How odd! Although this is a very good book and one that I frequently recommend, this review is not about the book. The book is based on knowledge and experience...not on 'asking around'.
I can not find anywhere in the book where it describes Dalmatians as 'dominant'! Generalising and labelling any breed 'dominant' is lazy and incorrect. Science tells us dominance is not a breed trait! Dominant over what? Neither does it suggest that Jack Russell's need a 'firm hand'? What is a firm hand? A slap? No dog should be physically corrected. This book tries hard to speak about 'reward based' training. Treats and clicker training are frequently mentioned.
If I am wrong and your old fashioned notions are included in the book please let me know where and I will stop recommending it myself.
