Short version: I have only had him a month and when I got him I had a chiropractor check him to find that he had his hip out (among other things). She came and saw him twice and cleared him to start riding. I have not actually managed to ride him yet ><
Anyway I was up tonight feeding my boys and noticed that he was holding his leg up and out to the side. I will organise for the chiropractor to come back out. But if anyone thinks something might cause this please let me know!!
Please ignore the other horse in the picture, he was doing this before I put him back in the paddock. I could actually take hold of his foot and hold it without him trying to pull it away. Which is unusual as he does not like having his feet picked up.
Also I graze here, so not all the horses are mine :P
