Ok I don't have a blind dog but i do have a blind cat.
Some things i have learned.....put different rugs down for different things. Like a flat rug for eating place. A Berber at the door to go out. Also different scents for different rooms.
This has nothing to do with the dog but just a FYI....we had built a set of stairs she she can climb up different things. She uses them constantly.
I also have a deaf cat. Really no big deal there either other then not to startle the poor thing. We tap the floor with our feet to call her.
We were actually told we were cruel to keep them alive. Can you believe that? Sunny has been Blind since birth and Brandy same thing. They are normal in ever way and are a great addition to our family. Sunny is 8 yrs old and Brandy 7.
