Paintedpastures- thanks! I've done a ton of research. Most of the sources only have info about horses that had most of their training before going blind.
BarrelRacingArabian- The same lady owned a mare who was kicked in the eye and lost her sight in one eye. She was still a great kids horse and jumped and barrel raced. But having some sight is very different from having no sight.... and of course, this mare was broke before going blind
**Some horses come into our lives and quickly go~ others stay awhile, leave hoof prints on our hearts, and we are never ever the same.**
