Hi all I have been reading lots of dog training articles and books. I have been very impressed with Jane Ardern's Mission Control: How to Train the High-Drive Dog, First Stone Publishing, UK, 2020. Ardern devotes a lot of attention to building steadiness and frustration tolerance. She takes emotions seriously, using Panksepp's paradigm. So, it is not just a book on behaviourism. Many new exercises, at least to me, are explained, such as mousey mousey.
