Countryfile presenter Adam Henson has lent his support to the Guide Dogs charity, starring in a video in which he learns about the buddy dog service.

Henson met Evie, 16, and her buddy dog Uma, who 'helps her to overcome barriers around her vision impairment', and he commented 'When my late nephew Ben lost his sight at five years old, it brought home to me the challenges facing families with a visually-impaired child. Animals had a wonderfully calming and therapeutic influence on him, dogs in particular, so I fully understand the incredible impact that Uma has had on Evie... listening to her explain how Uma has given her back her confidence was inspiring'.
