I think horses are beautiful creatures. But, I imagine they are hard to train and need a good horse trainer?
I agree, they're responsible for their physical needs in addition to teaching them behaviors and coaching them for events.
I think it would be fun to be able to train a horse, if you have the skills. I wonder, does a horse training have to go to school for that, or is it learned from years of interactions with horses?
I'm not really sure but I think it varies depending on what kind of training you'd be doing. Originally horses were trained for warfare and farmwork.
Yes, I would think having horses for farms years ago was a necessity, just as war. Now, they are mostly for recreation, in many cases.
They first started using horses for help with wars over 5,000 years ago. Could you imagine using a horse in a war today?
