Tibial Plateau Leveling Osteotomy (TPLO)

Our sweetheart Rotty blew her ACL and needs a ~$2600 knee surgery!! :( I feel SO bad for not being able to get it done right away... poor doggy. This TPLO procedure is supposed to be fantastic, but the longer she goes without it, the more likely she is to develop arthritis, or other hip/knee problems from compensating for the lame leg. The only mitigating factor is that she seems to be putting a lot of weight on it, so it must not hurt too too bad, maybe it's only partially ruptured. I've seen blogs that collect for a cause, maybe I can raise money for Sydney's TPLO?
