Get cans with a twist locking lid used to deter bears. Keep the lids on tight and keep the cans out of your dog’s sight it possible. Consider different sprays that are available at pet stores which will deter your dog from going near the cans. There’s  cayenne pepper and powders like bitter alum. Don’t depend on these sprays alone. It is very important that you make sure that your dog cannot get in your garbage at all.
