Choosing the proper venue for selling is the most important decision a horse owner can make when deciding to enter a public auction.


Entering an auction in which your horse will be in the top 25% of the horses offered provides the best opportunity for a favorable outcome. It is a common practice among horse owners to choose the sale, enter the horse, and then acquire an agent. Actually, it is best to consult an agent prior to entering a sale to assure that your horse will be competitive in the chosen marketplace. All too many horses return to their owners unsold, along with very substantial bills. Getting it right the first time can save a lot of time, trouble, and money.
