Mass. Gen. Laws ch. 272 § 92
An owner or claimant aggrieved by such judgment may, within twenty-four hours after the entry thereof and before its execution, appeal therefrom to the superior court; and all proceedings upon and after such appeal, including the right of exception, shall conform, so far as may be, to those in criminal cases, except that before such appeal is allowed the appellant shall recognize to the commonwealth in the sum of two hundred dollars, with sufficient sureties, to prosecute his appeal and to pay such expenses of the prosecution as the court may order and such expenses as may be thereafter incurred in the care and keeping of the birds, dogs or other animals claimed by such appellant if final judgment is rendered against them, and to abide the judgment of the court thereon. Upon the final judgment, the birds, dogs or other animals held in custody to abide such judgment shall be disposed of, under the direction of the superior court, in like manner as the court or justice might have disposed of them if no appeal had been taken. During the pendency of the appeal, all birds, dogs or other animals adjudged forfeited shall be kept in custody in a place other than that from which they were taken.
