If you have ever given your dog a good belly rub, you might have found yourself squinting at their tummy and wondering: do dogs have belly buttons? It is one of those questions that sounds silly until you actually go looking and cannot find one.
The good news is there is a simple, reassuring answer, along with one important thing every owner should know about the odd lump that sometimes appears in the same spot.
Yes, dogs do have belly buttons. Like all placental mammals, puppies are attached to their mother by an umbilical cord in the womb, and the belly button is simply the small, flat scar left behind once that cord dries up and drops off. It sits on the midline of the tummy, just below the ribcage, and is usually hidden by fur.
Key Takeaways
- All dogs have belly buttons, because every placental mammal is nourished by an umbilical cord before birth.
- A dog’s belly button is a flat, healed scar, not the protruding “innie” or “outie” people have.
- You will find it on the midline of the belly, roughly below the ribcage, often surrounded by a small swirl of fur.
- It is hard to see because it is flat and covered by hair, so most owners never spot it.
- A soft bulge in that spot may be an umbilical hernia, which is common in puppies and worth a vet check.
- Most small hernias are harmless, but any bulge that grows, feels warm or painful needs prompt veterinary advice.
Do Dogs Really Have Belly Buttons?
Absolutely. A belly button, or navel, is nothing more exotic than the mark left where the umbilical cord was once attached. Before a puppy is born, that cord carries oxygen and nutrients from the mother and takes waste away, keeping the developing pup alive inside the womb.
When the puppy is born, the mother chews through the cord, leaving a short stump. Over the following few days that stump dries out and falls away, and the tiny wound heals into a flat scar. That scar is your dog’s belly button. Every dog has one, whether you can find it or not.
This is the same anatomy that gives dogs their other undercarriage features. If you have ever counted the rows of teats along your dog’s tummy, you will find the navel tucked in among them. We cover the nipple side of things in our guide to how many teats a dog has.
Where Is a Dog’s Belly Button and What Does It Look Like?
A human belly button sits smack in the middle of the abdomen and is impossible to miss. A dog’s is far more discreet. Look along the midline of the tummy, roughly where the belly begins just below the ribcage, and that is your target area.
Rather than a deep dimple, a dog’s navel usually looks like a thin, flat scar or a small horizontal fold or pucker of skin. In many dogs it is marked by a little swirl or patch of fur that grows in a slightly different direction or colour to the surrounding coat. On a puppy it can be a touch more obvious, but it fades and becomes harder to make out as your dog matures.
Why Is a Dog’s Belly Button So Hard to See?
There are three reasons most owners have never spotted their dog’s navel.
First, it is flat. Unlike people, dogs do not develop a prominent “innie” or “outie”, so there is no obvious hole or bump to catch your eye. It is simply a healed scar sitting flush with the skin.
Second, it is covered in fur. Even short-coated breeds carry a decent layer of fuzz across the belly, which neatly hides the scar. Unless a dog has been clipped for surgery, the coat does an excellent job of camouflage.
Third, it can shift out of clear view on adult dogs, especially females who have had a litter and carry a looser, pouchier tummy. Can you feel it? Sometimes, with a gentle press along the midline, you may notice a very slight difference in the skin, but on many dogs there is nothing obvious to feel at all. That is completely normal.
What the Belly Button Actually Is
To be clear, the belly button is not an organ or anything with an ongoing job. It is purely a remnant, the healed-over point where the umbilical cord and placenta once connected the puppy to its mother.
Once a puppy is born and breathing, eating and circulating blood on its own, the cord has done its work and is no longer needed. The stump drops off within a few days, and the belly button is all that is left as a permanent reminder of those first weeks of life. This is exactly the kind of quirky anatomy that makes dogs fascinating, much like the question of whether dogs have lips.
The Important Bit: Umbilical Hernias
Here is the part every owner should read. While a normal belly button is flat, sometimes there is a soft, squishy bulge in that same spot. That is not a fancy “outie”, it is usually an umbilical hernia, and it is one of the most common minor conditions seen in puppies.
An umbilical hernia happens when the umbilical ring, the small opening in the abdominal wall where the cord passed through, does not close up fully after birth. A little abdominal fat, or occasionally a bit of tissue, then pushes through the gap and sits under the skin as a small lump. It is often something a breeder or vet first notices during an early check.
Many small hernias are harmless. Vets often report that little ones may close on their own by around three to four months of age, and plenty of dogs live happily with a small, soft hernia that never causes a problem. In many cases, if surgery is needed, it can be tidied up at the same time as neutering.
The reason it matters is that, in rare cases, a larger hernia can allow a loop of intestine or other tissue to slip through and become trapped. If the blood supply is cut off, this becomes a genuine emergency. Warning signs include a bulge that suddenly gets bigger, feels firm, hot or painful, or a dog that is vomiting, off their food or clearly unwell.
The sensible rule: any lump or bulge around your dog’s belly button should be checked by a vet. Only a professional can tell the difference between a harmless little hernia and one that needs surgical repair, so never try to push a bulge back in or diagnose it yourself. Booking a check is a normal part of responsible ownership, alongside the everyday steps in keeping your dog healthy. It is also worth remembering that hernia repair is one of the potential vet bills to plan for when you look at the wider cost of owning a dog.
Frequently Asked Questions
Where is a dog’s belly button?
It sits on the midline of the tummy, roughly below the ribcage where the belly begins, tucked in among the rows of teats. On most dogs it is a small, flat scar hidden by fur rather than an obvious dimple.
Do dogs have outies?
Not in the way people do. A healthy dog’s belly button is flat, not a raised bump. If you can see or feel a protruding lump there, it is far more likely to be an umbilical hernia than a true “outie”, so it is worth a vet check.
Can you feel a dog’s belly button?
Sometimes you can feel a very slight scar or fold with a gentle press along the midline, but on many dogs there is nothing obvious to feel. Both are perfectly normal. What you should never ignore is a soft or firm bulge in that area.
Do puppies have belly buttons?
Yes, and they are often a little easier to spot on a young puppy before the fur thickens and the scar fades. In the first days of life you may even see the drying stump of the umbilical cord before it drops off. New puppy owners can find plenty more in our guide to when puppies calm down.
Do all animals have belly buttons?
No. Only placental mammals, such as dogs, cats and humans, have belly buttons, because only they are nourished by an umbilical cord and placenta. Marsupials like kangaroos and egg-laying monotremes like the platypus do not, so belly buttons are actually a mammal club with a strict membership.
The Bottom Line
So, do dogs have belly buttons? Yes, every single one, even if you will probably never find it under all that fur. It is simply a small, flat scar from the umbilical cord, sitting quietly on the midline below the ribcage.
The only time it needs your attention is when it is not flat. A soft or growing bulge in that spot points to an umbilical hernia, which is common, usually minor, but always worth mentioning to your vet. Beyond that, you can happily get back to the belly rubs your dog was demanding in the first place.
