short update....

New x-rays still show fluid in lungs now spreading, although more diffuse than before, could be that it's breaking up, but the vet was not happy about it at all...all other organs look fine. Some other things regarding bloodwork they did not expect to see, don't want to get into it here.
He's going over the xrays & test results with the senior vet, & still waiting to hear about the fungal panels...We should be getting additional calls from them today with more info.

At this point, we are hoping it is fungal, it would explain the odd assortment of Sherms' symptoms.

I have called our old vet in Ohio to see if he is seeing any animals with similar symptoms showing up there. His receptionist said it sounds like one other dog they are seeing, but who knows. He's calling back later.
