Ovariohysterectomy (OHE, Spay): Once an animal is spayed, she is no longer able to become pregnant. If an animal is pregnant at the time a spay is performed, the pregnancy is terminated and the offspring will not be viable. By signing below, I am verifying that I understand that if my pet is found to be pregnant during surgery and I wish to proceed with surgery, the pregnancy will be terminated and the litter will not survive.
