Maybe not. It depends on how early you catch it, whether it is open or closed, and how sick she is. If the bitch is feeling relatively well and the cervix is open (draining discharge), then medical treatment can be effective. Medical treatment usually involves hospitalization with intravenous fluids, antibiotics, and treatments that aim to decrease progesterone and empty the uterus. Medical treatment costs more than spaying, but can preserve fertility. We have treated many bitches who have gone on to have successful litters.
