Male dogs have nipples, just like females, although they don't develop mammary glands.
Male dogs typically have 10 nipples, located along their belly, and they're usually smaller than those on female dogs.
These nipples are present from birth and remain throughout their lives, even though they don't produce milk or mammary tissue.
Male dogs develop nipples as a result of their embryonic development, where both males and females have a common precursor to the reproductive and urinary systems.
Health Issues Related to
Health issues related to male dogs' nipples are relatively rare, but it's essential to be aware of the potential concerns.
Mammary gland tumors can occur in male dogs, especially those over the age of 10. These tumors are usually benign and can be treated with surgery.
Infected nipples in male dogs can be caused by infectious organisms, leading to inflammation of the mammary glands. This can result in swollen, red, and painful nipples.
Swollen or discolored nipples can sometimes be due to parasites, allergies, or dermatitis. In rare cases, elevated levels of estrogen, which can be associated with testicular tumors, may also cause sudden discoloration of the nipples.
Here are some potential health issues related to male dogs' nipples:
- Mammary gland tumor
- Infected nipples (mastitis)
- Swollen or discolored nipples due to parasites, allergies, or dermatitis
- Hyperestrogenism (elevated levels of estrogen) associated with testicular tumors
Nipple Problems
Male dogs can experience nipple problems, but it's rare.
Most cases of nipple problems in male dogs are caused by well-intentioned but misguided attempts to remove a tick, which can lead to inflammation and infection.
Symmetry is key to evaluating your male dog's nipples - they should look about the same on both sides of the belly crease.
The nipples tend to increase in size as they move down the body, so a larger nipple near the groin is not necessarily a problem.
Compare the two nipples of a pair, not one nipple to every other nipple, to determine if there's a cause for concern.

It's unlikely that two ticks will coordinate and land on your pet's belly, but it's possible to find other nipple-like things in the area, such as skin tags or bug bites.
These will usually violate the symmetry rule, so if you notice any unusual nipple growth or changes, it's always best to consult a veterinarian to rule out any severe conditions.
Dog Anatomy
Male dogs, like most other male mammals, have rudimentary nipples and mammary glands.
These nipples appear as small, rounded bumps that can be flesh colored or pigmented, and are usually situated along the dog's lower abdomen.
The exact number of nipples can vary, but most dogs have about 10 nipples arranged in symmetrical pairs spanning from the chest to the groin.
Male dog nipples are generally smaller and less prominent than their female counterparts, primarily because they do not undergo the physical changes associated with pregnancy and nursing.
They can be more challenging to spot in some breeds, especially those with dense fur or overweight.
Male nipples are one of several vestigial body parts, like the appendix, that serve no purpose.
During embryonic development, all mammals initially follow a similar blueprint, which includes the formation of nipples.
It's not until later in development that the sex of the embryo influences the differentiation of sexual organs, which is why both males and females have nipples.
Since having nipples poses no significant disadvantage to males, there has been no evolutionary pressure to eliminate them from male mammals.
Male dog nipples are usually small, round, and maybe of a similar color to the dog's skin, making them somewhat inconspicuous.

Nipple Appearance
Male dogs' nipples are generally small and look like pimples, often pigmented with the same color as their flesh.
They can range in color from pink/tan to brown/black, depending on the dog's breed or color.
Nipples on male dogs should never be swollen, red, oozing, or tender, as this would be a cause for a vet visit.
Male dogs typically have 5 sets of nipples, which are named: cranial thoracic, caudal thoracic, cranial abdominal, caudal abdominal, and inguinal nipples.
The nipples on a male dog are usually found in the following areas: chest and abdomen, with the inguinal nipples located in the groin area.
