computer is being a prat and not letting me download the ea dressage rulebook. can someone tell me what the rules are relating to age in competing an imported horse at young dressage horse competitions? i understand here that horses ages are as of august 1 that year? so are all imported horses competing essentially a year younger? eg a horse born in september 2008 will in 2012 be a 4 year old, a horse born in feb 2009 will also be a 4 year old in 2012?
