The simple answer is yes. Almost all mammals have a belly button including our dogs. Although you may not be able to see a dog’s belly button as it is usually covered in fur.
However, if you really want to find it, look for a thin, flat scar just above the base of your dog’s ribs where the fur meets in the middle.
Sometimes you may notice that your dogs fur grows in a particular pattern in that region and it’s usually right around where the navel is.
Why do dogs have belly buttons?
As dogs are mammals they give birth to live young. So when the puppies are developing in the womb they are dependent on their mothers not only for nutrition but also for oxygen.
These essentials are provided via the umbilical cord which is a flexible tube that connects the mother via her placenta to her puppy via its stomach.
This tube not only carries oxygen, food and nutrients to the puppy but it also carries waste away from the puppy back to the mother so that she can dispose of it.
Once the puppy has been born the mother chews through the umbilical cord. And a flat scar is all that marks the spot where the umbilical cord was once attached.
Why can’t I see my dogs navel?
If you have ever seen a new born puppy the belly button is much more noticeable, however it disappears quickly.
The umbilical cord is very small and it heals extremely quickly into a flat thin line unlike our complicated navels.
Within a few days it gets completely covered in fur and as long as there are no complications we may never see it again.
Herniated belly button
Occasionally a puppy’s belly button is obvious. This is not usually a good sign but instead suggests a herniated belly button, or also called an umbilical hernia.
It can appear as a lump or bulge in or near the belly button. It may look bigger or smaller depending on what your puppy is doing.
In the womb the umbilical cord passes into the puppy’s stomach through a small opening in the stomach muscles.
A hernia occurs when the stomach muscles do not heal properly and the tissue or intestines poke through this weak spot at the belly button.
If you do notice that your puppy or even your adult dog has a noticeable bulge near where his navel should be, do get it checked.
Although they do sometimes heal by themselves it’s better to get it checked by a professional.
