Rex is on the mend and lucky to be alive. The 2-year-old German Shepherd was shot several times protecting his owner. Rex and 16-year-old Javier were home alone when someone allegedly broke in. Javier told local news stations that he heard someone bang on the glass door of the house and then heard it shatter. While he hid in a closet and called 911, he says Rex ran to confront the intruders. InsideEdition.com's Mara Montalbano (https://twitter.com/MaraMontalbano) has more.
