I think I remember someone mentioning this book before so if I've duplicated, I apologize. But....this book was soooooooo good and this dog sounded AMAZING. It's called A Big Little Life by Dean Koontz and is about Trixie, a Golden Retreiver Dean and his wife Gerda got about 10 years ago. She was 3 when they got her and was a retired service dog. (she had a joint issue that "forced" her into retirement) This isn't a Marley and Me type book...this dog was (in a good way) scary intelligent, dignified and, as described by DK, joyful. Ok yes...the ending is similar to Marley and Me BUT....it's well worth the read.
