Thanks for all the thoughts. I know this is something with a 1+ year rehab time, if it ever heals... But 1 year is a long time. I don't know if I really have my head wrapped around that yet. Here's a little ray of sunshine. No blood or albumin in his stool. Ran the test tonight, both negative. He almost didn't poop for me, was putting his blankets on to go back out when I was finally able to snag some. I'll send the pictures of the results to the vet in the morning. With his stifle shaved, it makes applying Voltarin really easy, too.
