What are other options to terminate pregnancy?
If you absolutely want to try and retain the breeding integrity of your dog or cat, surgical sterilization is not an option; however, medical intervention is still an option. Before any type of medical abortion is attempted, the first step is to be sure that your pet is actually pregnant. Your veterinarian can confirm a pregnancy via ultrasound about 15-30 days after breeding. Alternatively, radiographs can diagnose a pregnancy about 35-45 days after breeding. If your pet is in fact pregnant, then your veterinarian can discuss your medical options with you. There are several
