It can be a real problem when smart dogs learn to open the fridge and help themselves to the goodies inside. One of our boys, Winston, and his sister, Comet could open the fridge when we lived in Tickhill, and many’s the time they demolished the Sunday roast! Childproof locks were of limited value. The fridge was adjacent to a cupboard with a drawer above, so we took to opening the drawer a little way to prevent the fridge from opening, but the dynamic duo learned very quickly to shut the drawer! Our last resort was to put a tin inside the drawer to prevent it closing – that worked!
