I had to laugh at this report from Britain.
A talented mule has been blocked from competing in high level British dressage competitions, amid outrage from horse riders.
Christie Mclean, 30, from Stroud, Gloucestershire, had hoped to ride Wallace The Great, an 11-year-old rescue mule, in competitions with her dressage team.
But he has been barred by British Dressage because high level competitions are only open to horses and ponies - a rule branded "equine racism" by Christie.
Wallace, who only took up dressage at a low level last month, has been doing well in local competitions, placing third in his last attempt.
Like horses and ponies he has to perform circles, loops, semi-circles and straight lines in both walk and trot.
"He enjoys his dressage," said Christie, "He’s a happy little chap."
. . .
A British Dressage spokesman said: "We don’t have anything against mules or donkeys, but our rule book is quite specific. It refers to horses and ponies.
"It could be time to change the rules. Wallace may be the one to do just that. It’s not beyond the realms of possibility. But currently, sorry Wallace, beautiful and lovely as you are, it’s a no."
There's more at the link.
One wonders whether the reason for that rule is that owners who've spent hundreds or thousands of pounds on a prize-winning dressage horse don't want to see their pride and joy beaten by, as well as like, a rented mule?
