Hi John,
Perhaps, I might be regarded as one of those hungry owners, but 15 years ago, when our horse, a 6 year old, was finding it hard in the top grade, we sent him to the US. Okay, we did not sell him, but kept in the ownership. These horses are bred to race, and if their racing life can be extended, with careful consideration, then it is a good situation for horse and owner. He performed creditably, but unfortunately died, when he had a heart attack.
The dream of getting a good horse is the optimum for us owners, and wishing everyone in ownership of this wonderful sport, the best of luck in those endeavours.
Cheers.
Robert.
