Dog fighting is a felony in all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. While dog fighting statutes exist independently of general anti-cruelty statutes and carry stiffer penalties than general state anti-cruelty statutes, a person can be charged under both or can be charged under one, but not the other — depending on the evidence. In addition to felony charges for dog fighting, 48 states and the District of Columbia have provisions within their dog fighting statutes that explicitly prohibit attendance as a spectator at a dog fighting exhibition. Since Montana and Hawaii do not have such provisions, a person can pay an entrance fee to watch a dog fight in either state and not be convicted under these statutes. Additionally, 46 states and the District of Columbia make possessing, owning or keeping a fighting dog a felony.
