I believe the parents were OFA certified (I think that's the right thing). Champion father, mother was imported from Germany with good lines. I have lots of paperwork but I'm unsure of where they're at since we moved (probably boxed up somewhere). I emailed the breeder to let her know what was going on. I don't need her to do anything I just want her aware. I heard hydro therapy was also a good and safe way to build muscle. Consult with the actual surgeon is tomorrow 8:30 am to decide the path we'll take. Going to schedule surgery asap. 8 week recovery time for each knee which is really unfortunate as its almost summer
