When Monty Don's golden retriever Nigel became the surprise star of BBC GARDENERS' WORLD, padding along quietly behind his owner and yet stealing every scene - inspiring fan mail, birthday cards and his own social media sites - Monty wanted to explore what makes us connect with animals quite so deeply. In many respects, Nigel is a very ordinary dog: charming, handsome and obedient, as so many are. He is also a much-loved family pet. By telling Nigel's story, and those of all the other dogs in his life, Monty explores the special place our furry friends occupy in our lives, and celebrates the deep love we have for them.
