Today we pay homage to the firefighters that lost their lives and those that were injured in the Houston fire.
I found a great link that tells the story of how the Dalmatian became the symbol of the Firehouse.
Because of the dog/horse bond, the dalmatian easily adapted to the firehouse in the days of horse-drawn fire wagons. Since every firehouse had a set of fast horses to pull the pumper, it became common for each group of firefighters to keep a dalmatian in the firehouse to guard the firehouse and horses. When the alarm came in, the dalmatian led the way for the horse-drawn pumper. In this way, the dalmatian became the firefighters’ companion and a symbol of the fire service. Today, dalmatians are still found in many firehouses in England, Canada, and the United States.
