Please...please...please... keep throwing out anything that you think might help or questions we should ask.
It's everyone's input from this forum that has kept us questioning and looking for answers. I was about to the point of looking up the vet Eddie Walker mentioned and driving 2-hours as a last ditch. This last visit we really questioned his breathing and how this all started with Mason coughing or trying to clear his airway. It's now looking like maybe the vets had it backwards, thinking the breathing distress was a symptom of autoimmune, where it might be that the lung infection was actually the cause of the other symptoms. I say maybe, because fungal infections can be caused by weakened immune systems. But at least now we're looking at and trying something else, because obviously the first treatment wasn't working.
He's really, really thin. You can see the backbone the entire length of him and count every rib. My wife is trying everything she can to get him to eat something. I'll be home Friday and will try to find more innovative tricks to get him to eat.
It's interesting that he's developed some of the same "coping mechanisms" that my MIL had developed when she was suffering from COPD. Like my MIL, he has a shallow breath with an abrupt exhale, my MIL would often stand and bend over resting her elbows on the counter and raise her backbone, a position they call "tenting" to help facilitate breathing. Mason will often stand awkwardly, which we thought was him being dazed. I think he just stands there because it's easier for him to breath standing than laying down. Even when he lays down, it looks somewhat awkward, like he's stretching out his torso. My MIL would also limit how much she ate, because a full stomach would impede her diaphragm and make it difficult to breath.
Anyway, I'm somewhat relieved that we have another path to try that might have some promise.
Here's his xray. I think Ray Charles could read this one.
