I have given rimadyl to 3 or 4 or 5 dogs (maybe more) over the years for short term pain relief with excellent results
No side effects observed. However, one senior small breed (spinal degeneration) did have diarrhea after 3 good months on the medication, symptoms cleared up within a week of the med being stopped.
I have also given tramadol with okay results, no observed side effects.

All effective medications have potential side effects.
