Sadie had her routine blood test on Saturday, to check on the health of her liver, which has been negatively affected from arthritis medication. She has been on Metacam along with Denosyl which was doing a good job of keeping her liver enzyme levels within the normal limits. Well, this last blood test showed her liver enzyme levels highly elevated, even though she has been on Denosyl. So, the vet recommended we try yet another arthritis med - Zubrin. Has anyone any experience with this? Also, does anyone have any experience with the problem she is having - all the arthritis meds negatively affecting the liver? It seems she does OK on them for so long & then starts to show problems. I'm getting worried that we are going to run out of arthritis meds that don't hurt her liver. She can't go med-free. She is obviously uncomfortable when she is off meds. It's very frustrating.
