An official health certificate shall show proof of rabies vaccination within the previous 12 months.

In addition to the penalties set forth in this section, failure to provide such notice shall render a purchase agreement void. A violation of this subsection shall constitute an unfair or deceptive act or practice in the conduct of a trade or commerce under chapter 93A.

The appellant shall state the findings by the commissioner and the grounds of appeal therefrom. The court shall consider the proceedings de novo and the parties shall have right of exception and appeal.
