Do Dogs Have Belly Buttons?

Do dogs have belly buttons

The American Kennel Club explains that humans and dogs are placental mammals: the embryo develops in the uterus and is attached to the placenta by an umbilical cord. After birth, that cord no longer supplies oxygen or nutrients. In puppies, the mother typically tears open the birth sac, licks the puppy, and chews the cord, leaving a small stump that dries and falls off a few days later. The scar that remains is the belly button (umbilicus).

Dog navels are harder to see than human ones. AKC notes two reasons: abdominal fur, and a smaller, flatter scar because a puppy’s cord is much smaller than a human baby’s. It usually does not pop out or sink in the way a human navel does.

Common reasons

To find it, AKC says to look in the middle of the abdomen, just beneath the rib cage, for a tiny vertical scar, wrinkle, or a whorl of fur. You may feel a firmer spot of scar tissue if you cannot see it. If touching the stomach seems painful, contact your veterinarian.

A typical navel is only a leftover scar — it has no ongoing function. Variation in how obvious it is comes from coat length, color, and how the stump healed, not from a “missing” belly button.

Normal vs concerning behavior

What owners can do

Gently part the fur on the mid-belly when your dog is relaxed. A stable, tiny scar needs no home treatment.

If you feel a bulge, do not try to diagnose or “push it back” as a DIY fix. Note what you see and have a veterinarian examine it.

When to call a vet or trainer

See a veterinarian for any bulge at the belly button, pain when the abdomen is touched, discharge, or a lump that changes. AKC advises that hernias should be checked because trapped tissue can lose blood supply. Your vet can decide whether monitoring or further treatment is appropriate — that decision is individual, not a home call.

A trainer is not needed for belly-button questions unless you are practicing calm handling for vet exams.
