Cobb County, Ga., police have arrested two Harrison High School students in a so-called "doggie dooring" break-in at a Kennesaw home.

Police say the two stole laptops, iPods, cell phones and beer.

The practice of slipping into a home by squeezing through one of the small openings used by pets is so well-known in schools in the area that it's been nicknamed "doggie dooring."

Police are warning homeowners to keep their pet doors locked when they're away from home.

Cobb County homeowner Deanna Haddock says she has received e-mails warning her about doggie dooring. She says she has kept her pet door unlocked all day but now she may start locking it.
