I'm sorry about not updating in so long. I had nothing new to report for a while there, but unfortunately now I do. He started on Levemir insulin a while back which is keeping his sugars contained very well, in fact he's now on a lower dose than he started on. Hopefullly he will soon be off insulin altogether. That's the good news. Now for the bad. His limp came back and got worse over time. After several visits to the vet and a 2nd opinion and 3 different pain medications, none of which helped one bit, my vet did xrays. It looks like it may be cancer in his left knee. So Tuesday he's going in for a needle aspiration bone biopsy and a chest xray to see if there are any lesions there. Bone cancers metastasize to the lungs first.
