ROFLOL just like the old joke!
You've got your very own black Lab tests there, Shelly! Now, if Ami's cats take an interest in you, you'll have a Cat scan goin' on too!
I have no doubt that dogs, and critters in general, are aware of what's goin' on. That something is going on.
I think it's a great experiment. If you have a dog, or other critter, test when they are paying more attention to you. I know that when I had my Astro, there were definately days where he would be more attentive to me than others. This has been the case with all the dogs I've ever had. Cats too.
