We as humans have pretty obvious belly buttons; it is rare to meet someone with one you cannot see. But one question that people are often confused about is; do dogs have belly buttons? They still have the umbilical cord while in the mother, so they must have a belly button, right? Well, yes, they do. All animals that use a placenta while in the mother have belly buttons; they are used for delivering nutrition and oxygen and removing waste from the babies while in the uterus.
However, they are much more difficult to find than our four-legged friends. A belly button is essentially just a scar from removing the umbilical cord, and scars are extremely difficult to find on animals with long furs, such as cats and dogs. Furthermore, they are pretty small, too. If you look closely enough, you may see a darker skin patch or fur just under your dog’s ribcage. If you find it too easy, it can be a herniation, an outie belly button on humans, and you should take your dog to the vet as soon as possible if you start to notice that.
