Well, unfortunately I'm pretty certain she has at least a partial tear. I went ahead and did the cranial drawer test on both her knees again just now because I knew I wasn't going to be able to sleep tonight for thinking about it. Her left has a definite cranial drawer sign, and I know if even I can tell, then it has to be pretty significant. Of course I'm trying to wait until after her appointment tomorrow to know for sure, but it's impossible for me to not already be thinking about surgical vs conservative/alternative treatments. No matter what, we can work things out financially to do whatever is needed for her (we don't really need to eat, right?), and I should get a discount, so that never hurts. Previously, I would have gone straight for surgery, no second thoughts. I really appreciate yall sharing your experiences with Mateo and Angus (and thanks for the links). I've kept up with your threads on their progress, and it's given me a lot to think about. Of course I want to go with whatever will give her the quickest recovery time (and therefore the shortest period of restricted activity) and least chance of future arthritis, but there unfortunately doesn't seem to be a consensus on what will provide that. I could probably read journal articles all day every day for a week and still not come out with a good answer. I am going to have a LOT to think about, that's for sure. She's my baby, I can't stand seeing her in pain. We went into mastiff puppy ownership with Rhaegar knowing that orthopedic problems could definitely be a possibility, but instead it's my tiny little Mazey! They certainly surprise me every day. I will update tomorrow after her appointment.
