A horse named Arthur was bred and sold while his foal-mates stayed behind. After four years, Arthur's original owners repurchased him and Arthur and his friends were reunited. Did this loving, gentle creature remember his buddies?

From Sue Blagburn, Arthur's human, who posted the video on her YouTube channel:

"So do horses remember each other and have emotions?

"On the 14 December 2012, I repurchased Arthur, a horse that I bred but had to sell four-and-a-half years previously in 2008. During this period two of Arthur's playmates from 'foalhood,' William who had been with Arthur since they were foals and Harry who arrived as a foal a year later stayed with me during a transition from running the busy graphic design business to working in equine facilitated learning and therapy. We had a few moves, and Harry and William had shared their lives with many other horses and ponies since spring 2009. Mustons Field, near the village of Hazelbury Bryan the place in Dorset where I used to live and all my horses and ponies grew up in has long been sold, and this reunion happened far away in a village called Firle in East Sussex, in a field William and Harry had only lived in for two weeks, whilst I was studying in this area, so there was nothing familiar. Would Arthur now aged eight-and-a-half, a thoroughbred sports horse that has spent the last four and a half years in a high class private competition yard BE eventing have any memory at all of the two hairy New Forest pony playmates he once shared his youth with? And likewise would William and Harry recognize that little thoroughbred guy who was once their best mate?

"This five minute film is the editing down of almost an hour of extraordinary footage of amazing hugging and communicating, that even I didn't think would be quite so loving and extraordinary.

"It is now May 2015 and I thought I would give you an update. This magical horse reunion was the beginning of a new adventure for Arthur, William, Harry and myself... We now have a wonderful home in South Dartmoor where we run Adventures with Horses, Equine Facilitated Experiential Learning. Arthur, William and Harry have become incredible guides and coaches for us human beings, by just being horses! Please see more at https://www.adventureswithhorses.co.uk/
