Just because trainers land touches does not mean they use prohibited substances.
Agreed – it doesn’t necessarily follow. What does raise my suspicion is when a trainer improves a horse from another yard out of all recognition in a very short space of time.
but could that not equally be down to a change of scenery or different training regime that is better suited to the horse?
That is why I qualified the statement with "in a very short space of time", Paul. Of course some horses are going to improve with a move to a better or more suitable yard. The cases that raise eyebrows involve horses who seem to improve dramatically in the space of days.
