Spaying your female pet…

  • Definition: ovariohysterectomy – removal of both ovaries and the uterus.
  • When spayed before the first heat cycle, there is less than one-half of one percent chance of developing breast cancer.
  • When spayed after one heat cycle, there is an 8% chance of developing breast cancer.
  • When spayed after two heat cycles, the risk of developing breast cancer increases to 26%.
  • After four heat cycles, or 2½ years of age, spaying provides no breast cancer protective benefits.
  • Pets with diabetes or epilepsy should be spayed to prevent hormonal changes that may interfere with medications.
  • Spayed females cannot have babies and should not have any further heat cycles.
