Call it coincidence or love, but a miniature Schnauzer in Cedar Rapids, Iowa, ended up at the hospital where her owner is battling cancer -- even though the dog was originally 20 blocks away at home. 
 
 A surveillance camera in the hospital lobby caught the dog entering through the automatic doors and wandering around. 
 
 The dog, named Sissy, belongs to Nancy Franck, 64, who has been at Mercy Medical Center for about two weeks following surgery. Her husband, Dale Franck, 66, had been taking care of Sissy and her brother Barney, also a miniature Schnauzer, back home. 
 
 “She was on a mission that night to see her mom," Dale Franck told ABC News today, "but she couldn't find the right elevator to take."

 He said he noticed Sissy was missing around 1:30 a.m. this past Saturday, and he was worried sick. 
 
 "I kept checking everywhere, calling out, 'Sissy! Sissy!'" he recalled. "I was pulling my hair out." 
 
 He finally got a call at 5:30 a.m. from security officer Samantha Conrad at the hospital, saying she had found his dog, he said. 
 
 "She found my number and house address from her tag on her collar," Dale Franck said. "I was so relieved, and I asked my daughter go and pick her up." 
 
 The security officer and the hospital did not immediately respond to ABC News' calls for comment. 
 
 Dale Franck's daughter got permission to take Sissy up to Nancy Franck for a few minutes, he said. 
 
 "She told her mom, 'I got a surprise for you!'" Dale Franck said. "My wife was like, 'How'd you get her in here? Did you sneak her under your coat?" 
 
 His daughter said that the "little spoiled brat" ran away from home because she wanted to see her mom, Dale Franck said, though it's unclear how the dog actually got there. 
 
 "Nancy and Sissy were able to love each other for a few minutes, and then she went back with me," Dale Franck said. "She's my baby, and though it sounds funny now, it wasn't funny when she was missing. I was worried sick. I'm glad she's OK."

 He has one theory about how Sissy might have gotten 20 blocks to his wife. 
 
 "The only thing I could think of was that Sissy used to ride with me to pick up my wife from work next door to the hospital," Dale Franck said. "But we've never walked that route before." 
 
 Nancy Franck has been battling uterine cancer, and though doctors believe most of the cancer is gone, she is undergoing chemotherapy to make sure, Dale Franck said. 
 
 "She has a close relationship with Sissy," he added. "Sissy's 11 now, and we bought her when she was just about 8 weeks old. She came up to me, scratched my leg and fell asleep on my shoulder. I'd say we didn't pick her, she picked us."

 If you ever doubted the connection between a dog and their human companion, you might want to think again: For the Francks and their daughter Sarah Wood, it was something they can't really explain. 
 
 
 
 Sissy, a 10-year old Miniature Schnauzer, walked nearly 20 blocks straight through Mercy Medical Center's 10th Street entrance doors and right into the hospital lobby. 
 
 
 
 "I said, 'Did you sneak this dog in?' Sarah said, 'No, (Sissy) snuck herself in,'" said Nancy Franck. "Set the door off - she got in by herself too. So she was on a mission." 
 
 
 
 Sissy was apparently on a mission to find Franck, who is recovering at Mercy due to complications of a cancer-related surgery. 
 
 
 
 "A big boost -- it helped a lot, just to see her and talk to her," said Franck. 
 
 
 
 Before being reunited, Franck's husband Dale thought the worst. 
 
 
 
 Early Saturday morning, while Nancy Franck was still in the hospital, Dale Franck realized the furnace in their home was not working. 
 
 
 
 So he took Sissy and her brother, Barney, out to use the bathroom at around 1:30 a.m. Wednesday. 
 
 
 
 "I thought they both came back in the house," said Dale Franck. " I was panicking. (Sissy's) my baby. I'm sorry." 
 
 
 
 However, Sissy was nowhere to be found. 
 
 
 
 Dale Franck looked all over the house and outside trying to find her. He eventually called the animal shelter and Cedar Rapids Police before calling Wood. 
 
 
 
 "Dad's playing another joke," Wood said she thought. 
 
 
 
 About four hours later, Wood learned it was not a joke. 
 
 
 
 "Then I get a call from Mercy (Medical Center) security," said Dale Franck. "They say, 'We have a little dog here.'" 
 
 
 
 Sure enough, it was Sissy. 
 
 
 
 Wood went to the hospital security office to pick up Sissy, and says she was waiting in the office looking out the window when Sissy turned around and gave Wood a clear look. 
 
 
 
 "''Bout time you showed up, I've been here for a while now,'" Wood said, mimicking Sissy. "'Let's go see Mom, then you can take me home.'" 
 
 
 
 Security cameras in the hospital caught Sissy roaming the 10th Street entrance of Mercy Hospital, prancing around the hospital hallways, looking for Nancy Franck. 
 
 
 
 "I didn't think they could do it," Nancy Franck said. "I thought dogs could find their way home, but this one found the hospital." 
 
 
 
 The Francks say Sissy has never run away from home, and couldn't have any idea that Nancy was at Mercy -- or even where Mercy was. 
 
 
 
 The security officer let Wood take Sissy up to Franck's room to spend a few minutes with her. 
 
 
 
 "She was on a mission," said Wood. "The way she walked into the hospital, she was on a mission - she was determined to do something and she was going to do it. 
 
 
 
 "I'm sure when Sissy got home she told Barney, ‘Guess who I got to see, and what I got to do and where I went?'” Wood added. 
 
 
 
 Nancy is hoping to be released from Mercy soon, so she can spoil Sissy even more. 
 
 
 
 "It's amazing, and it's God's wish that we got her back," said Dale Franck. "What else can you say?" 
 

– Dale Franck was worried sick. Around 1:30am Saturday, he noticed one of his and his wife's two miniature schnauzers had vanished from outside their Cedar Rapids, Iowa, home. "I kept checking everywhere, calling out, 'Sissy! Sissy!'" he tells ABC News. Hours later, he got a phone call. Sissy, 11, had been spotted on security cameras entering Mercy Medical Center through automatic doors and wandering around the lobby, 20 blocks from home. It just so happened that Dale's wife, Nancy, was in the same building, recovering from surgery related to her battle with uterine cancer. "She was on a mission that night to see her mom, but she couldn't find the right elevator to take," Franck says. It isn't clear how Sissy reached her destination. "The only thing I could think of was that Sissy used to ride with me to pick up my wife from work next door to the hospital," he says. "But we've never walked that route before." Franck's daughter went to pick up the lost pup and surprised her mom with a visit before heading home. "My wife was like, 'How'd you get her in here? Did you sneak her under your coat?'" Franck says. Nancy tells KWWL that Sissy's visit was "a big boost—it helped a lot, just to see her and talk to her."
