There is no specific horse you have to use for horseback riding, as long as the horse is trained.
think about if your riding a bike, or a car, or a motorcycle. you want to be as much long as a distance away as the object that your on. so, you should be about one horse apart from each other.
The horse has been domesticated for thousands of years. That's about how long Moroccians have been riding horses.
As long as it takes for you to master the art of riding a horse.
A long time.
There is a horse called Hugo because at my old horse riding school there was a horse called Hugo. Unfortunatley i have forgotten the name of my old riding school because it has been such a long time.
They are long pants normally used for horse riding ;)
as long as they are strong boots
Long distance
Spelling a horse means to take it out of work for a while,to have a brake of riding and stuff.Kinda like a long holiday for a horse
not unless you are riding the horse, but i would suggest not to over work the horse, and to clean the horse once you have finished riding and taking off all tack, and to let it have a break.
It's different for everyone, you should consult your riding instructor to see if they think you are ready. I took lessons for 5 years before I got my own horses.
