Query: 'THE BOOK OF ALL DOG BOOKS KNOWN TO MANKIND'

Well, I surely don't know exactly what to expect in this book just yet, but knowing I'm buying from Amazon.com, I feel very positive about this one, indeed. Being a dog owner and a dog lover, myself, I highly recommend this book added to anyone who's like me who lives to study them. I haven't yet received mine, but will hopefully soon get it through the mail eventually. Shop Amazon and you can save big!! :) This book will most surely contain more than enough dog breeds to boggle the mind, and that includes the rarest, not just the rare breeds, but the ones almost unknown to man that died out or are fixing to become extinct. I myself, own a rare breed, with only 50 purebred registered in Canada---a Canadian Eskimo Dog.
