Little 80 page book which I enjoyed. Short books give you that easy accomplishment, and when you are recording your books on Goodreads, another notch in your collection.
I love reading of this author's work on his herding dogs, so enjoyed this book for that. I don't think there is any new ground here on working with herding dogs and sheep that he doesn't cover in his other books in much more detail. More, even just a little more, of what I like to read makes it work for me.
He undercuts his overall story on herding with dogs with at least two other things, one is the evolution of dogs, and the other is his disagreements with AKC. Although I haven't read it yet, his other book The Dog Wars: How The Border Collie Battled The American Kennel Club, is where he fully takes on that topic and I am looking forward to reading it. Both topics I didn't think helped this book that much, he could have put in more details just on herding sheep with dogs and I think it would have been better.
So overall, a good little book to pick up and read, but invest your money on his other books.
