wait until your dog is relaxed and lying on its back or side, ideally during a belly rub session when your dog is calm and comfortable.
Step 2: Locate the bottom edge of your dog’s ribcage on the underside of the body. Move your fingers about two to three inches below the last rib, along the center line of the belly.
Step 3: Gently part the fur in that area and look for a small vertical line, a tiny dimple, or a patch where the fur grows in a slightly different pattern or direction.
Step 4: If you cannot see it, try lightly running your fingertip along the midline. You may feel a very slight ridge or indentation in the skin even if you cannot see anything visually.
Step 5: Do not press hard or poke. If your dog seems uncomfortable, stop and try again another time. Some dogs are ticklish or sensitive in this area.
Keep in mind that on puppies, the belly button may be slightly more visible because the fur has not fully grown in. As the dog matures and the adult coat fills out, the scar becomes even harder to spot.
Do Other Animals Have Belly Buttons?
Yes — all placental mammals have belly buttons. Cats, horses, cows, whales, and even elephants all carry the same umbilical scar from birth. Cats have belly buttons that look almost identical to a dog’s: a small flat scar hidden under fur on the midline of the abdomen.
The exception is non-placental mammals. Marsupials like kangaroos and koalas spend almost no time in the womb connected by an umbilical cord, so they do not develop a visible belly button. Monotremes like the platypus and echidna lay eggs rather than giving live birth, so they have no umbilical connection at all. This is a distinction worth knowing because it highlights just how universal the belly button is among mammals that develop inside a womb — including your dog.
Umbilical Hernias in Dogs: When to Worry
While the belly button itself is harmless and serves no function after birth, the area can sometimes develop a problem called an umbilical hernia. This occurs when the small opening in the abdominal wall where the umbilical cord passed through does not close completely after birth. A small piece of fat or intestinal tissue can poke through the opening, creating a soft lump under the skin near the belly button.
Umbilical hernias are fairly common in puppies. Many are small and close on their own by the time the puppy is about six months old. If you can gently push the lump back in and it does not seem to bother your puppy, your vet may recommend a watch-and-wait approach.
However, you should contact your veterinarian if you notice any of the following signs:
- A lump near the belly button that is growing larger over time.
- The lump feels firm or painful to the touch.
- Your dog is vomiting, lethargic, or refusing to eat.
- The skin over the lump turns red, purple, or dark.
These symptoms could indicate that the hernia has become strangulated, meaning the tissue trapped in the opening is losing its blood supply. This is a medical emergency that requires immediate veterinary attention. Many veterinarians repair umbilical hernias at the same time as a spay or neuter surgery to avoid putting the dog under anesthesia twice.
FAQs
Does a dog have a belly button?
Yes. Every dog has a belly button because all dogs are placental mammals. During development in the womb, each puppy is connected to its mother by an umbilical cord. After the cord is severed at birth, a small flat scar forms on the abdomen — that is the belly button.
Where is a dog’s belly button located?
A dog’s belly button is located on the midline of the abdomen, about two to three inches below the bottom of the ribcage. It sits between the ribs and the pelvis on the underside of the dog’s body, often hidden beneath the fur.
Can you see a dog’s belly button?
In most dogs, the belly button is very difficult to see. It heals as a small, flat scar that is covered by fur. On short-haired or light-coated breeds, you may be able to spot it by parting the fur along the midline of the belly. On thick-coated breeds, it is almost impossible to find without carefully parting the fur and feeling along the skin.
Is it okay to touch a dog’s belly button?
Yes, it is perfectly fine to touch the area where your dog’s belly button is located. There is nothing sensitive or special about the scar itself. However, if you feel a lump or your dog reacts painfully when you touch the belly area, schedule a veterinary checkup to rule out an umbilical hernia or other issue.
Do puppies have belly buttons?
Yes. Puppies are born with umbilical cords that the mother dog bites through shortly after delivery. The small stump that remains dries up and falls off within one to three days, leaving behind the belly button scar. In very young puppies, this scar may actually be slightly easier to see because the fur has not fully grown in yet.
What does a dog’s belly button look like?
A dog’s belly button looks like a small, flat, vertical scar or a tiny oval mark on the midline of the belly. It does not have an innie or outie shape like a human belly button. Instead, it is usually just a thin line of slightly different-colored skin or a small patch where the fur grows in a slightly different direction.
Final Thoughts on Whether Dogs Have Belly Buttons
So, do dogs have belly buttons like humans? They absolutely do — and for the exact same biological reason. Every dog that has ever lived was once connected to its mother through an umbilical cord, and every one of them carries a small scar on their belly as proof. The only real difference is that a dog’s belly button is a flat, faint scar hidden under fur, while ours is a more visible indentation or bump on a relatively hairless body.
Knowing where to find your dog’s belly button is not just a fun piece of trivia. It is also genuinely useful for monitoring your dog’s health. If you ever notice a lump, swelling, or redness in that area, it could be a sign of an umbilical hernia that needs veterinary attention. The next time your dog rolls over for a belly rub, take a moment to gently feel along the midline of their abdomen. You might just discover something you never knew was there.
