Train the dog to let you know when it has to go out. When it lets you
know, get up and let it out.
A doggie door is also a raccoon and other animal door, and has been used
by burglars to unlock doors.

I forgot about that one. A couple was arrested this week. They
had been using their 11 yr old to gain entrance to houses through
doggie doors for 5-6 years.

Google 'doggie door burglary' for some eye opening stories and videos.
