(a) Any person who intentionally cuts or alters the bone, tissues, muscles or tendons of the tail of any bovine or otherwise operates upon it in any manner for the purpose or with the effect of docking, setting, or otherwise altering the natural carriage of the tail, or who knowingly permits the same to be done upon the premises of which he or she is the owner, lessee, proprietor or user, or who assists in or is voluntarily present at such cutting or alteration, is guilty of a misdemeanor, punishable by imprisonment for not more than one year, or by a fine of not more than five hundred dollars ($500), or both. If any bovine is found with the bone, tissues, muscles or tendons of its tail cut or altered as aforesaid upon the premises or in the charge and custody of any person, and the wound resulting therefrom is unhealed, such fact may be evidence of a violation of this section by the owner or user of such premises, or the person having such charge or custody.

(b) The provisions of subsection (a) of this section shall not apply to tail docking performed by a veterinarian for veterinary purposes, provided that the procedure is performed under the following conditions:
