Our new baby, Bridget, a three year old pitbull mix whom the kids affectionately refer to as Pigbat (due to her insanely large and batty ears and her piggy snorting) is usually at my heels in the kitchen. I didn't realize that she hadn't followed me.
In reality, I came back from the kitchen to find The Kid spit cleaning Pigbat's head to erase the evidence. And, really she only had enough time to sneak in two purple lines on her forehead which blended with her muted brindle coat. I don't doubt for a minute that if given a little more time to herself, she would have 'tatooed' Pigbat's entire body. The Rule of Markers is Never Walk Away from a Kid with Markers.
