Ah, I also have a 10 year old german shepherd. She is also very interested in the garbage...And the fridge...and the cupboards...and the doors...Let's just say my dog is Miss Houdini the mischief maker.

All I can say, is put the garbage and products behind a secure door.

Because of the problems with my dog knowing how to open doors, there must be a lock on every one. It's annoying, but atleast there will be no more joy rides through the neighborhood.
