What are Belly Buttons or Navels?

We all dog lovers must have wonder for once in life if dogs have navels just like us humans? Hence, let us start by understanding what bellybuttons or navels are exactly? In humans, the navel is a concave or convex portion on the abdomen above the waist. The concave type is also known as innies is the most common type with 90%. The rest 10 have convex types also known as outies.  The Navel may also be simply a blister that is forming where a person is connect to the umbilical cords. At the time of gestation. Let’s get information about the dog belly button.

When a baby is in the mother’s womb, the umbilical cord acts as a source of food and oxygen and also acts as an outlet for wastage from the baby to the mother. One side of the umbilical cord is attach to the placenta of the mother and the other to the centre of the baby’s stomach.

As the gestation progresses, the placenta grows into an organ that takes care of all such functions. When the baby is born and begins to breathe on its own, the umbilical cord detaches and is properly secure. As days pass by, this leftover secure part of the umbilical cord decays away and what is left over is the scar that is known as the belly button.

Do all mammals have belly buttons?

This entire process of development and birth is common to all mammals and is not limit to human beings only. You may find belly buttons on cats, dolphins, dogs and human beings. However, two mammals are exceptions to this process. First is the Marsupials that is a pouch animal similar to possums and kangaroos, which has a uterus and placenta.  However, the placenta of this mammal is similar to a Yolk cyst and the baby is connecting with it for a small time. Later, the baby shifts over to the pouch where it gains its nourishment from its mother’s teat while it completes the development process and during the process, the umbilical cord dissolves away.

Monotremes is another exception amongst mammals. Similar to the Platypus, the Monotremes too are egg-laying mammals. As there is no umbilical cord involve, there is no blister form and hence they have no belly buttons.

When it comes to dogs, the puppies are born in cysts that are fill with fluids. The newborns are connecting to their mother’s placenta through the umbilical cord. When the puppies are out of the uterus, their mother nibbles on and tears away the umbilical cord of each puppy. In a few days, time leftover butts break off and only a small blister is left. This is known as the dog belly button.

This umbilical butt in dogs is evident only for some time and it gradually disappears with time. What is left over is only a small incision and not a bigger hole as that in human beings? This is simply because the umbilical cord in human beings is larger as compare to dogs and so is the belly button.

We have discuss above that the belly buttons in the dogs are very small incisions. In human beings, these are like a hole or a butt and are evident. In the case of dogs, there are small blisters only.

Where do you find them on dogs?

As in human beings, the belly button is on the abdomen, similarly, in dogs, you can find it in the abdomen centre of dogs. It is locate near the little bunch of hair, where the dog’s coat meets close to the rib cage. In most dogs, it is simply a small blister or round crease. In some dogs, the hair on the stomach may form a circular shape or there may be a bunch of hair close to the belly button.

Many times it is difficult to find it even while you are looking at the right spot. In such a case, it is good to feel the blister by placing your fingers over the area. When you feel a small stiff knot on the skin, you would have place your fingers in the right place to find it.
