TV presenter Kate Humble has been announced as ambassador for Medical Detection Dogs charity, which uses the olfactory power of dogs to detect diseases in humans, such as cancer in urine samples.

The charity also trains dogs to assist individuals with long-term life threatening diseases such as brittle type one diabetes. Humble, who first visited the Medical Detection Dogs centre in May, commented 'I was utterly blown away by my day at Medical Detection Dogs. The work they are doing is extraordinary and, although of course it sounds cliché, truly life-changing. I was delighted to be asked to be an ambassador for Medical Detection Dogs and had no hesitation in agreeing'.
