One thing I know about a LOT of spanish horses out here (we have a rather big stud farm round the corner, and round the other two corners three other yards that import).... PLEASE get legs x-rayed and take your farrier.
70% of spanish horses I know, whether imported from Spain or bred out here, have leg problems of one sort. More serious, one has ring bone, and the other has tiny tiny upright hooves that have put so much pressure on his joints the cap in his hock is broken- they're trying meds and rest but if it doesn't work..pts.
A lot of them I know dish- but that is something (apparently) they look for in Spanish horses, and a lot of leg issues from hoof position, how narrow, upright, flat etc they are.
Yes that is specifically why we drove 3 hours for this breeder is the horses are very well conformed and their movement tends to be less "wingy" than most Spanish horses. It is a really old line and they have broodmares/studs that are well into their 20s and sound.
I also have friends with Spanish horses - we are well aware of the breeds issues.
Looks like YouTube has a huge bug right now so I can't actually update or edit any of my videos right now :) So we will have to hang tight for videos!
