I had a black & tan Dachshund who lived in constant fear of the Rapture. He would gaze skyward nervously whenever outdoors, checking for large raptors. One night when he was very elderly he went out and never came back...just vanished into thin air. Several days of searching yielded nothing, and I'm never seen him since, so for all I know he may be cavorting at this very moment in the Elysian Fields, being fed chocolates and fresh sausages by doting admirers. I hope so. He was, after all, a very nice dog...although he worried way too much about things. His little velvety brow was always furrowed with care.
