I would much rather see an echo performed by an actual cardiologist than a "practitioner" or "specialist", and will happily pay more for it.

I pay less than $200 at health clinics to have my dogs tested by Cardiologist via echo w/color doppler. It's not exclusive to find a clinic as other breed clubs offer them as well.

Sincere thanks for your input. It has helped with the decision as to which to hire for the health clinic.
