Jenni, thanks so much for all this additional info! There’s never a need to apologize for a lengthy post — the more you can tell us, the better ;-).

I have to say that all of your concerns sound perfectly reasonable to me. It’s true that Cushing’s is thought to increase a vulnerability to blood clots, but putting an animal who’s recovering from a GI bleed on a blood thinner is definitely a head scratcher for me, too. In our experience here, blood thinners are not routinely prescribed for Cushpups, and I definitely agree with you that it seems like a very odd choice in Eli’s situation. I also understand your questioning of the high blood pressure. I believe I, too, would want to have more than one elevated reading taken during a high-stress situation to confirm the finding before starting on medication. So after encouraging you to rely on a specialist, I’m coming away with some of the same questions as you.

As far as the LDDS vs. the ACTH, it seems to me as though the majority of experienced clinicians actually prefer the LDDS as their leading diagnostic, but with the following caveat. Both tests are vulnerable to “false positives” if a dog is suffering from an illness or physical stress other than Cushing’s. However, the LDDS is more likely to be skewed in this manner than is the ACTH. So if a dog has other known physical ailments, the ACTH may indeed be the more reliable test. The trade-off is that the ACTH is more likely to miss diagnosing Cushing’s (“false negatives”) in a dog who truly suffers from it. So in my own mind, which of the two tests is “better” really depends upon the situation that is specific to each individual dog. Now knowing that Eli was suffering from these other underlying issues, the ACTH might indeed have been a more reliable diagnostic option for him. But given his overall symptom profile, I personally don’t doubt that he truly has Cushing’s.

So what to do now... I agree that it’s far less than ideal to have to speak to a different vet whenever you have questions. In a non-emergency situation, it seems as though you ought to be able to arrange to consistently talk with a single specialist who’s in charge of Eli’s care. If this practice can’t make that happen, then perhaps a different group would be a better option. However, if logistics are such that you’d rather stay with them, I’d encourage you to press them on scheduling a time that you know you’ll be able to speak to the vet you prefer. And then I’d proceed with explicitly asking whether it wasn’t risky to prescribe a blood thinner while Eli was recovering from a GI bleed. And I’d also advocate for a few additional blood pressure readings in less stressful conditions, too. If the answers you get don’t satisfy you, then I’m afraid I’d encourage you to investigate other vet options :-((((. Sheesh!
