I actually didn't make it through the last third of the book. While I enjoyed learning more about what goes into training a herding dog (and, let's face it, there just aren't that many books about herding dogs readily available), the author's way of writing was not only confusing but also oppressively dull, especially when accompanied by illustrations that seemed to be meant to be humorous and informative but always failed to be the former and often failed to be the latter as well.
I don't really feel like I learned much, except a little more about the terminology and the complexity of getting a good herding dog. I feel like the author knew what they were talking about, but they weren't very good at writing it down.
Basically, I was bored and confused and very disappointed because I really AM highly interested in not only dogs in general, but herding dogs specifically. I've slogged my way through a lot of dull, uninformative training books which were often trying to be cute or funny (it would appear that dog trainers have no sense of humor but are afraid their books will be boring if they don't make jokes. The jokes make it worse, not better).
It's probable that I will finish this book eventually, and may use it for reference as well, but it's not good reading material, even for someone who enjoys reading about dogs and dog training. I suppose it's a little much to demand that a training book be entertaining, but not confusing and minus the painful jabs at humor would be an improvement.
