Inverted Nipple In Dogs (Should Pet Owners Be Worried?)

As dog owners, examining your dog physically at home is crucial to look for any anomalies.

What if you noticed that your dog’s nipple appears upside down?

Do you have cause to be concerned about this?

Both male and female dogs are capable of developing an inverted nipple. Pregnant or nursing dogs are more likely to develop this condition. Although an inverted nipple is typically just a cosmetic concern, some dogs may have health issues due to it.

Beyond its intriguing appearance, knowing the causes and effects of a dog’s inverted nipple can be essential to ensuring your dog’s overall health.
Basically, an inverted nipple is one that points inward or rests flush against your dog’s belly. The retracted nipple is another name for it.
It can appear in one or more nipples and is a different color from the regular one.
Due to their dogs’ fur covering most of their nipples, most dog owners don’t notice this problem on their pets.

Why Does My Dog Have An Inverted Nipple?

Here is a closer look at the causes of this particular condition.

Mammary Tumor

Dogs’ mammary glands can develop abnormal growths called mammary tumors.
Although male dogs can experience this problem, it is extremely uncommon and tends to affect female dogs more frequently.
Mammary tumors are more likely to develop in female dogs who are not spayed or who are spayed later in life after several heat cycles.
The nature of these growths can range from benign to malignant.
These signs include:
  1. A growth or lump
  2. Bleeding
  3. Discoloration
  4. Flipped nipple
  5. Reduced appetite
  6. Unaccounted-for weight loss
Take your animal as soon as possible to the vet for testing if you have reason to believe it may have a mammary tumor.

Traumatic Events

Traumatic experiences can also lead to inverted dog nipples
Accidental, rough play or combat-related physical injuries to a dog’s nipple can cause it to retract or invert.
Mammary surgeries can accidentally result in inverted dog nipples, especially if they are not performed carefully.
The skin in this area may also contract as it heals from chemical or thermal burns, leading to nipple inversion.

Nursing Or Pregnant Dogs

Inverted Nipple In Dogs
When they are pregnant or nursing their puppies, female dogs are more likely to have inverted nipples.
This is brought on by the physiological and hormonal changes that their bodies are going through.
Puppies can be very aggressive when attempting to get milk from their mothers because they are so ravenously hungry.
This could injure the nipple and risk damaging it or turning it inward.

Are Inverted Nipples In Dogs A Health Problem?

The majority of dogs don’t experience any health risks from having an inverted nipple; it is simply an aesthetic issue.
However, there are a few situations in which your dog may experience some difficulty due to inverted nipples.


The inverted nipple becomes infected when a dog has mastitis.
Although there is a higher risk because of how the nipple is positioned, not all inverted nipples will become infected.
Since the mammary glands become infected, this is more typical in nursing dogs. However, this condition can also affect male dogs or female dogs that aren’t nursing.
Infected inverted nipples in dogs are typically brought on by bacteria or other pathogens.
Dogs with mastitis will experience some pain and discomfort. Here are a few typical signs:
  • Redness and swelling
  • Discharge
  • Crusty looking nipple
  • Weight loss
  • Lethargy
  • Refusing to nurse the puppies
The most obvious symptom would be a swollen, crusty-appearing nipple.
The best course of action is to take your dog to the veterinarian so the infection can be treated.
The infected nipple will need to be cleaned properly by the veterinarian, and antibiotics may be needed to get rid of the infection.
More importantly, dogs can die from severe mastitis.
If left untreated, the bacterial infection may begin to septicize and affect the dog’s other important organs.

Inverted Nipple On Nursing Dogs

Making sure that their puppies are fed properly is the full-time job of intact female dogs who are nursing their pups.
Because it is much more difficult for the puppies to suckle on an inverted nipple, it can be a problem if she has an inverted nipple or nipples.
Think about a female dog having a litter of six puppies with two of her nipples inverted. As a result, only four puppies can be fed at once.
Puppies need to be fed constantly, and if they don’t get enough nutrients, their growth may be stunted and they may develop other health issues.
If some of the more powerful pups are ‘nipple guarding’ the best milk-producing nipples, the situation could get worse.
Working closely with your veterinarian during this time will help you to quickly address any nursing issues and ensure the safety of the mother dog and her puppies.
Dog owners can take a few steps to make sure that all of the puppies are properly nursed.

The daily weight of puppies is being measured.

Every day, be sure to weigh each puppy and note the results. This will help you identify the puppies that need more time to eat because they are underweight.
It is simple to identify puppies who have been hoarding their mother’s nipples by tracking their weight gain.

Shift The Puppy

Keep a close eye out for ‘nipple guarding’ behavior when the puppies are sucking on the nipples.
These puppies will exhibit aggressive behavior, such as growling when another puppy tries to take over the nipple, or defensive body language.
Once these pups have been nursed, take them away and place the less dominant pups at the nipple so they can feed.

Invert The Nipples If You Can

By gently pulling on it or compressing the area around it, it might be possible to attempt to reveal the inverted nipple.
Try putting a larger, more powerful pup at the inverted nipple; it might be able to suction it out.

Feed the larger puppies by hand

Try feeding the larger, heavier puppies by hand as one way to control the litter.
Not feeding them is definitely a bad idea because they still need to be fed every day.
The normal nipples are made available for the weaker or smaller puppies to eat on when the heavier puppies are hand-fed.
If the female dog isn’t producing enough milk for the entire litter, this method works well.
You shouldn’t just give your puppy any milk. Get the right milk formula by first speaking with your veterinarian.

How To Clean An Inverted Nipple In My Dog?

The inverted nipples should always be kept clean to avoid getting any kind of infection.
You’ll need to clean it frequently in order to keep it clean.
Even if your dog has never had a problem with inverted nipples, it is still wise to visually inspect them once a week to make sure there is no swelling or discharge.
However, you should make it a point to clean the inverted nipples if you are aware that your dog is susceptible to mastitis.
The inverted nipples on your dog can be easily cleaned.
Wiping them clean with a damp cloth or wet wipes is the simplest way to clean inverted nipples.
Make sure to use pet-friendly wet wipes whenever you need to use them.
Avoid using wipes with alcohol or fragrance because those ingredients can irritate your dog’s skin.
The skin around your dog’s nipples and elsewhere is extremely delicate.
By applying pressure to the sides and cleaning off any debris that has accumulated there, you can reveal the inverted nipple.
After that, make sure to completely dry the area with a dry cloth. Bacterial growth is encouraged by residual moisture.
If your dog’s nipples are prone to infection, your veterinarian may also provide you with a cleaning solution to use.
On the inverted nipple, some dog owners have noticed large blackheads growing.
You should take your dog to the vet to have the tooth extracted rather than trying to do it yourself, in my opinion.
Your dog might experience pain and discomfort if you squeeze the blackhead too tightly.
Furthermore, if the blackhead isn’t properly removed, the nipple is more likely to become infected.
If the blackheads return on your dog, you can ask the veterinarian to demonstrate how to properly remove them.

Should I Correct the Inverted Nipple on My Dog?

Many dog owners may be concerned if they find out their dog has inverted nipples, but this condition is typically more of a cosmetic than a health issue.
If the inverted nipples are not infected, there is no need to treat or fix them.


Dogs’ nipples only have one purpose: to produce milk and feed their puppies when they are malnourished.
Inverted nipples in dogs don’t need to be fixed or treated unless they pose a health risk.
Make it a point to clean out the inverted nipple frequently if your dog is prone to mastitis or if it tends to gather a lot of debris and dirt to avoid a bacterial infection.
Keep in mind that severe cases of canine mastitis can be fatal, so if your dog has this condition, you don’t want to ignore it.
Otherwise, just accept your dog’s inverted nipple as a characteristic of their oddity.


What breeds are more prone to inverted nipples in dogs?

Any breed may develop inverted nipples, but Bulldogs, Pugs, and Dachshunds are among those where it is more prevalent.

Can inverted nipples be a sign of a more serious health issue?

Even though inverted nipples may not be particularly alarming in and of themselves, they occasionally point to underlying medical conditions. For an accurate assessment, you must speak with your veterinarian.

Is it possible for inverted nipples to resolve on their own?

Inverted nipples occasionally correct themselves as the dog ages, particularly when they are young puppies. However, it’s still a good idea to get advice from a veterinarian.

Can I prevent inverted nipples in my dog?

Given that genetics can have an impact, it might not always be possible to prevent inverted nipples. However, it’s crucial to maintain your dog’s general health through good nutrition and routine medical exams.
