no my vet said nothing about liver functions and rimadyl... i think that i should be in the market for a new vet...as he was also the one who told me to give her tylenol....specificly....i only gave her 4 rimadyl over 3 days....but he mentioned no side effects at all....sshheesh!!!! i am very frustrated with this man.... the deli dog....p.s. the good news is she is sound as a dollar now....i think that she pulled her flexor tendons when playing....but this is why i am holding off until i find a better vet
