Hi there! Well...........Truman my rescue is pretty much blind too and does GREAT! He loves to go on walks and will follow behind me all over the house. Yes he has run into the fence and even walked off the back stairs before but now that he has been here for a while he has even started to go up and down the stairs.

Once they adjust to their new environment it does get much better. Truman will follow my voice all over the yard and house. I also do a lot of clapping and he responds to that really well too. On the leash he is wonderful! We had him on the trials for a walk last weekend and he was so happy that he was prancing....wouldn't have even know he was not able to see. I hope that you get a good prognosis from the eye surgeon. Good luck!
