Do our pets know?!?!

So I decided to let my dog Sugar sleep in my bed with me tonight, but I got super horny so I decided to whip out my good ole vibrator and go to town... I thought, "Oh she's a dog, she doesn't know what the hell is going on". BUT just as I was about to begin, she got up and turned around! Also kinda buried herself into the covers.... uhh coincidence? Anyone have any similar stories??
