So what's on the list of 'Desert Island' Books? I like books that make sense to me.
The latest addition would be "The Essence of Good Horsemanship" by Ross Jacobs - a straightforward book with a pragmatic and practical approach to horses. I particularly like his emphasis on the horse's Primary Thought and how everything stems from the need to have an influence on that.
Kelly's books are always a refreshing read, with loads of good exercises you can do with your horse.
and if I was allowed a 'Complete Works of..." it would be Mark Rashid because his books are so readable even if you don't have a horse to work with.
Riding-wise I'd choose Heather Moffett and Perry Wood
For clicker training I always recommend Ben Hart's book "Clicker Training for Horses" which could do with some colourful pictures but makes total sense.
and I also love Tom Widdicombe's book Be With your Horse for it's unemotional approach.
If I was only allowed one book then I guess I'd grab my own, not just because it's my only contribution to the world, but also because there might be semi-feral ponies on my Island.
