“Spaying” is a procedure that involved surgically removing a female’s ovaries and uterus. It is done under general anesthesia, and requires minimal time spent in the hospital. Females are usually back home resting the same day of the procedure. Spayed female dogs or cats are much healthier than those who are allowed to breed. Spaying prevents uterine infection and reduces the risk of breast cancer. Breast cancer is fatal in up to 50% of female dogs, and 90% of female cats. Females who are spayed before their first heat have the most protection from these diseases.
