Adversarial relationships are rarely productive. I'm sorry the pup had to bear the brunt of such hubris.
I think, as Dr. Traverse stated above, it pays to set up your expectations early on. Firmly, but kindly, and watch for the response. If it's "shields up!" you know it's time to keep looking.
An approach I've had my clients use quite effectively over the years is (note: I end up being the "primary physican" most often for my clients) saying something like, "I'm presently happy with my homeopathic (or holistic, if that's the case) vet, but would you be willing to work with me in case I need emergency surgery or diagnostics done?"
Most, when approached like this, are happy to provide the services you ask for. Those who aren't, you'll know it's time to move on.
