Timmy's story is really simple. His owner was hesitant as to his leash walking skills, and encouraged me to turn around if he resisted the walk. I agreed that I would turn back if I needed to, and I started walking.

Timmy needed someone who wouldn't buy his "I don't want to walk" story, and so I merely expected that he would follow me, end of discussion. And he did! Expectation is a huge part of working with dogs, because they read our energy. 

So, in brief conclusion, expect that your dog will do what you want them to do. You may need to work through a brief burst of resistance, but remember that they can't think as long term as you can, therefore you know what is better for them in the long haul.
