Dorado Alerts
Smoke begins to rise from the house. Dorado barks to alert the family that there is trouble. When they hear the barking, Dorado's family knows that something is wrong. While Dorado's owner calls 911 for help, Dorado sniffs out the appropriate exit routes. He jumps up to test the door handle with its paw. The knob is warm but not hot. Dorado barks three times to alert his owner that it is the right door to use. The family makes a swift exit from the house and waits outside the yard for the fire trucks to arrive. Because Dorado is trained for rescue procedure, Dorado's owner and his family are able to safely escape the house.
