Horses are livestock. They are not pets. You don't bring them inthe house and “pet“ them. You keep them in open or enclosed outdoor areas just like you do cows, sheep, goats, pigs, etc. You don't own them as companions, household “pets“, you own them to ride or drive. If you choose to do nothing but pet them, they are still not pets. You CAN pet cows and goats, etc, but they are not meant to be, nor do they make very good pets. Never advocate for horses to be classified as pets; PETS and products meant for pets are TAXABLE. That's how the government makes more money, buy taxing pet supplies. You own a horse, you own livestock. Period.
