I've recently come across a website that I think could benefit many EF dog owners: http://careforreactivedogs.com
The program, developed by behaviorist Jennifter Titus, is aimed at owners who need to help their dogs with reactivity issues, but IMO all dog owners might benefit from reading through the site. There is a wealth of information here.
Many of the points discussed are what I would consider to be Training Fundamentals, the basis of pretty much all we do with our dogs. I wanted to highlight this site, though, because Ms Titus presents these fundamentals nicely bundled and in an easily accessible way.
The concept and exercises could be applied to all sorts of training goals.
For those of you with reactive dogs, the CARE protocol might be a valuable addition to your training tool box.
