I'm glad that you were able to get it diagnosed early and can take control of it now. Hot Rod is recuperatiing from surgery right now for a grade 3 lp. His condition worsened very quickly and we did not suspect anything like lp. He was at a grade 1 at his annual checkup. His ligament was on the side of his knee and the surgeon deepened the groove. He's in week 3 of recovery and each day he is improving.
Good luck with Bella, we will keep her in our thoughts and prayers that she take to the alternative therapy.
