Just thought I'd give an update. We contacted the producer of the sale. He turned out to be very disappointed and quite angry actually because they were looking to put on an honest sale and bring integrity back into the horse industry so did what they felt neccessary to ensure consignors brought in sound horses. So yes, they could have asked for vet checks, but due to the caliber of horses and consignors involved in this particular sale, it wouldn't be neccessary for a vet to point out something the seller already knew, it just boils down to honesty. I feel this is good advice, if more people who ended up with a lame horse contacted sale producers instead of saying 'oh well, buyer beware' perhaps more of the bad apples in the business would be exposed. If there was more integrity in the horse industry, people would be more confident when buying and prices and quality of horses would go up and everyone would come away from the sale satisfied.
