Vet texted to say that unfortunately there isn't much we can do about his lameness but tweak his pain meds, and that he'll talk to me when I pick him up. So I'm going to try to finish up early and head over there to get him and catch up with the vet. Really not sure what could be going on. I just want to get him comfortable again. Poor bugger. 

So, the vet didn't have a great answer. We do know that, due to a bunch of rain, the back yard is pretty spongy, and we're thinking maybe he pulled something. He is supposed to have R&R this weekend, and we've done a good job ... until we had a loose dog wandering around in the back yard, and Mosby RAN over to it, ignoring me telling him to stop (which is super unusual for him). Ugh. Anyway, I'm supposed to text the vet Monday if he's not better, and we'll tweak his meds. I do trust this vet (he's the one who diagnosed Mosby after the first vet missed it ... he's also the only one that believed me that the Cipro was making him sick). He said there was nothing obviously wrong with his leg - no swelling, etc. - he just has limited range of motion kind of all through the leg, and he suspects soft tissue injury. It's so heartbreaking to see him limp around with only two good legs. We're hoping the back yard dries more today, plus we'll be mowing it (you have to wait two weeks to mow after you get sod) and that will help.

Anyway. He's also had diarrhea off and on, and is really shedding out his coat. He also has had an ear infection and we've got drops for that now. We are seriously considering taking him off the chlorambucil. If there were any studies that it really changed prognosis, we'd be more inclined to keep him on it. But I have seen a (slight) decline in quality of life, and I need to discuss this with his oncologist.

Sorry for the long post. I'm pretty worried about little Mos. And I'm NEVER saying anything about whether he's doing well again. I know, I know, it's silly, but I happen to be extremely superstitious and putting the "kibosh" on something is something I've always tried to avoid after years of training by my family.

Thanks for all the well wishes and kind thoughts. My heart is breaking for my pup right now. I hate to see him struggle.

Thanks. 🙂

He got worse over the weekend, so we took him to the ER last night. They took x-rays. Seems to be no metastatic lesions, but did find arthritis in his elbow and shoulder. They also suspect overuse. They added tramadol (which I'm not a big fan of as a pain killer, but if it helps take the edge off, ok) and gave us instructions to use a cold compress a couple of times a day. I'm staying home with him today to keep an eye on him. The tramadol has him pretty out, but since he hasn't really wanted to move, anyway, it's not that much of a change, I guess. Poor bugger. Fingers crossed he starts to improve soon.
