Pet dog walks two miles to find owner recovering from cancer

A 66-year-old woman receiving treatment for cancer in the US has received an unexpected visit in hospital - from her runaway dog.

Miniature Schnauzer Sissy walked two miles to reach the lobby of the Mercy Medical Center in Cedar Rapids, in Iowa. She was caught on surveillance cameras when she walked through the hospital entrance, and continued to sniff her way round the hospital looking for owner Nancy Franck.
