Regarding so many new horse owners, who bring home dangerous horses, I am bothered by some of the advice given. A new horse owner isn't going to know how to ride out a buck, or get a pushy horse out of their space, or correctly discipline their horse swiftly and correctly, but not harshly.
IMHO, too many people buy a horse without spending time and money taking lessons. A riding academy doesn't JUST teach how to sit a horse and cue for gaits, and, perhaps prepare you to show. You really learn that a well trained horse is not a spooky and constant danger. Then, when you shop, hopefully, you are looking for a horse just as well behaved as your favorite lesson horse. I know that my riding students who became horse owners were looking for their own "Ro Go Bar", who was my beginner horse for everybody, calm and a confidence builder.
I could simply call the new owner with a green and out of control horse some derogatory name implying "uneducated," but I won't.
Today we are very much used to buying products that work right. Cars and trucks, for instance, work brand new just like we expect them to do. So do dishwashers, computers, heating/AC systems, cell phones are ear buds. We have a mental list of the cost of buying satisfying products and these lists are subjective. I might spend a different $amount for my clothes than you do, but still be satisfied. I also sew, so I can FIX some problems that maybe you don't know how to fix. Same is with horses.
WITH HORSES prices today are subjective and do NOT indicate quality or training. You cannot expect a high price tag to buy you a horse that is both safe and adequately handled. People are so impressed with bloodlines that they will sell the get of a money-maker with 30 days of training at an enormous price tag. The market is open. People who really CAN train a horse like this will spend the money, but anybody with the money can buy them.
You cannot expect that a low price tag will buy you that well behaved horse whose owners no longer have the resources to keep the horse. Other people never finish training their horse and will sell for a high or even a very low price tag and the innocent new buyer cannot distinguish a good buy from a bad purchase.
I have window shopped many horses and seen good and comparable animals for sale from $800.00 - ~$15,000
PLEASE if you are new to horses DON'T use these prices as a guide!!!!
