Australia has one of the largest percentages of 'Wastage' in the racing industry (potentially great horses that are no good for racing and therefore euthinased or sent to slaughter). Alot of young horses are broken through their training even before they get to the racetrack. I am currently working with a trainer who is employed to break in and train thoroughbreds to race as 2 year olds. He does not advocate this type of racing, and does not enjoy having these young horses ridden whilst they are still so underdeveloped. So my question is, what are the dangers in riding a 16month old horse?
