An ovary-sparing spay is only indicated in certain breeds that have been shown to have significantly increased rates of cancer after having their ovaries removed. These breeds include Golden Retrievers, Vizslas, and Rottweilers. A bitch that has an ovary-sparing spay must be kept away from intact males as she will still cycle (though she may not bleed) and will therefore be attractive to intact males. If she is accidentally bred, she could get a sperm-induced peritonitis, which would be a serious complication and require emergency treatment and surgery.
