Words fail me. She left a sleeping man with dementia alone, and the dogs “knew how to open the back door.”
I guess the dogs are smarter than Sarah, unfortunately.
That door opening skill isn't all that surprising. The first dog I owned as an adult, half black lab and half Irish Setter, taught himself how to open the door at the top of the stairs from my basement to the rest of my townhouse. It was really neat when I had my hands full and was climbing the stairs since I'd just tell him to open to door and he'd do it.
