Not much you can do after the fact. If you catch her in the act then you could make a loud noise. I seen an episode of "It's me or the dog" and the dog would raid the fridge. They put an alarm on the fridge as soon as the dog opened it the alarm went off. The dog ran into the other room and stopped raiding the fridge.
heck the times i do catch her i will clap real loud and tell her to get out of the kitchen, she is dense! but my baby!
