Our younger son’s dog, Lil’ Man, has been living with us and has started accompanying me on my errands. He prefers the truck, because he gets to sit right next to me, with our heads are at the same level. And no, when I go into the store, I don’t have to even consider locking my truck, which I rarely do anyway.
But don’t tell anyone that he’s way too friendly, and would probably start wagging his tail if someone approached. Looks can be deceptive.
