My mom has decided to buy a four year old mini as a project for us, but I'm kind of at a loss as to where to start... First of all, he's only half castrated. I don't know why, maybe he had a retained testicle or complications, but we have to have him 're-gelded' as he's very studdy right now. I went to see him today and he was out in a big grass paddock, which wasn't really a problem- he came up to me, was a little shy, but sniffed around and let me pet him, we lured him into a stall at the back and from there just made friends, gave him some grain and managed to get a halter on him fairly easily, that isn't the problem. Once the halter was on we walked him a little bit, but he doesn't lead at all throws his head, bites at the lead, tries to bite your hand if you go to grab at the halter- his worst habit by far is that he'll rear up as if to strike out at you.
The guy whos property he's on right now says he'll calm down a bit once we get him fully 'snipped' but I'm definitely going to need some suggestions with the halter training. I'm an experienced rider, but I have little experience with mini's and am not quite sure how to get him to lead and how to break the striking habit.
