Other trainers have been hyping this book to me for ages, and I get it! It’s good! It wasn’t groundbreaking for me (possibly because I’ve spent those ‘ages’ putting together every scrap of free info I could find). I think she’s more reliant on the Coppingers than is strictly wise or validated by research buuuuut otherwise: Great introductory book for owners, especially if your breed is 'unusual’ or 'difficult’.
