I am sure elderly or injured "dunb dogs" wouldn't care what they are seen in as long as they get out with their owners. All dogs I have seen have been very intelligent, maybe you are referring to the dumb cats that tear the strollers to bits.
A delivery driver drove passed my sons Nissian ute and his back door flew open damaging the taillights and side of the Ute. It was sorted out by insurance but it the inconvenience of it all as he still had to get to work.
