Hi all,
Re-posting as I realized that I forgot to change the greeting.
Do any of you know of any books on/about guide dogs that you'd recommend?
Preferibly non-fiction; I know there are ones about the different schools but I
worry about current they are as things have likely changed. Just curious; look
forward to any recommendations that any of you can provide me!! Thanks Madison
