Do you want to have to license your horse, pay a fee, and have it wear a license tag?
Do you really
want your vet to notify the county in which you live that you didn't vaccinate your horses on their set time schedule?
Do you want to have AC visit because you didn't vaccinate your licensed, tagged horse when the vets said it was due?
Do you want AC to have the ability to take your horse if it isn't licensed, tagged, and vaccinated per their statutes?
Horses should never
lose their livestock status and be legally considered pets, and won't be if I have anything to say about it.
