Schnauzer Byte: House Breaking with Bells On

If you are housetraining your Mini Schnauzer and don't have a pet door, check out these Dog Doorbells. Your Mini Schnauzer would ring the bells when they need to go potty, and you would simply let them out (or, if you don't have a fenced-in yard, grab the leash.)

Or the very crafty could probably make their own, since they seem to consist of sleigh bells and ribbon.
