Carson City Fire units were dispatched to a structure fire at 310 S. Carson Street, the St. Charles Residential Hotel. The first arriving firefighters observed smoke from the second floor of the hotel. Crews quickly made entry into the smoke filled apartment and located an unconscious small dog. Firefighters also confirmed the fire had been extinguished by a working fire sprinkler. Had the building not had fire sprinklers the fire would have been much more serious. The dog was resuscitated and taken to a local veterinary hospital by firefighters. The damage to the hotel is estimated to be $10,000. The cause of the fire is currently under investigation. A total of 17 firefighters responded to the incident.
