What keeps vets awake at night

The thought of an animal suffering has always upset me. Growing up, we had pet cows, horses, sheep, goats, dogs and various other beasts, that for some reason required a home and found their way to us. I always thought of these creatures as my friends. The idea of pain or suffering befalling them was enough to bring me to tears. Before I had finished school, I had decided that I wanted to be a voice for the voiceless.
