Hi Marci, so glad to see you back here. Hope you don't leave us again.
If you remember, Zada had surgery on both knees at the same time. Long recovery, then that Vet. retired and moved to another state and she started limping again so I took her to the orthopedic Dr. and he found that the Vet. did not deepen the groove, so she had another operation on one knee.
I hope all goes well for my little niece. Let me know if you have any questions.
