Mad Dog Connelly, known as the “King of the Dog Collar,” stands at 5'9" and 230 lbs, bringing raw aggression and psychological warfare to professional wrestling. Hailing from Springfield, Illinois, Mad Dog has made his name across the globe with over 20 dog collar matches under his belt. Wielding a heavy steel chain attached to twin collars, one for him and one for his next victim, he sets out to make each opponent "live their truth" through punishing battles. His relentless forward momentum creates a sense of chaos and excitement that grips fans across San Francisco and the wider Bay Area pro wrestling scene. Mad Dog isn’t just wrestling — he’s a full-force experience.
