Innocence

Have you ever wondered if animals are capable to lying? Are they capable of being devious and manipulative just for the sake of pride and selfishness? Right before bed time, I let Doggie out to pee. She always runs right back home because she knows she will be given a doggie treat. I know she checks back to see if I see her. She would squat and empty her little bladder. But, I wonder if she is devious enough to "pretend squat", making me think that she has done what is expected of her so she can get her treat.
