Since 1931, the animals have helped thousands of blind and partially sighted people with everyday tasks like crossing the road and avoiding obstacles when walking.
By doing so, the dogs support the visually impaired to get out and about, improving accessibility, confidence and independence.
In the US, miniature horses also take on that role – and the idea has now spread across the Atlantic where the pioneering Digby is being trained here in Yorkshire as the country’s first guide horse.
As the Royal National Institute of the Blind rightly points out, individuals have different preferences – and guide horses would give people more choice and a much-needed alternative for those who suffer from dog allergies or phobias.
Let’s hope more follow in Digby’s footsteps, or rather, his hoof prints.
