Before they develop their male genitalia and the Y chromosome is outlined to distinguish a male from a feminine, all fetuses are inherently feminine.

At roughly 5 weeks gestation, puppies develop their intercourse organs. If the canine is a feminine, the mammary organs develop absolutely because of the additional X chromosome, and the mammary glands and nipples could be wanted to serve their organic objective, which is to supply milk and nurse their younger. If the canine is a male, the penis, testicles, and different male reproductive organs develop, however the mammary glands and nipples don’t go away as a result of they have been already there.
