Dr. Lynn Hillyer:

I can only speak from my experience. I have been a veterinary officer for 25 years and there was one in that time from which I had to walk away. It is not a question of going too far before you walk away. You know a horse that is going to be dangerous, difficult or intractable and you just do not do it. It is as simple as that. We see them on training yards and on race day. It is a difficult time for a trainer and the horse. Everything has to be just right pre-race. We are not going to go in and mess that up. We do not do that.
