I just finished reading "How to Raise A Puppy You Can Live With" 3rd Edition (published in 1999) by Clarice Rutherford & David H. Neil. There is a lot of good information in it, but it seemed a little biased towards dominance theory. Also, the use of the "scruff shake" doesn't sit right with me. The book says the scruff shake is the way to communicate a correction to a puppy like its mother might; its a way for us correct the puppy quickly since we can't snap at it. From p. 82 The book talks about ways to desensitize food/toy guarders for example, but in the same sentence tells you to scruff shake your pup if it growls at you! I'd think this would be rather counterproductive, as it wouldn't really teach your dog that humans coming near its valuables is good, and it might teach them to skip the warning (growl) and go straight for the bite. The book seems to contradict itself because on one hand it tells you to scruff shake your dog, and on the other hand it says that you are responsible for teaching your dog that hands are good, that people are good, etc. I guess overall the book is ok.
