As Javier's aunt later wrote online, the dog confronted the intruders — who responded by attacking him. The dog then retreated, though he wasn't out of fight.
"Rex stormed back to the upstairs floor all beat up and bloody from the beating to check on his master who was still hiding in the closet," Susy Cadena wrote. "Soon, the burglars proceeded to the upstairs floor and trashed all the bedrooms. As they entered the room where my nephew was hiding in the closet, Rex came out with the little strength he had left in him and threw himself at them as he knew my nephew was in danger."
The thieves then shot at Rex, striking him at least three times. They then fled the scene, leaving Javier unharmed.
Rex's new fight began.
