There are some excellent videos out there demonstrating essential skills for dog owners and trainers; from preventative training such as teaching your dog to enjoy having his collar grabbed, good timing and attitude in clicker training your dog fun tricks, and demonstrations of how to follow out procedures that your behaviourist has recommended for behavioural issues your dog is experiencing (although in this latter case you should check with your behaviourist first that the procedure demonstrated in the video is suitable for your dog – as they are all inviduals and what works for one dog may not be right for another!)
Here are some of my favorites.
