Video: Cancer patient thanks pet dog for sniffing our disease

A woman from Newark has described her pet dog as a guardian angel after it sniffed out a cancerous lump in her breast. Sharon Rawlinson's spaniel began pawing at her last November, so much that the 43 year old couldn't ignore it and went to her GP.

The doctor told her she had an aggressive tumour which would need chemotherapy and an operation. She's now waiting for the results of her first round of treatment.
