Query: Dissappointed

I was incredibly disappointed with this book, having heard it hyped on ever deaf dog website or literature I came across. I have owned a deaf dog for four years. This book was not helpful or useful to me at all. I would imagine that someone who is considering adopting a deaf dog, or someone who has just adopted a deaf dog would find it helpful. The book was published in 1997, the same year I adopted my deaf dog. I never encountered the problems the author discussed, and a great deal has changed in the deaf dog owner community in the past four years. Basically, if you have already gotten past the basics with your deaf dog... pass this book up!
