The document provides information about registering stallions in the International Dressage Society (IDS) studbook. To be accepted, stallions must be trained in dressage and be purebred. Registering a stallion in the IDS studbook costs $7,000 and the stallion's information will be advertised regularly for free on the IDS page. The registration form requests information about the stallion like name, breed, pedigree, color, height, and whether it is available for breeding along with any applicable fees.
