Telepathic Dogs?

Have you ever noticed that dogs seem to know exactly what you are thinking?
Smash knows when I am ready to head back home during a walk even before I pull the leash that direction.

Do dogs really know what you are thinking? Do they pick up on body language, smells or do they really read thoughts?

This book describes an experiment where dogs were monitored by cameras while their owners were away. The dogs went to the door to wait for them when their owners simply had an intention about coming home.

Amazing stuff.
