Why Do Male Dogs Have Nipples?
So What's Up With Nipples on Male Dogs?
So a friend of mine asked on social media if male dogs have nipples and someone commented: “If you need a dog with nipples just get a female.” I took up the commenter, and she asked me, “Why should a male dog have nipples?” Then another commenter wondered, "Why do human males have nipples?"
This sort of question can arise when people are not sure of things around them. In this article, we want to answer the question and discuss nipples in male dogs. For pet lovers, this is an interesting discussion to get you to know your best friend a little more!
Looking at most male mammals, one will notice that most of them have nipples with a few exceptions. And, you may wonder why. Dogs, as seen with most mammals, have male and female equipped with nipples. The male pooch nipples are seen lined neatly side-by-side running all through length of the torso. If you observe carefully, it’s almost the same with their female folks. Yes, just like human males with breasts. So what's up with nipples on male dogs, and most of all, what in the world are they used for?
A Cookie Cutter Explanation?
A commenter reasoned that perhaps our creator had some sort of mold made to manufacture different animals. Males and female must therefore have nipples because the same mold was used over and over in creating them before deciding on which one should be male or female based on the functions for each one in life.
Wow, what an argument? I want you to comment below what you think about this line of reasoning!
Not only do male dogs have nipples, but their nipples also happen to have names; meaning so much work has been done biologically to pay attention to the male dog nipples too. The nipples are in pairs like their female folks and, yup, they are named accordingly!
Trivia Question: How Many Nipples Do Dogs Have?
Here's a little piece of trivia for you: how many nipples do male dogs have? The number of nipples in male dogs tend to depend on the dog's over all size. Dogs may have eight or ten nipples which are called as follows:
For a ten-nippled dog, its nipples names will include:
- Two cranial thoracic nipples
- Two caudal thoracic nipples
- Two cranial abdominal nipples
- Two caudal abdominal nipples
- Two pair of inguinal nipples
Nipples as Decoration?
Why would someone create a feature not useful in a product? Ha-ha, sometimes it's best not to go on social media if you don’t want to get some funny thinking up your head with the kind of questions people ask… Why would a male have nipples that do not produce milk to feed its young like the females? Well, this is a very good question, that I am sure goes around nipples in men too.
"Nipples in male dogs are only a decoration," suggested a commenter. Well, it's not like male dogs like to put piercings on them, so the word decorative is a bit off as it reminds me of Christmas trees, but hey, that's what he said.
Turns out, there is really no explanation for their use and the only rational explanation that seems to cause one to think is the one that said animals were created equal from the factory setting. The cookie mold to form dogs must have been not gender sensitive. The dogs who got lucky to have female function are blessed with nipples producing milk, but ones with male function end up with a dry land under their belly. Nipples in male dogs are therefore destined to remain in what's known as a "rudimentary state." To put it bluntly, they are just buttons with no known function.
A Big Pile of Dough?
Let's take a bit a step back though shall we? A trip back into the womb, when puppies are in their embryonic state just floating about, shows us that nipples are already there in both female and male fetuses during their development.Just as one of the commenters said, pups being male or female are virtually the same as if they were actually taken from a big pile of dough and cut out into shapes by using the same exact mold.
By the way, for those skpetics out there, this is all backed up by claims by veterinarian Dr. Justin Lee who explains in his book: " It's a Dog's Life...but It's Your Carpet." how pups are basically made all the same in utero, until later on when powerful sex hormones kick in and start morphing them using a process known as "sexual differentiation." It is therefore only later in life that female sex hormones start taking off making male dogs and female dogs different.
In females, these hormones responsible for nipple changes reach their peak levels when the female dog gets pregnant and is just about getting ready to whelp or is undergoing what's known as a false pregnancy. These surges in hormones are what trigger nipple enlargement and the section of milk.
So there you have it, a biological explanation as to why female dogs have nipples. However, this does not remove the fact that male nipples are still there and are named the same as their female folks. Of course, the female nipples have defined a function, but male’s nipples still have none as we know it. Yet, it seems that Mother Nature must still feel they must have some purpose, otherwise one would assume that adaptive pressure would have wiped them out.
If you love dogs, why not join in this interesting discussion about why do male dogs have nipples? Take the time to examine your male dog nipples and tell us what you think? Or do your male dog’s nipples produce milk? Hopefully not,but keep me posted about your findings!
