Noel was once prescribed Metacam, however it was stopped when her meds had to be changed (Metacam isn't necessarily good for the organs). However, while she was on it, I did see improvement in her grip.

She's currently getting black cherry juice, which is supposedly good for arthritis, but I can't say I've noticed a difference like that which was seen with Metacam. I have noticed other benefits of using the black cherry juice, however!
