Inverted Nipples in Dogs

If you have a dog, you may have noticed that some of their nipples are inverted or retracted. This means they are not protruding outwards but rather tucked inside the skin.

You may wonder if inverted nipples in dogs are normal or if they pose any health risks for your furry friend.

This article will explain what inverted nipples are, why they occur in dogs, and when you should be concerned about them.

What are inverted nipples in dogs, and why do they occur?

Inverted nipples are nipples that are turned inward instead of outward. They can occur in both male and female dogs but are more common in females. Inverted nipples can be present from birth or develop later in life due to various factors, such as:

  • Genetics: Some dog breeds are more likely to have inverted nipples due to their hereditary traits. For example, bulldogs, pugs, and boxers are known to have inverted nipples more often than other breeds.
  • Hormones: Hormonal changes can affect the shape and size of your dog’s nipples. For instance, during pregnancy, lactation, or heat cycles, your dog’s nipples may become enlarged or swollen. This can cause some of them to invert or retract.
  • Aging: Their skin may lose elasticity and sag as your dog ages. This can also affect their nipples and make them appear inverted or sunken.

Are inverted nipples normal in dogs?

In most cases, inverted nipples in dogs are normal and harmless. They do not affect your dog’s health or function in any way. They are cosmetic variations requiring no treatment or intervention. However, there are some situations where inverted nipples can indicate a problem or cause complications for your dog. We will discuss these in the next section.

When should you be worried about your dog’s inverted nipples?

Although inverted nipples are usually not a health threat for dogs, there are some signs and conditions that you should be aware of and watch out for. These include:

1. Infection or inflammation

If your dog’s inverted nipples become red, swollen, painful, or discharge pus or blood, they may be infected or inflamed. This can happen due to bacteria, fungi, parasites, or foreign objects entering the nipple opening. Infection or inflammation can also spread to the surrounding tissues and cause mastitis or mammary gland infection.

2. Tumors or cancer

If your dog’s inverted nipples develop lumps, bumps, growths, or changes in color or texture, they may be affected by tumors or cancer. Mammary tumors are one of the most common types of cancer in female dogs. They can be benign or malignant and can affect one or more nipples. Male dogs can also develop mammary tumors, but they are rare.

3. Nursing difficulties or complications

If your dog is pregnant or nursing puppies, their inverted nipples may pose challenges or risks. For example, their puppies may have trouble finding or latching onto their nipples to feed. This can result in poor nutrition and growth for the puppies. Alternatively, their puppies may bite or scratch their nipples to stimulate milk flow. This can cause injury and infection for the mother.

If you notice these signs or conditions in your dog’s inverted nipples, consult your veterinarian as soon as possible. They can diagnose the problem and prescribe your dog the appropriate medication and treatment plan. Depending on the severity and type of the issue, your dog may need antibiotics, anti-inflammatory drugs, painkillers, surgery, chemotherapy, radiation therapy, or other interventions.

How to care for your dog’s inverted nipples?

To keep your dog’s inverted nipples healthy and comfortable, you should follow some general guidelines and tips. These include:

1. Cleaning and inspecting your dog’s nipples regularly

It would help to gently wash your dog’s nipples with warm water and mild soap once a week. This will help remove any dirt, debris, or bacteria that may accumulate in the nipple opening. You should also check your dog’s nipples for signs of infection, inflammation, tumors, or cancer. If you find anything abnormal or suspicious, contact your vet immediately.

2. Avoid harsh or abrasive materials that irritate your dog’s nipples

You should use soft and natural fabrics to dry your dog’s nipples after cleaning them. You should also avoid using rough towels, brushes, combs, clippers, scissors, or other tools that can scratch or damage your dog’s nipples.

3. Providing adequate nutrition and hydration for your dog

It would help to feed your dog a balanced, high-quality diet that meets their nutritional needs. You should also ensure they have access to fresh and clean water at all times. This will help maintain their overall health and immunity and prevent any deficiencies or diseases that can affect their nipples.

4. Monitoring your dog’s behavior and mood for any changes or discomfort

It would be best to observe it for any signs of pain, distress, or discomfort related to their nipples. For example, if your dog is licking, scratching, biting, or rubbing their nipples excessively, they may be irritated or infected. If your dog is lethargic, depressed, or uninterested in food or play, they may be sick or in pain. If you notice these signs, you should take your dog to the vet for a check-up.


Inverted nipples in dogs are not uncommon and are usually not a cause for concern. They are a cosmetic variation that does not affect your dog’s health or function. However, there are some situations where inverted nipples can indicate a problem or cause complications for your dog. Therefore, you should be aware and attentive to your dog’s inverted nipples and seek veterinary advice if you have any questions or concerns. Following the tips and guidelines in this article can help keep your dog’s inverted nipples healthy and comfortable.
