It depends on the owner. There are many people who have taken on ex-racehorses (some of whom were so useless they never even raced) who love them and pay for their treatment when they get sick or injured, even if they can never be ridden again. I think the main danger for racehorses is between retirement and final adoption. Often many new owners and dealers are involved in this process and not all necessarily have the horse’s best interest at heart.
