After much pressure, I have finally managed to get a referral for Darcy from my vet to a well known vet cardiologist in Dublin. Darcy is 6 and the vet felt her murmur was mild, perhaps a grade 2 but suggested she start on meds. I then requested a cardiologist referral as I didn't want to start meds without a proper assessment. I have not visited a vet cardiologist before so any tips or advice would be welcome on what sort of questions I need to ask, things I need to know etc.
