This book has been the greatest asset as I recently adopted a 4.5 year old poodle who is completely blind. Like many faced with blindness in a dog, whether a pet that previously had sight or adopting a blind pet, it can be scary and you worry about the dog having good quality of life.
Levin's book takes care of you, the pet parent, as you learn to deal with your pet's blindness, and gives a ton of tips and ideas to help the pup adjust. Dogs are incredibly resilient and with some guidance from you (as well as a happy mindset that the dog picks up on), they can have fantastic quality of life. My dog is one of the happiest creatures I have ever met. She is also a fantastic watchdog because her hearing is so keen.
I randomly found this book at a used book sale the day I decided to meet this cute little pup. I read most of it before bringing her home, so when she got home, I knew what to do to help her adjust to her new home. I taught her a "swerve word" to let her know that she was about to run into something and a phrase to realign on the sidewalk if she was walking on one side and headed towards some overgrown bushes. She has learned to trust me that I will tell her if she is about to run into something and will keep her safe. She feels so safe, in fact, that we have started running together (she started taking off during walks). After a few hours at the new house, she was running around it without issue and rarely bumps into anything.
I am now working on helping her walk down stairs and learn to play with toys (she was a puppy mill breeder and currently has no concept of toys). This book has so many great ideas for each challenge.
If your vet has told you that your pup is losing their sight or you are considering adding a blind dog to your family, this book is a must-own resource. Also, as an aside, blind dogs are amazing. They are able to be happy, healthy, vibrant, fun and productive members of the family. Their sight is their 3rd most important sense, behind scent and hearing, and they will adjust perfectly fine.
