Hello, I just wanted you to know I own a horse. I just changed her name to beauty
What great creatures. They have evolved from multi-toed creatures to a single hooves one. 
If you only knew. Mine has a horn between it's head and can fly. She is truly my best friend.
I'm not sure that is a horse, of all the specialized vocabulary used to describe the size, color or marking, there is not horned breed.
