It sure sounds like someone had a bad experience - but let me just say that you can get a bad horse or a misrepresented horse from ANYWHERE. And the more horses you sell, the more chance there is that someone will not get what they want.
Buyers have a responsibility too. You are not buying a motorcycle or a car or a blender that can come with a warantee. Buyers of living animals are taking some chances - and you have to do what you can to limit the chances for failure. If you are experienced at buying and selling horses, chances are, you would make good decisions with Chris White or any other horse dealer. If you don't know what you are doing, you should find someone who does and enlist their help.
Vet checks typically cost several hundred dollars - when you are buying a $1000 horse, that is not always a viable option. Hundreds and hundreds of horses are being sold for $1500 and under in WNY and PA. The market is poor and these animals are in need. So it is up to the buyer to make sure he or she is deciding wisely. I can recommend that you ask for an opportunity to speak to prior owners about the animal - often there is a record of his or her name/address. Or you can check with the vet on the coggins - that is likely who was treating the horse before. His or her address is on the document.
I did buy a horse once from Chris White and got exactly what I bargained for and I was not disappointed at all. I have not had occasion to deal with him again - but I might if he had a horse that interested me. But after buying and selling enough horses - I don't depend on the seller to tell me what I need to know in an objective way. If you read any horse ad on craigslist, you will see that these animals do everything perfectly and you would think they clean their own stalls! And all are to go to "good homes only" - or offer a discount to "a good home" - does that mean bad homes can have them for the full price????
My point is that as horse buyers, we must realize that we are taking an animal with a mind of his own and a spirit. It is not a piece of equipment. Horses also are herd animals - change the herd and it can change the horse. We know as buyers that people want, expect, and attest to an entire array of characteristics in a horse. A "calm horse" for a barrel racer is much different than a "calm horse" for a trail rider. But the ad can say "calm horse". So buyers need to take some responsibility, too.
Sellers should be honest. But there are varying perceptions about that. Just like the "calm horse" - some folks see an "easy keeper" as one you can basically ignore if you pasture him. Others think an "easy keeper" is a horse that only gets grained twice a day and has less than three supplements. Only you can say what an easy keeper is to you.
Training is similar topic - I like John Lyons - so I don't care if a horse can play the 7 Parelli games. I use a mounting block - so I don't care if the horse stands if you get on from the ground - will he stand at the block? I refuse to use tie downs and martingales and such so I don't care how well behaved the horse is if he is "gadgeted" - I want him well behaved on a loose rein.
So my solution, in short, is to go back to horsebuying 101 - Ask that the horse be out in the pasture when you arrive. Watch him caught, lead, groomed, tacked, and ridden. Then if you like what you see, take your turn. Ride him like you own him. Put him through his paces the way you would if he was at your place. If you don't know how to check teeth, feet, and the like, take someone who does. Lead him around and play with him. What you have on your lead rope is what you will have under saddle. Look at his stall if he has one. Put him in and watch for a few minutes for cribbing, weaving, etc. Watch him eat a bit of hay - you will see how he chews. Then watch him turned back out - see how he goes back to the herd.
If you are willing to work on training, you may want to attempt to teach a simple thing with the horse before leaving. Something that usually yields quick results. That will let you get a glimpse of how your training will go. If you want a fully, well trained horse - you will need to be more selective in this price range.
Horses, like people, have some issues. Just like some of us are overweight or have high blood pressure or a bum knee - horses will have minor maladies that make them require some level of understanding or special care. You just have to decide what kinds of things you can deal with. Then search accordingly.
I saw similar complaints about Butch Bockman of Lockport - now there is a shady character! At least Chris White is a rider. Butch adertised all his horses as "anybody can ride" and "kid safe" and then people complained that the horses were dangerous. No kidding! My solution to that - tell ol' Butch to put his butt on that horse and put him through its paces before you put your kid on! - He is a used car salesman for Heaven's Sake!
So before we linch Chris White - let's remember it is easier to blame others instead of ourselves. It is easy to ignore the "rules" - You should know how to buy a horse and if you don't READ and LEARN and TAKE HELP WITH YOU. And always, always remember - the horse that is not good for you will be someone else's perfect horse - they are not disposable. Lots of us find that horses are not a good match for us - but responsible buying and selling is important. And believe me when I say that private sellers can be just as problematic as dealers.
GET BACK TO BASICS - there are two parties in any sale and buyers have some responsibilities as well. We have all suspected that someone is not completely truthful when we are buying a car. Does that cause us to go nuts on the internet? No - we just walk away - sooner or later, those who are truly crooks will go out of business for lack of sales.
Merry Christmas and HUG YOUR HORSE.
