Ok this has really got me thinking about several things... First of all, years ago when I was delivering newspapers, I had a customer who has a blind and deaf dog. He was really old, but was still able to move about the farm. They put signs at each end of their property warning drivers that there was a blind and deaf dog crossing. This helped drivers to slow down in case they saw the dog crossing the road. A few years later after the dog passed away, the signs were removed.
Second, we had a dog Stormy, who got kicked by a cow, ( we think) who was seizing , we took her to the vet, who didn't give us much hope as bad as she was. 2 days after she was injured, then vet called us,( we checked on her daily) and said to come and get her. Stormy, a Siberian Husky with a very unique voice, was driving the vet crazy. All she did was howl, she was thrilled when we went to pick her up. She was unable to move her hind legs at all, but was otherwise ok. Frosty, her sister, missed her terribly, and was also thrilled to have her back home. Frosty did not leave Stormy's side, ate with her and actually would push food to Stormy, so she would eat, and bring her toys to play with. When we were outside playing, Stormy would drag herself across the yard to be with us. So we would be sure to stay close to her. Within a week Stormy was up and moving around again, very wobbly, but using her hind legs. When Frosty had her pups, Stormy was the best "mother" I have ever seen. Those pups would climb all over her, and it would not bother her at all. Frosty would get tired of them and get up and leave. Stormy mad a complete recovery, except for slight tremors every once in a while.
Third and last... My aunt Marti, she was born blind, and how she can manage I have no idea. She is absolutely great. She lives by herself with her cats, but she has had guide dogs in the past. When I went to visit her one day, we were driving to the resturant, and she was talking to my sister and the girls. SHE was giving ME directions on how to get there. It was.... Ok you are coming up to such and such street, turn left onto whatever street, oh there is road construction there, oh you just missed that stop sign, ect. ect. I couldn't believe that she is blind. Nobody else noticed me missing the stop sign but she knew. You see she used to work for the transportation service and would give directions for buses and things. This was back in the 70's before computers and stuff. Marti has live all over the midwest and south, always on her own. The local paper did an interview on her one day and she made the comment that she was never made to fear her blindness. Dad helped her alot, one day he convinced her to climb a tree with him. She got up in the tree, and Dad refused to help her down. He climbed down by himself and made her do it too. Marti loves to tell stories about how onery Dad was as a kid. But because of the was she was raised she has never be badly affected by it.
These are just 3 wonderful examples of how you can help you animals to adapt to their limitations. (No, don't encourage your puppy to climb trees.) Sorry this is so long, but I wanted to let people know about all of this.
