I haven’t read any of his books based on his repeated misinformation about Border Collies, especially working dogs and the working dog culture. The majority of the working Border Collie community has been up in arms about his books from the beginning. When confronted, he claims that the point of his writings is that he “doesn’t know much” about the dogs and thats supposed to be the charming point of it. Yet, he has set himself up as a dog behavior/culture expert and IMHO has more responsibility than he will acknowledge. I did read his interview on NPR about putting his dog down for aggression, and in my opinion he did the dog a great disservice, especially considering the dog was one of the key characters in a book that made him famous.
On that note, check out Variable Star by Robert Heinlein and Spider Robinson – that is, by Robinson based on an eight-page outline Heinlein apparently wrote during his “juveniles” period in the '50s. Robinson works to capture the style and spirit of a Heinlein juvenile and mostly succeeds, although the distinctive Robinson touches (such as psychological self-exploration and mentions of Zen Buddhism) are there too.
