.. after a million xrays.. I have to decide.. do I want a horse that needs adequan for one stifle and cortizone for her hocks and whatever acid for her other stifle?..... how about a bank account that someone else fills up when I need to do all this? and you know.. I was paying attention.. but I was so stressed out that I really can't tell you what the vet actually said was wrong with anything.. except that she needs a bunch of injections.. to make her perform better.. oh.. and trailers on her back shoes to help bring her hind legs back instead of just under... GAH! I love my pony.. why can't she be perfect?
That's the trouble with having horses vetted, you get all the gory details but no crystal ball to see how they're actually going to play out.
Your pictures look like she's using herself pretty darn well and the two of you look like you're having fun. If I were you I'd have a hard time giving her up.
Maybe your vet would be willing to discuss the x-ray results with you again. Often they end up saying things like it may cause x problem in a few years or never cause a problem, but it had to be mentioned because it's there.
