Welcome to DTA!
Great advice above. Having had a dog (many years ago) who went blind at an early age, I can vouch for the fact that his nose went into overdrive. Use that nose almost as you would his eyes, just give him time to adjust to the new training (since he can't see what you're asking him to do, as he would in 'normal' clicker training). Let him target with his nose (meaning, yes targeting is done with the nose, but in some situations, you may only want him leading with his nose and you'll take that, or turning his head and basically pointing his nose, that type of thing - and click/treat), take your time and let him take his - I bet he does great!
If you have more and/or specific questions, please keep asking. More people will chime in, cuz there's nothing better than helping a physically challenged dog enjoy a full life, and helping you, help him, overcome his fears and frustrations.
Can I ask something tho - what kind of harness do you use, and what was her history with this harness, that she can 'run and set sail' with no eyesight? Just confused.
