What ALL of them???

Looks like they have got us a new mat for our doorway, I wonder if we are suppose to wipe ALL our paws or maybe just the front two then dash in, do you think they would notice? Its a good job that we are intelligent dogs and can read upside down!
I wonder if Molly the gorgeous collie has one of these mats, I'm sure she would like one, we best tell her to check out our blip!
