This is a surgical procedure to neuter a female animal,in which the ovaries and entire uterus are removed through an opening created in the abdominal wall. Complications are very rare,and uneventful recovery is normally complete within 10 days. Spaying is a permanent form of birth control. It prevents the possibility of a serious disease of the womb,common in older bitches. Spaying cannot be reversed.
Some dominant bitches can become more aggressive.
