When I owned a flight school / charter I used to take my sheltie with me in the twin , his name was Wilbur Wrong and he wore the four gold bars on his front legs as well as my airport security tag hanging off his collar, I pasted his picture over mine and re-laminated it.
Never had a problem with that set up as everyone just laughed at it.
Old Wilbur really looked the part of a pilot walking across the ramp all dressed up like a real pilot.
