Found this book at a National Trust shop in the UK on summer holiday. Photos are clear, information is accurate though I wish a bit more detailed; the original audience - and acknowledged research helpers - were local children from farming backgrounds, who were able to add "professional" touches to the descriptions.
I brought this to a specialty dog show for herding breeds; the handlers, owners, and other spectators thought the book was brilliant! It was so popular, I had a hard time getting it back from all of its new fans.
