My husband and I are foster parents for a local shih Tzu rescue group. My foster dog Cagney has this sixth sense of knowing when my pouch is full. He has this talent of jumping right on my pouch when I have just finished eaten. Oh it hurts. Can't get mad at the little guy he is too cute, but I am amazed at his talent.

You might be actually making a sound or your breathing changes when you are full and not even be aware of it yourself, but poochy can sense it right away.
