I would be gentle though, when telling on this vet. It's not her fault that she can't find out what is wrong. It isn't like they know every disease in their head. But I do second a second opinion. Does Logan have runny poops? I noticed the past couple days Delta had bad runny poos, (they've gone away now) and her water intake increased a lot. The freaking out without food and then not eating it is very confusing though.
