Oops, I should have updated this last week. A few days after Casper started the anti-inflammation medicine his leg was looking a million times better. The day of his surgery his leg was looking so much better that his surgery was canceled and we were instructed to keep him on the meds another week and then come back for a re-check. We had the re-check today and the vet was very pleased with the improvements in Casper's leg. She took him off the meds and wants to see him next week for another re-check after he's been off the meds. Yay! No surgery!
