TPLO surgery? My male shepherd had TPLO. While the outcome was good I'll tell you that was 14 weeks of hell as you pretty much have to restrain the dog from everything except relieving themselves.
Also make sure the vet is qualified in TPLO. It's a complex surgery and I heard horror stories of 1st timers thinking they could do it.
Fell free to PM me if you have any other questions.
