Dog fighting is a felony in all 50 US states but persists as an underground activity, causing severe suffering for thousands of dogs.
Dog fighting causes acute and prolonged suffering: fighting injuries, chronic pain, infection from untreated wounds, and psychological harm from isolation and repeated traumatic experiences. Dogs who lose are often killed by handlers. The isolation and chain confinement outside fights represents daily welfare harm beyond the fight itself. Dogs bred for fighting are often capable of rehabilitation and adoption despite their backgrounds.
