How do we keep 2 yr old from opening screen door?

Ha, shock collar. I've tried one and it hurt like hell, never put it back on my dog, a good swat and a sharp no worked way better anyway. your electric fence can't go with you and a adhd dog will wear out the batteries. Plus my dog listened till the day she died except for leaving a trash can out, never could break her of that, musta made her happy.
