Please do it if you can ,but 1st find one in your area and talk with the owner. You need to know how hard it is. I had a blind dog she had an infection in her eyes before they opened. It was a litter I raised , Pandy was an awesome dog but it took so much more time and the training was really different and you had to have a lot of patience. Once we got it togeather she was very eager to please. She was one of the best dogs I ever had. You will bond more than with a "normal" dog just becouse they become very dependant on you. You become the ears they need.
I wish you luck if your family does this wonderful deed, becouse it does become a family project as they need to learn the signals and commands too.
Not to honk my horn but I did get one leg to Pandys tracking title. Before we had to put her down (Her mother mauled so badly that she had to be put to sleep) (mom too she was too aggressive for a springer always picking fights) Pandy was 4 and they were the most fun I had training a dog.
