There is no real benefit in removing the uterus of a young, healthy animal. Initially, it was believed to prevent problems later in life. However, many papers have since refuted this rationale. Malignant uterine cancer is very uncommon in dogs. By simply removing the ovaries, hormones that may cause uterine cancers and infections are eliminated. Laparoscopic procedures are considered minimally invasive because of the much smaller incisions that are made therefore helping decrease healing time, decrease pain, and less importantly smaller scars.
