Many years ago I adopted a 3 year old blind min pin. He was blind from birth as best the vet could tell because of the severe damage to the optic nerve.
He was prone to anxiety when it stormed or there was fireworks until the last year or two of his life..but then again so are many sighted dogs.
I made simple adjustments to our lifestyle-don't move furniture, his bedding, water-food bowls as well as teaching him "up" to step up a curb-"down" well you get it. Diligent on looking on the ground while out walking for broken glass, burning cigs, poop etc. Things a sighted dog would avoid. In fact it wasn't until later in life when he developed cataracts that some people even knew he was blind. I was blessed to have him 13 years-BEST DOG EVER!!!
