Monster, a 6-year-old male black Doberman alerted his family to a house fire.
Evelyn Aguilar and her many children were sleeping in the Beltsville, Maryland home when fire broke out.
The Doberman was outside the home at the time and he barked and jumped repeatedly on a sliding glass door to get someone's attention.
Everyone got out of the burning house safely. One firefighter sustained burn injuries. He was treated and released at a local hospital.
The family was just prior to the fire contemplating giving Monster away because money is so tight these days, but after this event, they have decided to keep him.
This is not Monster's first heroic effort. This awesome Doberman scared away an armed burglar a couple of years ago.
