I've never seen a guard horse in Japan. I don't think we have any....
I visited Horse Guard Parade because I was interested in how they are trained and if they behave different from other horses.
Actually, most of horses in our world are domestic and termed. I've seen some wild horses in United States originally came from Spain about 300 years ago. They were as if be born to cultivate soil for farming. They didn't look like thoroughbreds at all. They had strong legs. Therefore, before I visit Horse Guard Parade, I imagined horses something in between thoroughbred and wild horse. I also imagined the animal lacking emotion simply because they are trained for war. The life with an apparent absence of emotion makes me think always.
Oh, the horse is so gentle...
It seems he prefers girls rather than males...
This horse know how to make audiences happy...(!!)
I found Horse Guard Parade looks beautiful because of the rider, and found horses are enjoying their life --which is very good! A plan a guard horse as my motive was cancelled.
