divebuddy -I've had horses all my life including a few in racing yards. Believe me I'm anything but 'emotional' when it comes to shooting horses and have had to make that decision for a couple we have owned and its not easy. I was merely making the point that sometimes ,especially when mega bucks are involved, vets can be 'encouraged' to sign the euthanasia form . As for the value of older horses - an older dressage horse 12-18 years old can fetch more than a young 5 year old -you are paying for years and years of training and competing -they are not cars! they do not devalue with age!!
