Believe it or not, it wasn't very long ago that pain relievers for animals were discouraged. Even when I was in veterinary school 20 years ago, there were some faculty members who taught that relieving pain in our patients would encourage them to move too much and re-injure themselves. These professors weren't monsters; they were operating with the best intentions and teaching us the best medicine that they knew.
