Do Male Dogs Have Nipples
Do Male Dogs Have Nipples
Yes, male dogs do have nipples. It might surprise some dog owners, but it’s completely normal and nothing to worry about. Just like in humans, both male and female dogs develop nipples in the womb before their sex is determined. These nipples remain throughout the dog’s life, even though they don’t serve any functional purpose in males. They’re a normal part of canine anatomy and can usually be felt along the underside of the chest and belly.
Why Do Male Dogs Have Nipples?
The reason male dogs have nipples comes down to basic biology. Nipples begin to form early in foetal development, before the embryo’s sex is determined. Once sex is established, female dogs go on to develop mammary glands, while male dogs do not. However, the nipples are already in place, and since they don’t cause any harm, they’re not "removed" by nature—they just remain as unused features.
How Many Nipples Do Male Dogs Have?
Male dogs typically have the same number of nipples as female dogs. The number can vary slightly between dogs, but most have between eight and ten nipples arranged in two rows down their chest and abdomen. The nipples are usually small, flat and inconspicuous, although they may be more noticeable in some breeds than others.
Should You Be Concerned About a Male Dog’s Nipples?
In most cases, there’s no reason to be concerned. Nipples on a male dog are harmless and don’t require any special care. However, if you notice changes—such as swelling, redness, discharge, lumps or your dog constantly licking one spot—it’s worth speaking to your vet. These symptoms could indicate an allergic reaction, infection or even, in rare cases, a tumour. Keeping an eye on your dog’s skin and knowing what’s normal for them is always a good idea.
Do Male Dogs Ever Get Mammary Tumours?
It’s very rare, but not impossible. Mammary tumours are far more common in unspayed female dogs, especially as they get older. Male dogs can occasionally develop similar lumps near the nipples, but it’s unusual. If you notice any new growths around your dog’s chest or belly, it’s important to have them checked by a vet, regardless of the dog’s sex.
Can You Accidentally Mistake Nipples for Ticks or Growths?
Yes, and it happens more than you might think. Especially in short-haired breeds, nipples can feel like small bumps when you’re grooming your dog or running your hands along their belly. This sometimes causes concern for owners who mistake them for ticks or skin problems. Once you know what they are and where they’re located, it becomes easier to identify them as harmless.
Summary
Male dogs absolutely do have nipples, and it’s completely normal. They serve no function, but they’re a leftover part of early development that both sexes share. Most of the time, there’s no need to give them much thought. Just make sure you’re familiar with what’s normal for your dog so you can spot anything unusual. If something doesn’t seem right, your vet is always the best person to turn to for reassurance or a proper diagnosis.
