Update
Run all the worming protocols through the dog. Zole/TMZ, Fenben/Pyrantel, etc.
No change.
I hit him with Dex for two days.
Been on predinsone since then, 4th day today.

He has mashed potatoes shit PILES now. Not the real runny pancake batter that just spread out all over. This isn't what we want, but man, it's an improvement.
When reading about the malabsorption problem, I noticed it said some blood at times. He has a little bit of blood in his stool ever now and then.

With the way he is responding and from what I see and read, I think this is what his problem is. I'm going to continue on with the prednisone as long as I get positive to more positive results.

I truly appreciate everyone's help on this situation. JACK - many thanks for simply mentioning this disorder and I doubt I would've found as quickly as I did here on this board. This is a class act board.

I'll keep dicking with this situation and I'll keep all you guys posted so we can all learn something - hopefully.
