I'd not heard of her before, but after reading the article, I think her book would be very interesting.

At our dog walk yesterday, I kept my dogs away frm the other dogs unless the dogs appraoched them. Not always the easiest with 3, but although I know mine are very friendly, I also know that many dogs do not like other dogs in their face, and espically three at a time, and espically on leash. I was amazed at the number of people that let their dogs wander up to other dogs, regardless of size or the other animals desire to get away.
