What does my dog know and how can I talk to him about it?

Rex knows how you are feeling, whether it’s happy, sad or angry and he probably picks up more meaning from your human conversations than you might think.
“Dogs read us quite well,” said Stanley Coren, a professor emeritus in University of B.C.’s faculty of psychology.
“They can detect stress signals. When our body posture is less erect we kind of fold like there’s a big hinge in the middle of our chest.”
