I had the same experience with liver failure and Rimadyl. I had a
Golden Retriever that had been diagnosed with arthritis and was put on Rimadyl. A few months later we had to put her down because of liver failure. I had no idea that liver failure was a side affect of Rimadyl when she was put on it nor was I told by my vet. I ran across an article on it after she was gone. I can't be absolutely sure that Rimadyl was the cause of her liver failure but I will always wonder.
