Does your dog or cat talk to you ?

My dog talks to me through body language as many pets are won't to do. When he sees me he looks at me directly in the eyes. What intrigues me is the that pets do this cautiously. I have learnt to read his body language. An expectant look means that he is hungry. Smiling eyes mean that he is up to some mischief. When he is hungry, he runs off and lies on the ground pensively. He also makes some whinig moans when he is impatient or hungry.
