Several solutions spring to mind. You might try a small container that fits inside an undercounter cabinet with latching doors. If your dogs are small, a freestanding trash can with a locking lid might answer your needs. A third alternative would have you remove any appetizing waste to a storage receptacle at an inaccessible (to the dogs) location (garage, breezeway, alley, compactor, incinerator). If your large dogs are getting into outdoor garbage cans, you can thwart them by fastening bungie cords across the lid from handle to handle on the can. Good luck! Hope this helps.
