Maddie the Chihuahua somehow kept getting out of her pen and her parents did not have a clue how she was doing it. They knew that she could not have done it on her own, but there was no one else in the house to blame. After a while they decided to set up a hidden camera and see what was happening. When they checked the recordings, they were in disbelief. They completely forgot about another four legged member of the family who became very attached to Maddie.
