I have three dogs and the oldest one(non GSD) is the only one that will go into the garbage. I use small plastic bags that hang on the upper cabinets or on the back door in the kitchen. I take them out every night and if I forget I have a mess(if they are on the door). She is 8 years old today, I got her when she was about 10 months, so I haven't had a garbage can for 7 years.
