Thanks, Will, that was most helpful. I will follow the prevention protocol you write about. Our "traditional" vet is extremely conservative around vaccines for our hemangiosarcoma girl (she's survived 28 months now with an alternative therapy Penn has been studying, also recommended by our vet), so we aren't getting pressure from him. She does still get joy running a course or two, so I just want to be wise about supporting her health as best we can.
