The breed of dog that is often referred to as the "Firehouse Dog" is the Dalmatian.

Dalmatians have a long history of working with firefighters and have traditionally been the mascot of fire stations in many countries, including the United States. They are known for their energetic and friendly personality, as well as their distinctive black and white spotted coat. Dalmatians have a strong work ethic and are highly intelligent, which makes them well-suited for a variety of roles, including serving as firefighters' mascots. In this role, they are often responsible for providing companionship and morale-boosting support to firefighters, as well as serving as a symbol of the fire service.
