Sadie has been limping pretty hard since we got back from Tahoe last week. We had her on Rimadyl, but I weaned her off that to see how bad it really was and she pretty much turned into a three legged dog. So we went to the vet this morning and she has blown out her right knee. Sadie had a Tibial Plateau Leveling Osteotomy in March 2008 at The Sams Clinic in Mill Valley. We're heading up there on October 8th for a consult. Surgery will be needed and at this point I'm guessing it will be the same procedure.
