My Zada didn't limp or show any signs of the knee cap slipping, but she had a grade 3 in both knees and had surgery on both at the same time. Did the Vet. tell you what grade she has? My Azrael has a grade 2 in both knees and it hasn't changed since I got her 3 years ago and it may never require surgery, but a grade 3 does. |
