Adam Parascandola of the Humane Society of the United States says many dogs had scars and marks consistent with fighting.
Thirty-nine-year-old Brian E. Denny of French Lick was arrested on a preliminary charge of possession of animals for the purpose of animal fighting contests and an outstanding warrant for battery. He was released on bond.
A phone number listed as Denny's was disconnected and he could not immediately be reached for comment.
