My old Beagle was a mastermind and my husky x was the muscle. Beagle could smell food items like a shark smells blood in the water. You could see his mind working out how to get to the prize. We'd always put the food high up or pushed to the back of the counter. The husky was tall enough to steal muffins and cookies for the Beagle. I'd come home and find the plate on the floor, the muffins gone (except for the paper liners) and the two dogs looking smug.
Beagle also learned how to move the chairs away from the table and use them to jump up to the top. We caught him once on the table still engaged in eating a bag of Christmas candy.
The Beagle was a terrible thief...wallets, keys, books....my father's false teeth...your drink (whiskey & gingerale)...underwear...coffee (hence his name: Coffee) you name it, if he couldn't drink or eat it he'd take it down to his nest in a old armchair in the basement and thoroughly slobber it.
Saddest thing: when we were all out and working and he was alone all day he became quite sad. I came home early once and he didn't meet me at the door, he was on the couch in the living room, just saddly gazing at me, and lined up on the floor in a straight line was an item from each of our bedrooms. I broke down crying. Poor old fellow,, he was lonely and crying out to us. We changed our schedules after that and he had company for lunch every day. Best dog ever.
