I think individual patients have very different preferences on this. I've taken pets to a few different vets, and some say things like "There are many possible reasons for these symptoms. Let's try XYZ and see how it goes." Others are more like "Your dog has X. We'll do Y and it should clear up." My preference is for the one who I think is being honest with me about how certain they are about what's going on, and when a medical professional seems like they want to appear 100% certain all the time it makes me worry about their judgement. I think many people have the opposite preference, which seems to me is asking for dishonesty. Seems like an ethically tricky area.
