The most important difference between male dogs and female dogs is their genitals. Compared with female dogs, male dogs have a penis bone. At the same time, the position of urination in female dogs is under the anus, while in male dogs, it is under the abdomen. Male dogs will have vaginal bones when they are born, a urethra opening under their belly, and testicles when they reach adulthood.

The genitals of a male dog are very close to the navel and far from the anus, almost on the belly; while the genitals of a female dog are very close to the anus, just below the anus, not close to the navel, and the female dog’s small breasts are very Clearly scattered on the belly. This method is the most reliable. The genitals of male dogs are mostly round, located in the middle of the belly; the genitals of female dogs are triangular, located below the anus.
