Sex

Like other dogs, Formosan Mountain Dogs typically reach sexual maturity between 6 and 12 months, however, this schedule might vary from one dog to another. Male dogs may start producing sperm and show symptoms of sexual activity around this time, while females are receptive to mating when they begin their first heat cycle.

Because of her physical immaturity, which might affect her preparedness for pregnancy and motherhood, it is not recommended to breed a female during her first heat cycle. To ensure the safety of both the dogs and their future generations, it is essential to breed responsibly, which includes doing health screenings and genetic testing.

While it's true that most dog breeds achieve sexual maturity between 6 and 12 months, the general consensus is that you should wait until your Formosan Mountain Dog is at least 1 or 2 years old before you think about breeding him. Because of this developmental window, the dog is able to fully mature physically and psychologically, creating an ideal setting for mating.

The mating season for dogs, also called "heat" or "estrus," typically happens twice a year, with each cycle lasting around 21 days.

Signs of receptivity to mating, such as increased sociability, restlessness, and an enlarged vulva, may be seen in female Formosan Mountain Dogs at this time. At the same time, male dogs may show an increased desire to mate, which is in line with their species' normal reproductive cycle.
