ashtray cover

i found a white dog hair, nearly 3 inches long exactly, sitting in my ashtray. we don’t own a dog, we havent had anyone over in weeks, my ashtray is normally covered by a spherical candle so it couldnt have floated in unless it was uncovered (ie i was smoking), and the only dog that lives nearby is a shorthair chihuahua. what the hell. what the hell
