1 Have you ever been intrigued by your navels? All people have one. Do animals also have?
2 Many animals yes. Dogs and cats have them. Like cows and elephants. Even some animals that live in the water have navels, such as whales and dolphins. All these animals and people are mammals.
3 Frogs, fish, lizards and birds have no navels. They are not mammals. There are many other animals that are not mammals either. Only mammals have belly buttons.

Do dogs have belly buttons?
We will not be around. Dogs do have a navel. As mammals, they have a scar that indicates that in their embryonic phase it was fed through the mother's placenta. Now, why does this doubt arise?
Normally, the navel of dogs is not visible due to the layer of hair that surrounds it. That is why many dog owners wonder if they have a navel or not.
Why do dogs have a belly button?
The navel is a characteristic characteristic of mammals, that is, those species that feed on breast milk. Within this group, placental viviparous are the beings that arise from the fecundation of the mother's womb and that feed through the placenta. To make this possible, there is a duct that directly connects the placenta with the embryo, providing the necessary nutrients for its development while it is in the womb.
When the dog is born, that duct, also called umbilical cord, is plucked by the mother naturally. In some cases, a piece of cord may remain for a while, which will fall off without us having to intervene. When the umbilical cord is cut too close to the skin, it can cause a small hernia that will cause the belly button to heal like a lump or lump.
In short, we can say that the navel is the scar that the dog has left after the umbilical cord falls.
Where do dogs have their navel?
Dogs have the navel in the same place as humans. This is, between the genitals and the breasts. However, it is normal that you do not locate it with the naked eye, since it is normally covered with a dense layer of hair.
In other cases, depending on the problems that have arisen while the umbilical cord is detached, the navel can be bulky or in "relief." In those cases, its location will be much simpler.
Do all animals have a navel?
The umbilical cord is a small organic "tube" that is responsible for facilitate the transport of oxygen and nutrients to the offspring during the gestation period. After birth, the cord is removed, cut or falls over the days, as it is no longer necessary. The place where the cord was closed leaving a mark, which we know as "the belly button"Now, you surely recognize it as a human brand, but do other animals have it? The answer is yes but not all.
What are the animals that have a navel?
- Mammals: Mammals are vertebrate animals that have warm blood and feed on breast milk during the first days of life. They are animal mammals such as giraffes, bears, kangaroos, mice, dogs and thousands of others.
- Viviparous: Viviparous animals are those that are born from an embryo that develops after fertilization in the womb. In the belly they feed on the nutrients and oxygen they need while their organs are formed. Although many navel animals are viviparous, not all viviparous animals have a navel, for this, the following condition must be met.
- Placental viviparous: All placental viviparous have a navel, that is, those animals whose embryo develops in the mother's uterus, while they are fed by the placenta through the umbilical cord.
In most animals that are placental viviparous, the scar following the umbilical cord fall is very small, faint. In addition, some have a lot of hair, which makes it difficult to find that brand.
Navel related diseases
Believe it or not, there are some health problems related to the navel, the most common is umbilical hernia in dogs. It appears during the first days of life and manifests as a hard lump in the belly area. Sometimes it is recommended to wait approximately six months for the body to reduce it, but after that time you can opt for surgery or the treatment recommended by the veterinarian.
Most umbilical hernias do not represent a problem that should be addressed urgently, but you should not neglect them either. On some occasions, it is possible to eliminate the female sterilization at the time.
Despite this, some dogs may require intervention for these hernias. Remember to follow all the recommendations of the vet and go to the office for any abnormal behavior of your furry friend. In addition, we offer some recommendations for those dogs that have undergone surgery of this type:
