I'm going to put on my veterinary practitioner hat. I work and live with it every day.
I look at it from that perspective. I look at the sum total of my career, which has been a long one, and I look at what's important today, compared to almost 40 years ago when I graduated. When I graduated, there was no real thought about pain management in animals, whether companion animals or food animals. In fact, at that time, there were few or no licensed drugs to be used, especially in food animals. It was a very narrow selection.
As we've progressed, there are new issues that we become more attuned to. As professionals, we take actions to deal with them and contribute to improving the health and welfare of the animals we serve.
