The resident AND faculty vet both agree it's a ligament tear & requires immediate surgery (they wanted me to schedule the surgery for next week, if possible.) They also recommended the TPLO method, which will cost around $4,500. The vet also says it would be best for her to have the metal plate/screws removed after 3-4 months of recovery to avoid the risk of infection, due to her past history, which is an additional $1,500.
We're relaxing at home with my sweet baby girl and trying to figure out how we're going to make this work. Today's appointment cost $600 (a small fraction of what we've already spent). Please send prayers and good thoughts our way. We could use them.
