Jeri, I wish I had some magic words for your vet. My vet did not hesitate when I asked for a prescription for cypro. I'm using the liquid through Prescription Specialties. She did caution me about not knowing the quality but said that it was worth trying. She has also given me a Rx for Thyrol-L so I can get it through KV Vet. Maybe because I've been with her for 19 years it makes a difference. However, she knows that I will call her out even for routine things and not try to play "doctor" so she's not losing too much by giving me prescriptions for long term meds. Barbara
