3. Etymology: from 1646, formed in English (perhaps by influence of French veterinaire) from Latin veterinarius, "of or having to do with beasts of burden"; also, "cattle doctor", from veterinum, "beast of burden", maybe from vetus,"old"; possibly from the notion of being "experienced", or being "one year old"; hence, strong enough to pull burdens.

Another theory connects it to Latin, vehere "to draw, to pull", based on the notion of "used as a draft animal".
