Understanding the Basics
You may have noticed your male dog has nipples and this might have left you puzzled. Contrary to popular belief, male dogs, like all mammals, have nipples too. This is because the sex of a mammal isn’t determined until after nipples have already started to form.
The Role of Genetics
The formation of nipples in mammals occurs in the early stages of embryonic development, before the sex of the embryo is determined. This is why male dogs, and in fact all male mammals, have nipples. They are simply a part of the basic mammalian blueprint.
- Genetic Blueprint: All mammals, regardless of gender, follow a similar initial genetic blueprint. This includes the formation of nipples.
- Sex Determination: The sex of the embryo is determined later in the development process, which is why both male and female mammals have nipples.
Functionality of Nipples in Male Dogs
As you may have guessed, the nipples on male dogs serve no specific function. They are what scientists call “vestigial structures.” These are structures that have no apparent function in the current species but were possibly functional in ancestral species.
- Vestigial Structures: Examples include the human appendix and wisdom teeth, as well as the nipples on male dogs.
- Lack of Function: Unlike female dogs, male dogs do not need nipples for nursing puppies, so their nipples remain non-functional.

| Non-functional Nipples | Nipples that do not serve any purpose in the animal |
Nipple Health in Male Dogs
While the nipples on male dogs do not serve a specific function, it is crucial to keep an eye on them as a part of your pet’s regular health check. Changes in your dog’s nipples like swelling, discharge, or discoloration can be signs of health issues, including infections, allergies, or even cancer.

Q: Do all male mammals have nipples?
A: Yes, all male mammals have nipples due to the basic mammalian genetic blueprint.
Q: Can male dogs get breast cancer?
A: Yes, while it is rare, male dogs can get breast cancer.
Q: Why does my male dog have more nipples than my female dog?
A: The number of nipples varies among dogs and is not determined by gender.
