Nope! And i would rather not have one. From what i know from a couple of my horse-savvy friends, they are a real hassle. I'm not very fond of horses either, although i have nothing against them. They're fun, but not my cup of tea.
Also, i could not imagine, unless the owner lived in the barn, how they could bring their horse inside for grooms and cuddles. Although i am sure that horses aren't kept for cuddles and super close company like many other smaller pet mammals/amphibians/snakes/aranchids/ etc.
