I had a big old appy, blind in one eye when he arrived.........it was sunken in and weeped but other than that did not afffect anything, then he went blind in the other eye.............but we still went everywhere trail riding etc......you just had to do a lot of voice commands and let him know where he was going and how high he had to climb.............but in the SHOW RING........he knew his footing was good and we did it all, barrels, poles, trail, doubles pleasure...........one eye, no eye..........they can still have a great life and give lots back........... :cowboyhound.gi
