A heart-warming new advert released by Guide Dogs shows the drastic changes faced by two brothers when one starts to lose his sight.
From sibling rivalry to the challenges of learning important life skills as his sight deteriorates, the advert revolves around the relationship of two brothers over three generations.
It shows how sight loss impacts both their lives in different ways, and how Guide Dogs - which is the UK's leading charity for helping people with sight loss - is there to support at every step, not just with their famous dogs.
