Spay vs. Hysterectomy in Pets: Key Differences and Health Benefits

Spay (ovariohysterectomy): Removes ovaries and uterus.

Hysterectomy: Removes uterus only; ovaries remain.

Why Spay Is Standard

• Eliminates ovarian cancer risk
• Eliminates uterine cancer/pyometra risk
• Prevents heat cycles and associated behaviors
• Reduces mammary tumor risk if done early

Hysterectomy alone is rarely performed in veterinary medicine; ovariectomy (ovaries only) is an alternative in some countries. Discuss with your veterinarian.
