Barbie is a 2yo Stafford terrier that is 32 days into her pregnancy. Ultrasound revealed a 7cm irregular heterogeneous mass along with at least 6 live puppies. Should I recommend a splenectomy ? I include a second ultrasound 6 days later with some changes to the mass.(38 days of gestation) Should I continue to monitor?
