How Many Nipples Do Male Dogs Have?
Both male and female dogs have nipples, much like humans. In fact, they have between 8 to 10 nipples. Since female dogs have nipples for obvious reasons, you may wonder “Why do male dogs have nipples?”. Well, many male mammals, including humans, have nipples. Scientist believe that the reason for that is natural genetic selection. Or, rather, the lack of it.
Since males and females start identical in the utero, nipples are, sort of, the default model for mammals. Even though they serve virtually no function in males, they also do not present any problems.Put simply, natural selection had no reason to get rid of the nipples. The only thing that might be concerning is petting your dog and discovering a lump on their belly, thinking it might be a tick. While you should check it out, it might just be a nipple you overlooked.
