traditionally spaying is major, invasive, and dangerous, surgery, but I would research what it entails nowadays. When my coach's dog was spayed she only had three stitches total, and from what elizabeth says, this technology may have been transferred over, at least at some clinics. If you do decide on spaying, try to find a clinic that does it that way because it should drastically reduce the time she's on the table, and the amount of healing time required.
