One persistent pup showed just how strong the bond is with her owner. 

Nancy Franck has been at Mercy Medical Center in Cedar Rapids, Iowa for the last two weeks following cancer-related surgery. 

Her miniature schnauzer named Sissy missed her so much, that last Saturday she decided to go pay her a visit. 

Sissy is said to have walked at least 15 blocks on her own to the hospital to find the woman.  

The family is shocked that Sissy knew where to go, since they have never taken her to the hospital before.

KCRG reported:

“We looked up and there was this dog just that was just running across the lobby,” said Mercy Security Officer Samantha Conrad.

It’s a surprise visitor no one expected: a dog in a hospital. Security cameras caught it all. Just like anybody would, Sissy wandered through two automatic doors and strolls right into Mercy Medical Center.

“We started looking at the tags and it had the address and we saw how far away this dog had lived, as far as going at least fifteen blocks to get here. So it was quite an amazing journey that this dog made,” Conrad said.

The security guard used the dog’s tags to call one of the owners at home, Dale Franck.

“I thought she just wanted to go someplace, but I didn’t know where and she had never run away before,” Nancy’s Husband Dale Franck said.
