You are good grandparents and even better free babysitters, so just relax over there. These are not all about you. Just have a laugh -- and maybe stop watching so much "CSI" in front of my kids. Adolpha knows what "blood splatter" means.
This just goes to show it might not be a bad idea to give a standardized test to all new parents before they leave the hospital with their new babies. Seriously! You have to jump through more hoops to adopt a dog than you do to have a baby.
