There is nothing comprehensive about this guide. I think it was compiled (because I can't bring myself to say written about the snake oil that is the text) by some guy cutting and pasting in a basement in Middle America. Anyway, there is nothing unique to Border Terriers in this book, just general dog info with some Border Terrier pictures thrown in. So for anyone looking for a Breed Specific book I don't recommend this series. In fact, I am going to put the think in the thrift store pile now.
