Neutering female dogs is less likely to get sick, and it will also extend their lifespan and reduce the number of stray dogs. However, neutering female dogs has certain risks. Some dogs may be allergic to anesthetics, and postoperative care is more troublesome. If the female dog is not sterilized, it is easy to get uterine cysts, ovarian cysts, breast tumors and other diseases, and she will also have menstrual pain during estrus. Therefore, if the female dog is healthy and has a physical examination before surgery and good care after surgery, it is better to neuter.
