This book is poorly written, inaccurate and misleading. I am not talking about the occasional, minor inaccuracy, but incessant and blatant fallacies page after page after page. At one point, the authors suggest that one might buy a GH puppy, train it and then take it to the track and race it! The reality is that dogs are raced by large kennels that have contractual agreements with tracks to operate there. Unlike in some foreign countries, individual Americans cannot operate a single dog or handful of dogs. No distinction is made between the AKC Greyhound (a show dog) and the NGA GH (the racer). The authors stated that GHs are usually a solid color. Yet if one merely looks at the photos of the dogs in the book, it would be easy to see that most dogs are a combination of colors, often brindled. At one point, the authors say that Salukis are the swiftest of the sighthounds -- if that were true, then there would be Saluki racing instead of GH racing. I have personally seen GHs and Salukis run side-by-side at lure coursing practice and there is no comparison. This is an awful book that seems to have been written entirely on rumor, heresay and supposition. Don't buy it. If you did buy it, burn it.
