Surveillance footage shows the dog arriving at the Cedar Rapids Mercy Medical Center in Iowa early on Saturday morning, and running around the halls - apparently in search of someone very special to her. Franck had been there for the past two weeks following chemotherapy for uterine cancer.

Its just like she knew exactly what she was doing! Francks daughter, Sarah Wood, said of determined little dog, who is one of two schnauzers that the family owns.

She was on a mission that night to see her mom, Francks husband, Dale, told ABC News, noting one big obstacle. She couldnt find the right elevator to take.

Dale was informed about the dogs whereabouts at 5:30 a.m. by a security officer who noticed a phone number on Sissys collar.

Wood scooped up the dog - who had never been to the hospital before - and brought her to Francks room, where she woke to the news of the dogs amazing escape.

I said, Sarah did you smuggle this dog in? Franck told CBS News from her hospital bed. She said, No, she brought herself in here, Mom.
