Nancy Franck of Cedar Rapids, Iowa, had been in the hospital for two weeks receiving treatment for cancer when she got an unexpected visitor: her dog, Sissy. But Sissy was not smuggled into Franck’s hospital room by her family. She had walked to Mercy Medical Center by herself.

The miniature Schnauzer apparently took it upon herself to walk the twenty blocks to the hospital, even though she had never been there before. The devoted pet was caught on video cameras in the hospital lobby, trying to figure out how to find her owner.

“She was on a mission that night to see her mom,” Dale Franck, who had been caring for Sissy while his wife was in the hospital, told ABC News, “but she couldn’t find the right elevator to take.”

Franck noticed Sissy was missing around 1:30 a.m. and was hunting for the dog until hospital security called him. “She found my number and house address from her tag on her collar,” he said. “I was so relieved, and I asked my daughter go and pick her up.”

Franck’s daughter went to fetch Sissy and was able to secure permission to bring the devoted dog up to see her mom in her hospital room.
