Why should dog sterilization surgery be performed as early as possible?
Dogs generally reach sexual maturity at around 8 months after birth. Female dogs experience their first estrus at this time, and thereafter it occurs twice a year, which is known as the "heat period," the time when pregnancy is possible. On the other hand, after male dogs reach sexual maturity, in order to induce the arrival of the female dog's "heat period," they display a series of behaviors pursuing female dogs. For example, barking, going to places where there are female dogs, fighting with other male dogs over female dogs, and so on. In short, it is very difficult for them to settle down.
