I would like to register my mini, as a mini based on height. Is this possible? I do not know my gelding's sire, or dam. My mini is 34 inches at the last mane hair, and is a paint with one blue eye. I realize that a gelding does not need papers, as a non breeder, or for most shows. Also, is a DNA test available to show bloodlines? If so, is it expensive? My mini isn't fancy, but I love him! Every time I look at him I wonder about his heritage. Thanks!
