OK, supposing you wind up with the pony, then what? Would you put it up for sale or keep it? If you sell him you have no idea of how his future will turn out. Are you going to pay the castration fees? Who's going to train him? No one wants an untrained pony for their kids. There is no substitute for many miles under saddle and who's going to do that? I suspect you're caught up on this idea of rescuing this pony but with no real plan in place.
You're assuming things about me, and it is slightly irritating. I am most certainly not a child. You did not say that, but it's implied in the tone of the post. HOWEVER!!!
I do see and completely understand where you're coming from. They're all valid questions, for which I have answers. The likelihood of me getting him and having him for myself (right now) seems very slim, I've accepted that. I have not been able to get a hold of my brother's girlfriend, but I'm trying. But IF I do, I'll keep him. For a little while, at least. A few years. I understand that selling is always a toss up, which is why when I'm selling animals, I always check out where they're going, and who they're going to. I know that's not always a guarantee, but it's better than just letting them go to the highest bidder. And I've got a fairly good idea as to who would want him, and would be able to continue to work with him. I've already got some money put aside for castration, and with the job I've got, it won't take long to finish getting it. I've got a barn with two large stalls and a run-in, and a 10+ acre pasture with a pond, plenty of area for him to run and graze, with shelter and fresh water (none of which he has now). I have experience training, and though I'm likely too tall for him, I've got a good friend who trains horses and ponies and is already very excited as she hasn't been able to work with an untrained horse in a couple years. I don't plan on starting anything under saddle for at least another year, as I want to work on his biting, possible kicking, and desensitizing. That's a huge part of the training, especially with a pony/horse that is likely to be used for children. I am not clueless, I understand the work it's going to take to get him to where he needs to be. I know it's going to take a great deal of time and effort, and a lot of patience, all of which I'm willing to give. I'm not jumping in to this thinking it's going to be easy or cheap. I'm not doing this on a whim. It is something I'm very serious and passionate about.
I understand and appreciate your concern, and I thank you for any advice you (and anyone else) are able to give. I'm open to any and all suggestions.
