Taryn, Jean Donaldson goes in depth with her explanations and employs some psychological theories (yay, college up 'till now wasn't a total waste

) that Jan Fennel did not.
DL was more of an anecdotal, flowing; almost biography of her experience with dogs while CC is broken up into theories, lists, charts, etc. CC leans toward the academic side while DL consists of applied theories.
I’m a bit disappointed that DL is the one with the index and not CC; but if I had to choose between the two, I’d pick CC.
Both were great books but I enjoyed Jean Donaldson’s cynical approach

I’ve also heard many people disliking the book because of the pretentious style in which she writes.
Lastly, CC overall offered more information. Since the books were of comparable price, I’d have to say CC is more “bang for your buck”.
I hope my little review helped
