Whip a small claims suit on her for five k. I know it is not what you paid, but it is the most you can ask for with the least amount of cost and trouble. See if there is any way you can sue her for two different things for five k each. Heck if you can find three sue her three times for three different things. It will give the judge three different chances to punish her. You can't get punitive damages in small claims. just acutal cost/losses which must be documented. You could sue her for future lost earnings maybe, in addition to your lost foal purchase price.
