I've owned many Pitbulls in my time, All were great dogs but I did'nt know much about my own dogs back ground. I've recently recieved a puppy from Louis Colby and i'm very glad that I did. Having the book shows me what kind of History my dog has. I knew alot about the breed before I got the book but not as much as I know now. The book goes into great detail of how the breed has come along in all these years. It also puts the debate of the Amstaff and the APBT being to different dogs to rest. This book does cover lots of dog fighting history,keep in mind that 100 years ago dog fighting was acceptable and a common practice. I only live about 15 minutes away from Louis and I have gone out to his house many of times, each time I go we talk about the "New" sporting of these great animals "Weight pulling". So please dont think that Louis only promotes dog fighting,he doesn'nt,he appreciates them as they are and he really enjoys going to the pull contests, he much like me will never deny the dogs history. If your a history buff like I am this book is a must have for your collection and who knows...you might find a decendant of your dog in his book.
