My dressage trainer imports friesians and she usually does groung worrk and starts a bit of riding in the summer when they turn 3 and then turns them away over the winter and starts bringing them back in during spring, but in NL they all seem to be broken at 2YO seems a bit early to me.
I think don primero is still standing at stud but im not completley sure, if he is still at stud Equine AI should have more info on him if you email them. www.equineai.com
Im looking to put my mare to a oldengurg stallion this summer but i cant find an oldenburg stud book to register with in the uk, does anyone know anything that might help???
