Ha! Tell me about it. I used to live next door to one that would sneak into my open-front garage (more like a carport) and steal my husband's leather work gloves. We lost several pair before we figured out where they were going. He'd also steal my Golden Retriever pup, and the two of them would wander great distances before we could get them home again.
Had smart Shnoodle named Nero who would watch the construction crew arriving at the house under construction next door, then sneak in and steal a lunch or two, sometimes a bag, sometimes a pal. That dog never met a stranger. The dog catcher would come into the neighborhood, just open the door to his truck and Nero would jump in and ride with him the rest of his day. The guy would call us and say ‘Nero’s in jail again. Come get him.’
